There’s something about mountain lakes in Switzerland that gets under your skin — in the best possible way. Maybe it’s the way turquoise water mirrors towering peaks, or how the silence feels deeper at altitude. Maybe it’s the hike that makes the first glimpse of a lake feel earned, or the shock of icy water on a hot summer day. Whatever it is, Swiss alpine lakes have a quiet, lasting kind of magic.
Over the years, I’ve explored Switzerland in search of these places — glacier-fed lakes glowing milky blue beneath dramatic peaks, hidden turquoise pools tucked into high valleys, and peaceful alpine ponds where time seems to slow down. Some are world-famous, others feel like well-kept secrets, but all of them left a lasting impression.
This article is a personal collection of my favorite mountain lakes in Switzerland, written for nature lovers who want to explore and experience them for themselves. Spread across different regions of the country, these lakes vary widely: some are easy to reach by public transport, while others require a rewarding hike. Some are perfect for a cold swim on a summer day, others invite you to sit, breathe, and simply take it all in. If you’re looking for the most beautiful alpine lakes in Switzerland — whether to visit, hike to, or dream about — you’re in the right place.
1. Oeschinensee
Oeschinensee doesn’t just impress — it stuns. The first glimpse of that unreal turquoise water, framed by towering rock walls, honestly feels like stepping into a fantasy novel. Located high above Kandersteg in the Bernese Oberland, this lake is pure alpine drama in the best possible way.
And the best part? It’s surprisingly easy to reach. Take the cable car from Kandersteg, then follow a gentle 25-minute walk through alpine meadows until the lake suddenly reveals itself. From there, the day is yours: rent a rowing boat, grill your lunch by the shore, wander the trails for panoramic views, or simply sit still and stare (highly recommended).
Family-friendly, wildly photogenic, and endlessly awe-inspiring — Oeschinensee easily earns its place among Switzerland’s most breathtaking lakes.
2. Stellisee
If capturing the perfect Matterhorn reflection is on your bucket list, Stellisee is where the magic happens. Perched at 2,537 meters above Zermatt, this quiet mountain lake offers one of the most iconic views in Switzerland — with fewer crowds and a wonderfully peaceful atmosphere.
The secret? Go early. Really early. Take the gondola from Zermatt up to Blauherd, then hike for about 20–30 minutes to reach the lake just as the first light touches the peaks. When the Matterhorn appears perfectly mirrored in the still water, time seems to pause for a moment.
Up here, in the crisp morning air, with nothing but mountains and silence around you, the Matterhorn almost feels unreal — like a painting that somehow escaped its frame.
3. Klöntalersee
Welcome to Klöntalersee — often lovingly called the fjord of the Glarus Alps. This glassy lake, cradled by towering rock walls and dramatic peaks, is one of those places where everything feels calm, balanced, and beautifully still.
The trail looping around the lake is a favorite for good reason. With gentle inclines and only about 145 meters of elevation gain, the 12.65 km route is manageable, relaxed, and perfect for all nature lovers and adventurers. Plan around 3.5 hours and plenty of photo stops along the way.
Dreamy viewpoints of the lake and the Glärnisch mountains appear again and again, and there are cozy places to stop for food or a drink along the route. And if the weather cooperates? A refreshing swim in the crystal-clear water is the perfect grand finale. Klöntalersee is best reached by PostBus from Glarus (mid-May to mid-October). Pure alpine serenity.

4. Seealpsee
Seealpsee is one of those places where you don’t need many words — the scenery does all the talking. Tucked into the Alpstein region of Switzerland, this small mountain lake sits in a spectacular natural bowl, surrounded by lush alpine meadows that gently cling to the slopes of the surrounding mountains. Just for its setting alone, a visit here is more than worth it.
On calm days, the peaks of the Alpstein — including the Säntis and its rugged neighbors — reflect softly on the lake’s surface, blurring the line between sky, mountain, and water. The lake itself is crystal-clear and wonderfully clean, shifting between shades of deep blue and vibrant green depending on the light.
