The route in detail
The loop is usually walked clockwise from the main trailhead. The first third does most of the climbing, so settle into a slow rhythm early rather than trying to hold a flat-ground pace. The upper section is where the route earns its reputation, and it is also where weather changes fastest. The return leg is the reverse of the outward journey, which makes it easy to judge remaining time.

Tips from the trail
- Start at first light. A long day is far more pleasant when you are not racing the sunset on the descent.
- Aim for april to october for the most reliable conditions.
- Download the track to your phone before you leave. Signal is not guaranteed.
- Break the route into stages and decide your turnaround time before you set off.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- This route is long and sustained. Turn back early rather than late if the weather closes in.
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in Switzerland are reached on 112. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage is generally usable along this route, but do not rely on it as your only plan. If the weather deteriorates, descending the way you came is almost always the safer option.
What to bring
- Comfortable, broken-in hiking shoes or boots
- Weatherproof jacket
- At least 1.5 litres of water
- Trekking poles for the descent
- Offline map and compass
- Head torch and spare battery
- Extra warm layer
- Sun hat, sunglasses and high-factor sun cream
- Real food, not just snacks
Photography
Shoot the first hour after sunrise from the higher ground: the low angle picks out every ridge and the valleys still hold mist. Because it is a loop, the light changes direction as you go, so save some memory for the back half. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
