Day 1 — Zermatt: the 5-Seenweg five lakes route
- 🥾 The main start of the trip is the classic 5 Lakes Walk in the Sunnegga–Blauherd area. This is a high-altitude but well-known and safe scenic walk through alpine lakes, meadows, and gentle mountain slopes with constant views of the Matterhorn. The route is usually done from Blauherd to Sunnegga so that most of the day is a comfortable descent. A good estimate for the active part is about 3.5–4.5 hours of walking, roughly 11.3 km, elevation gain of about 265 m, and descent of about 540 m. Formally, this day can be considered high difficulty for this tour because of the altitude, length, and rocky sections, but the trail itself remains suitable for a regular traveler without special equipment: it is a marked, popular route with no glaciers, ropes, or technical climbing. Along the way are Lakes Stellisee, Grindjisee, Grünsee, Moosjisee, and Leisee: some offer perfect reflections of the Matterhorn, others have a wilder and calmer atmosphere, and the finish at Leisee is excellent for a long break before descending. It is best to start in the morning so you can comfortably catch the lifts and complete the route before afternoon thunderstorms. In the July–September season, the trail is usually in its best condition, but after fresh snowfall, heavy rain, or fog, visibility can deteriorate sharply and some sections may become slippery. It is also useful to check in advance the operation of the Sunnegga funicular and the lift to Blauherd, because weather and technical changes are possible in the Alps.