From Wasserauen, it’s about a 45-minute uphill hike to reach Seealpsee. Yes, your legs might protest a little — but your eyes will thank you endlessly. Once you arrive, there’s no rush. Rent a rowing boat and glide across the water, enjoy a hearty meal at the mountain inn, pick up fresh cheese straight from the alpine dairy, or stretch out in the grass and let the mountains hold your gaze.

5. Trübsee
Trübsee proves that “easy to reach” doesn’t have to mean “boring.” Perched halfway up Mount Titlis near Engelberg, this lake is ridiculously accessible — just hop on the cable car and walk a few minutes down to the shore. No sweaty hike required (unless you want one).
The lake shimmers in a dreamy blue-grey color — true to its name, Trüb, which means cloudy, but in a beautifully mysterious way. You can rent a rowing boat, stroll the circular trail, or simply sit back and watch paragliders glide silently overhead.
It’s incredibly family-friendly and works in every season, whether you’re hiking in summer or wandering through snowy landscapes in winter. Trübsee is also a perfect stop on the way up to the Titlis Glacier.
6. Caumasee
If Switzerland ever decided to go tropical, Caumasee would be the result. Located in the Flims region of Graubünden, this lake is often called the “Lagoon of the Alps” — and once you see that unreal turquoise water, you’ll know exactly why.
Surrounded by forest, Caumasee has a laid-back, beachy vibe that feels wildly unexpected in the mountains. Getting there is easy: a short walk from Flims Waldhaus or a charming little funicular ride that already feels like part of the experience.
In summer, this is the place to swim, paddleboard, or lie in the sun pretending you’re somewhere far more exotic. There’s even a small island in the middle of the lake — and yes, you can swim out to it. Alpine Caribbean dreams? Fully approved.
7. Crestasee
Just a stone’s throw from the famous Caumasee lies a much quieter sibling: Crestasee. Crystal-clear water, deep green forest, and an atmosphere so calm it almost feels secret — like nature gently whispering, this one’s just for you.
At 375 meters long and 180 meters wide, Crestasee may be small, but its charm is huge. It’s officially protected as a natural monument of regional importance in Graubünden, and it’s known for its excellent water quality — perfect for a refreshing dip after a hike.
There’s a catch (and it’s part of the magic): you can only reach Crestasee on foot. Either take the scenic 2+ hour walk from Flims via Caumasee and the Il Spir viewing platform, or choose the shorter 20-minute stroll from the “Trin, Felsbach-Crestasee” bus stop. Once there, you’ll find a cozy kiosk, a public grill area, and a restaurant just uphill. Tranquil, tucked away, and absolutely worth the walk.
8. Mettmensee
Mettmensee — also known as the Garichti reservoir — is one of those places that feels beautifully untouched. Sitting at 1,622 meters in the Freiberg Kärpf in the Glarus Alps, it lies within Switzerland’s oldest wildlife reserve, surrounded by silence and open space.
The 500-meter-long lake is lined with fire pits and easy paths, perfect for lingering, fishing, or a relaxed stroll around the water. The full loop takes about 30 minutes — or much longer if you keep stopping to admire the views.
Mettmensee is also the heart of the Mettmen Alp and a fantastic starting point for hikes, whether it’s 2½ hours up to the Leglerhütte or a longer crossing over the Wildmadfurggeli to Elm.
One important detail: the cable car from Kies to Mettmen can only be reached by bus — arriving by private car is no longer possible. But honestly? That little extra effort makes the experience even more special, then the bus ride up to Kies is an adventure in itself!
I’ve shared all the details in my full article about visiting Mettmensee — a true hidden gem.
9. Arnisee
Arnisee is one of those lakes that makes you wonder why it isn’t world-famous — and then you realize it’s probably better that way. Hidden above the Reuss Valley in the canton of Uri, this peaceful alpine lake sits at around 1,360 meters and feels like a gentle pause button on life.
