Hit the hiking trails
The easiest, cheapest and arguably most rewarding of things to do in Interlaken is heading out on one of the many hiking trails. Interlaken is surrounded by some of the highest mountains in the Alps, including the Eiger, Mönch, and Jungfrau, and a plethora of paths allow hikers to choose trails based on length of time and fitness level required. Options range from spots such as Panoramaweg, an easy two-hour circuit, to Pizol’s Five Lake four- to five-hour circuit, which is purportedly one of the best in the region. You can take a moonlit hike or use the help of a cogwheel train such as the one from Wilderswil to get to the kind of altitude where the views will give you the boost you need to keep walking. You can also trek between stations – why not take a downhill hike from Lauterbrunnen station to Stechelberg.
