Interlaken is a municipality in the Interlaken-Oberhasli administrative district in the Canton of Bern in Switzerland, a well-known tourist destination in the Bernese Oberland. Interlaken is located between Lake Brienz to the east and Lake Thun to the west in the area called Bödeli. The town takes its name from its geographical position between the lakes (in Latin inter lacus). The Aare River flows through the town connecting the lakes.
The town is a base from which to explore the surrounding areas by train or bus. One of the main attractions is the Jungfrau, (4,158 m (13,642 ft)) and the Jungfraujoch railway station (3,450 m (11,320 ft)). Many hotels are located along the Höheweg. Mystery Park, a paranormal-based theme park owned by Erich von Däniken, was closed in 2006 after three years because of financial difficulties but re-opened in 2009. Interlaken is a destination for backpackers throughout the year. Interlaken has numerous backpacker-friendly hostels and companies providing guided services in skydiving, canyoning, hang gliding, paragliding, and skiing.