A small cable car from Amsteg or Intschi carries you up the mountainside, often alongside locals heading up for the day. Within minutes, the world below fades away, replaced by forests, meadows, and wide open views.
Arnisee is perfect for picnics, lazy loop walks, or longer hikes that reward you with sweeping panoramas. Calm, grounding, and quietly beautiful — it’s the kind of place that invites you to stay a little longer than planned.
10. Talalpsee
Talalpsee is, for me, one of those places of power. The kind where you arrive, sit down, and immediately feel your shoulders drop. Where words get quieter and your thoughts slow down on their own. No effort required.
Perched above the village of Filzbach in eastern Switzerland, this small mountain lake is wrapped in emerald-green meadows, curious cows, and rugged peaks that feel both protective and wild. It’s scenic without trying too hard — and that’s exactly what makes it so special.
Getting there is refreshingly simple: take the cable car from Filzbach up to Habergschwänd, then stroll along an easy, beautiful 30-minute hike to the lake. No stress, no drama. Just fresh air and anticipation.
Once you arrive, time seems to stretch. Pack a picnic, dip your feet into the cold, clear water, and let the mountain silence work its quiet magic. And if you’re feeling a little playful (or just don’t feel like walking back), you can hop on a scooter for the ride down — because alpine adventures can absolutely be fun and peaceful.
11. Schwarzsee
Schwarzsee — the “Black Lake” — carries an air of mystery that you feel the moment you arrive. Especially early in the morning, when soft fog drifts across the water and the surrounding peaks seem to whisper old alpine stories. It’s moody in the best possible way.
Even though Schwarzsee is popular, it never feels overwhelming. A gentle 4 km walking path loops around the lake, perfect for an easy, unhurried stroll. You can rent pedal boats, linger by the shore, or settle into one of the lakeside restaurants for fondue with a view — because really, this is Switzerland.
Easily reached by car or public transport from Fribourg, Schwarzsee makes a wonderfully uncomplicated day trip. And yes — depending on the light, the water truly does turn deep, inky dark, fully living up to its dramatic name.
If you’re curious about the lakeside hike known as the “Witches’ Path” and the little surprises hidden along the way, I’ve shared everything in my Schwarzsee blog post.
12. Bannalpsee
Ah, Bannalpsee. A true insider tip — and one of those places you almost want to keep to yourself. Tucked high above Engelberg in Nidwalden, this peaceful mountain lake feels beautifully removed from the noise of the world.
A tiny, charming cable car takes you from Oberrickenbach up to Bannalp. It’s delightfully old-school and sets the tone perfectly. From there, a short walk leads you to the lake, where rugged cliffs rise dramatically and reflections ripple so perfectly they look painted.
There’s even a cozy mountain restaurant right by the water, serving simple, hearty local dishes — exactly what you want after breathing in fresh alpine air all day. Bannalpsee isn’t flashy. It doesn’t try to impress. It just is. Calm, honest, deeply soothing. Absolute heaven.
For the full hike and all practical details, you’ll find everything in my Bannalpsee article.
13. Golzernsee
Golzernsee is one of those places that gently forces you to slow down — even if you arrived with a full to-do list in your head. From Bristen in the Maderanertal (Canton Uri), a small cable car quietly lifts you up to Golzern at 1,400 meters. And just like that, everyday life feels wonderfully far away.
From the mountain station, it’s an easy 20-minute walk along a natural road, past blooming alpine meadows and postcard-perfect farmhouses. Then, almost shyly, Golzernsee appears.
In summer, the water warms up to around 20°C — yes, warm enough to swim without screaming. Add fire pits scattered around the lake, and you’ve got the perfect spot for a relaxed swim-and-grill day with mountain views. Golzernsee is uncomplicated, friendly, and incredibly grounding.
