Day 1 — Interlaken: forest walk up to Harder Kulm
- 🥾 On the first day, it’s best to do an acclimatization walk right from Interlaken: an ascent on the well-known trail to Harder Kulm through the forested slope above town. This is a classic route in the style of forest + viewpoint mountain + observation platform. The active part of the day takes about 3.5–4.5 hours if you hike up and descend by funicular, or about 2–3 hours if you limit yourself to a short walk at the top after taking the funicular up. If you walk up from below, the elevation gain is about ≈750 m, difficulty moderate; if you go up by funicular and walk only at the top, the outing will be easy. The route suits an average tourist because it is marked, popular, has no technical sections, and requires nothing more than comfortable shoes and a supply of water. From the top, you get views of two lakes at once, the Aare valley, and the famous panorama of Eiger, Mönch, and Jungfrau. It’s best to set out in the morning or closer to evening, but keep in mind that the forest trail is less comfortable to descend at dusk. In spring and autumn after rain, the ground may be slippery, and in the shoulder season it’s worth checking the funicular operating hours in advance so you don’t get stuck without a ride down.
