Go canyoning with Alpin Raft. If you've come to Interlaken and are looking for adventure, this is the thing to do. Canyoning is one of the coolest and most unique adventure experiences I've ever had. They gave you all the gear you need, and you spend the day sliding down rocks, jumping off waterfalls, rappelling off cliffs, etc. I've never met anyone who didn't fully enjoy their experience, and it truly is a unique one. If you can afford it, and want to do something awesome, go for the longest canyon (Chli Schliere). The guides are helpful, funny, careful, and experienced. They tell you exactly what to do, step you through it, and ensure that you're safe. Read on tripadvisor for more reviews, but if this is all you see, just be confident knowing that you'll have a great time. read more