If you want more details (or feel like diving a little deeper), I’ve shared everything in my Golzernsee experience article.
14. Gletscherseeli
Wild, raw, and slightly otherworldly — Gletscherseeli isn’t a lake you simply visit. It’s a lake you experience. Sitting high above the Klausen Pass at 2,098 meters, right at the foot of the mighty Clariden massif, it feels like a glimpse into another time.
Its milky-grey color instantly reveals its origin: glacier meltwater filled with fine rock particles. The result is a constantly shifting, surreal shade that looks almost lunar under changing light. Scree, ice, and rugged alpine terrain surround the lake, creating a landscape that feels powerful and untamed.
The water continues its long alpine journey via the Fätschbach towards the Urnerboden and into Glarus — a quiet reminder of how everything in the mountains is connected. From the Klausen Pass, the lake is reached in about an hour on a marked hiking trail.
If this kind of wild beauty speaks to you, you’ll find more details in my Klausen Pass & Gletscherseeli blog post.
15. Glattalpsee
Glattalpsee feels like stepping into a high-alpine dream — vast, quiet, and incredibly pure. Located at around 1,900 meters in the Muotathal (Canton Schwyz), the lake lies within a dramatic karst landscape and is famous for its extremes. In winter, this area regularly records some of the coldest temperatures in Switzerland.
In summer, though, Glattalp transforms into a peaceful hiking paradise. You can reach it by cable car from Sahli to Glattalp, or on foot if you’re craving something more challenging. Once there, gentle circular paths invite you to wander slowly, while the surrounding peaks stand watch in silence.
With mountain inns and a SAC hut nearby, Glattalpsee is perfect for longer stays — whether you’re traveling with family or venturing out as a seasoned mountaineer. I’ve shared my full hiking experience in my Glattalpsee blog post.
16. Oberblegisee
Deep blue, mysterious, and almost unreal — Oberblegisee is one of those lakes that makes you believe in alpine magic all over again. Often counted among the most beautiful mountain lakes in Switzerland, it also carries an air of mystery thanks to its unexplored underground outflow.
Wild streams, rich alpine flora, and steep mountain walls frame the lake like a natural amphitheater. There’s no shortcut here — Oberblegisee has to be earned on foot. From Braunwald, take the gondola to Grotzenbühl and follow a gently descending trail with breathtaking panoramic views. The path winds through meadows and light forests before reaching the Bösbächi valley.
A stop at the cozy Bächibeizli is almost mandatory — food just tastes better after a hike. From there, a beautiful mountain trail leads you up to the lake itself.
I’ve shared the entire hike and all details in my Oberblegisee article — definitely worth a read if this lake has sparked your curiosity.
17. Voralpsee
Voralpsee is easy-going, friendly, and endlessly lovable. Nestled at 1,123 meters above sea level in Grabs (Canton St. Gallen), it lies in a gentle hollow on the Grabserberg, surrounded by alpine pastures and forests between the Alvier range and the Churfirsten.
The lake stretches long rather than round — about 550 meters in length — and a beautiful walking path loops all the way around it. Perfect for a relaxed stroll with big views and zero pressure.
Thanks to its easy access by bus and a short walk, Voralpsee attracts a wonderfully mixed crowd: hikers, families with picnic grills, bikers, and brave mountain-lake swimmers. In summer, it’s all about refreshing dips and long, lazy days by the water. Still mostly a local favorite — and that’s part of its charm.
If you’d like to know more, I’ve shared everything in my Voralpsee blog post.
18. Blausee
Blausee almost feels too beautiful to be real. Hidden in the Kandertal in the Bernese Oberland, this small lake is famous for its crystal-clear, deep blue water and the peaceful nature park surrounding it. It’s one of Switzerland’s most iconic lakes — and yes, it truly lives up to the hype. (Just don’t expect to swim here.)
I hiked down to Blausee from Kandersteg, and the walk was the perfect transition into the stillness waiting below. Once you arrive, the colors, reflections, and quiet atmosphere feel almost meditative. If hiking isn’t your thing, the lake is also easily reached by bus.
