So, you’re heading to Interlaken this summer? Fantastic choice! Nestled dramatically between the jaw-droppingly beautiful Lake Thun and Lake Brienz, with the snow-capped Alps playing peek-a-boo in the background, Interlaken isn’t just near water – it is water. When the Swiss sun starts shining, there’s only one place you’ll want to be: in, on, or floating blissfully across those shimmering turquoise surfaces. Forget about just dipping your toes; Interlaken invites you to dive headfirst into a world of aquatic alpine fun. Ready to make some waves? Let’s explore the best ways to get wet and wild (or wonderfully relaxed) this summer while Lake-ing it in Interlaken: the best water & lake activities in Summer
Interlaken the best water & lake activities in Summer
So without further ado lets jump into those streams, waterfalls, rivers and lakes and reveal to you Interlaken’s best water & lake activities and aquatic things to do in Summer.
The Aare River Float: Go with the Flow! (the classic)
This isn’t just an activity; it’s practically a Swiss and Interlaken summer ritual known among the Swiss as Aarebööttle !! Imagine this: grabbing an inflatable dinghy, a dry bag for your essentials, and launching yourself into the refreshing, crystal-clear Aare River. You’ll gently float downstream, passing charming villages, lush green banks, and soaking in those incredible mountain views. Start near Thun and drift towards Bern for the classic long haul, or enjoy shorter sections closer to Interlaken with a float from lake of Brienz towards the Unterseen old town. It’s pure, unadulterated relaxation mixed with stunning scenery. Just remember safety first – check conditions, know your exit points, and maybe pack a waterproof speaker for some chill tunes!
Kayak or SUP Paddle (the enjoyable)
Want to explore the nooks and crannies of Lake Thun or Lake Brienz at your own pace? Grab a kayak or a Stand-Up Paddleboard (SUP)!
- Lake Brienz: Famous for its intense turquoise colour and dramatic cliffs plunging into the water. Paddling here feels almost mystical. Explore hidden coves and enjoy the tranquility.
- Lake Thun: Larger and dotted with fairytale castles (like Spiez or Oberhofen), this lake offers wider vistas and charming lakeside towns to paddle towards.
Whether you’re gliding silently across glassy morning water or enjoying a midday paddle, it’s a fantastic workout with an unbeatable view. Rentals are readily available around both lakes.
Ultimate Alpine Glow: Sunset SUP & Sip ✨ (the Most Unique)
Okay, now listen up, because this is where Interlaken truly elevates the water experience. While paddling during the day is amazing, imagine gliding across the calm evening waters of Lake Thun as the sun begins its spectacular descent behind the Alps. This isn’t just Stand-Up Paddling; this is the Sunset SUP & Sip Adventure, and honestly, it’s pure magic.
What makes it so unique? It’s the combination: the gentle workout of paddling, the breathtaking beauty of an alpine sunset painting the sky and reflecting on the water, the peace of the lake as daytime boat traffic subsides, and capping it off with a well-deserved local drink (think Swiss wine or craft beer) right there on the water or shoreside as the last colours fade. Companies like Hightide offer guided tours ensuring you’re in the best spot at the right time, often including the board, guide, and that crucial celebratory sip. Compared to other water activities, this blend of active serenity, natural spectacle, and relaxed indulgence against the iconic Eiger, Mönch, and Jungfrau backdrop is an experience you simply won’t find anywhere else. It’s romance, relaxation, and soft adventure rolled into one unforgettable evening. This is how you truly ‘Lake it’ in Interlaken.
Jet Boating on Lake Brienz (the thrill)
Ready to swap serenity for speed? A jet boat ride on Lake Brienz is pure adrenaline! These powerful boats zip across the water, performing thrilling 360-degree spins, sharp turns, and sudden stops that send spray flying. It’s a high-speed sightseeing tour combined with a serious dose of excitement, all set against the backdrop of the Giessbach Falls and the surrounding mountains. Expect to laugh, scream, and get refreshingly soaked!
Canyoning in Nature’s Waterpark (the adventurous)
Okay, technically next to the lakes, but an absolute Interlaken must-do for thrill-seekers! Canyoning involves navigating mountain gorges by rappelling down waterfalls, sliding down naturally carved rock chutes, jumping into crystal-clear pools, and swimming through narrow passages. Local operators offer tours for various levels, from beginner-friendly descents in places like Saxeten to more challenging adventures in Grimsel or Chli Schliere. It’s an incredible way to experience the raw power and beauty of the alpine environment.
Lake Cruising: Scenery Served Daily (the relaxer)
Sometimes, you just want to sit back, relax, and let the scenery come to you. The scheduled boat services on both Lake Thun and Lake Brienz are perfect for this. Hop aboard a modern cruiser or even one of the beautifully restored historic paddle steamers! Enjoy a drink on deck, feel the breeze, and marvel at the castles, villages, and mountains gliding by. It’s a fantastic way to get between towns like Spiez, Thun, Brienz, and Iseltwald while enjoying the journey itself from a lake cruise with stunning scenery served on a golden platter.
Take a Dip & Embrace the Crystal Clear Alpine Waters (the refresher)
Don’t underestimate the simple, soul-refreshing pleasure of a swim in truly pristine alpine water! Interlaken and its surroundings offer incredible spots for a dip.
- Lakeside ‘Badis’: Interlaken boasts several fantastic lakeside swimming areas (‘Badis’). Popular choices like the Neuhaus lido on Lake Thun or the Bönigen lido on Lake Brienz offer easy access, pontoons, grassy areas, and that invigorating plunge into the turquoise depths.
- Mountain Lake Magic: For the more adventurous (and those willing to hike!), picture yourself cooling off in a high-alpine lake like the stunning Bachalpsee (near Grindelwald First). The water will be very brisk, but the surrounding panorama is unbeatable. Remember to check accessibility and conditions before heading up.
The clarity and colour of the water here are exceptional. On a hot summer day, immersing yourself in these lakes, whether easily accessible or earned via a trail, is pure bliss.
Stroll along an Alpine Shoreline (the meanderer)
The walk from Neuhaus to the St. Beatus Caves is a truly scenic and enjoyable experience, tracing the northern shoreline of Lake Thun before climbing above dramatic cliffs. The path initially hugs the lakeside, offering tranquil views of the shimmering blue water and the surrounding Bernese Alps. As you progress, the trail gradually ascends, leading you through lush woodlands and across charming bridges, with the sound of birdsong and the gentle lapping of waves as your backdrop. The route is well-marked and family-friendly, with benches and picnic spots along the way, making it accessible for walkers of varying abilities
Closer to the caves, the landscape becomes even more striking as the trail rises above sheer cliffs, providing breathtaking panoramic vistas over Lake Thun. The highlight of the walk is the approach to the St. Beatus Caves and their iconic waterfalls, which cascade dramatically from the cave entrance down the cliffside. The path here is partly carved into the rock, adding a sense of adventure as you traverse above the lake and marvel at the unique sight of water emerging from the mountain. The final ascent to the caves is a bit steep but manageable, and the reward is not only the natural wonder of the caves themselves but also postcard-perfect views of the lake and surrounding peaks, making the entire stroll a memorable and picturesque outing
