4. Chill Local Spots (for low-budget adventures)
Burgseeli (Goldswil)
A warm, forest-lined mini-lake, perfect for swimming and relaxing, and mostly locals! Entry fee, but worth it.
🔹 Great for a calm afternoon away from the crowds.
Aare River Banks
Walk or cycle along the river — dip in, picnic, nap under the trees.
🔹 Favorite Balmers chill zone: Head to the area near Interlaken Ost, right by the bridge leading to the le Harder Kulm funiculaire. Vous trouverez des marches menant à l’eau et un espace gazonné pour vous détendre après votre baignade. Le courant devient plus fort vers le milieu, alors restez sur les bords pour une baignade plus sûre.
5. Gorges & Caves to Explore
If you’re looking for something wild and off the beaten path, Interlaken’s gorges and caves are pure natural drama.
Aare Gorge (Aareschlucht)
It is a narrow limestone canyon near Meiringen, where you can walk on suspended wooden platforms just meters above the rushing turquoise river — it’s an easy, family-friendly adventure with epic photo spots.

St. Beatus Caves
For something darker and deeper, on the shores of Lake Thun, the Saint Beatus caves let you explore underground waterfalls, stalactites, and echoing chambers in a mythical setting (legend says a dragon once lived there). Both sites are great for rainy days or when you want a cool break from the summer sun.