For my full experience and hiking details, head over to my Blausee blog post.
19. Hinterstockensee
Hinterstockensee is small, quiet, and beautifully placed. Located in the Simmental (Canton Bern) at 1,595 meters above sea level, it’s just a five-minute walk from the Chrindi mid-station of the Stockhorn cable car.
Despite its easy access, the lake feels peaceful and surprisingly untouched. It pairs perfectly with a visit to the Stockhorn and a light, scenic hike. This is the kind of place where you pause without checking the time — just breathe, look around, and enjoy.
I’ve shared more ideas on how to combine Hinterstockensee with a Stockhorn visit in my Stockhorn blog — a gentle adventure with big views and calm moments.
20. Bachalpsee
Bachalpsee is alpine poetry in lake form. Sitting high above Grindelwald, this iconic mountain lake reflects the snow-covered peaks of the Bernese Alps like a perfectly polished mirror.
To get there, take the cable car from Grindelwald up to First, then follow an easy and scenic 50-minute hike through flower-filled meadows where marmots often make surprise appearances. Honestly, the walk itself is half the joy.
Once you reach the lake, everything slows down. Sit on a rock, breathe in the crisp mountain air, and let the panorama do its thing. Bachalpsee isn’t just a view — it’s high-altitude therapy for the soul.
21. Riffelsee
Not far from Stellisee lies another Matterhorn masterpiece: Riffelsee. Small in size but monumental in atmosphere, this lake sits at 2,757 meters above Zermatt and delivers one of the most dramatic mountain reflections you’ll ever see.
At sunrise, the Matterhorn glows in shades of pink and gold, reflected perfectly in the calm water. Getting there is part of the adventure: hop on the Gornergrat Bahn — Switzerland’s highest open-air cogwheel railway — and ride up to Rotenboden station. From there, it’s a scenic 10-minute walk to the lake.
Riffelsee may be tiny, but the feeling it leaves behind? Absolutely colossal.
22. Silsersee
Silsersee, nestled in the Upper Engadin near St. Moritz, is a lake that effortlessly wears two faces. In summer, the calm, turquoise waters mirror the surrounding peaks and grassy meadows, inviting swimmers, sailors, and kayakers to linger. Gentle trails along the shoreline offer panoramic views of the mountains, while quaint villages dotting the lake add just enough charm without ever feeling crowded. A picnic on the lakeside, with the sun warming your back and the mountains reflected like glass, feels almost like stepping into a painting.
Come winter, Silsersee transforms into a serene frozen wonderland. Cross-country skiers glide over its icy surface, snow-dusted peaks shimmer in soft morning light, and the quiet is absolute — broken only by the occasional crunch of skis on snow. The lake’s magic lies in its duality: equally enchanting whether you seek summer adventure or winter stillness. Accessible from Sils-Maria by a gentle walk or cycle in summer, and by groomed trails in winter, Silsersee makes every season feel like a celebration of the Alps themselves.
Final Thoughts: Let the Mountains Lead the Way
Switzerland’s mountain lakes have a quiet way of staying with you. Long after the hike is over and the boots are back in the closet, it’s the stillness, the colors, the reflections, and those small, unplanned moments that linger. Each lake in this list offers something different — a sense of wonder, a deep breath, a feeling of coming home to nature.
And yet, these are only a few of Switzerland’s countless mountain lakes. There are so many more tucked away behind ridges, hidden above valleys, or waiting at the end of a trail — some I haven’t even discovered myself yet. That’s part of the magic: no matter how long you wander these mountains, there’s always another lake, another view, another quiet moment waiting.
You don’t need to see them all at once. In fact, they’re best discovered slowly. One hike, one picnic, one spontaneous detour at a time. Let curiosity guide you, trust your feet, and allow space for those pauses where nothing needs to happen.
