If you wanna experience something totally different and you are in the Brienz/Interlaken area, this fun activity for up to 6 people might be for you. What to expect: In Brienz you head to the office of Pirate-Bay. There you jump on a floating tub, with around 38-40 degree celsius water temperatures. Amazing if you think that the lake of Brienz is sometimes below 15 degree. Pack some beers, music and have a good time. Price: It depends on how long you wanna experience, the day of the week and how many people you are. It ranges between 250chf and 430chf. Tip: Its booked out pretty quick, so book it way in advance.
