Unterseen
Unterseen is a small old town near the Interlaken West train station. It's not as crowded as Interlaken and has several shops and bakeries including a enormous Coop supermarket in which there is a large selection of groceries and chocolates. To get there, cross the bridge over the water near the train stop, walking in the direction facing away from Interlaken.
The Höheweg is Interlaken's main street which runs between Interlaken West and Interlaken Ost Railway Stations. On this street you will find many souvenir shops. Have a look at the "Japanese Garden", the 150-year old Victoria Jungfrau Grand Hotel, and don't miss the beautiful view of the famous snow-covered Jungfrau mountain from "Höhematte".
