Interlaken is in an absolutely stunning area, and it's an outdoor lover's paradise. It's well connected via train, bus, and ferry boat, which makes it so easy to get around to anywhere in the country. Extremely clean. Almost everyone speaks English. Lots of young people in this area who visited once and then came back to live because they loved it so much. If you make it to Interlaken, make sure you go into Lauterbrunnen for the most stunning views and villages.
