From Interlaken-West station, the path traces the Aare to Unterseen before joining the varied lakeside path to Lake Thun. Glistening waters, lightly forested areas and avenues of venerable old trees catch the eye, as do the heritage-protected castle ruins of Weissenau and the Weissenau-Neuhaus nature reserve. Much of the lakeside path leads through this protected area, a park-like landscape of woodland, shrubbery and open reed beds. The shallow shore zone with its large reed belt is especially important to the waterfowl on a lake with few flat banks; more than 200 bird species have been identified.
From Interlaken-West station (elevation of 563 metres), follow the Aare towards Unterseen (567 metres), then continue along the Aare to the point just before it flows into Lake Thun following signs to the Weissenau ruins (559 metres). Now follow the path through the Weissenau nature reserve to Neuhaus (560 metres).
Easy walk on signposted paths. Follow the yellow signs; additional signposts have a green square and route number 449 for «Unterseen lakeside path» (barrier-free). Difficulty: T1.
