The hike starts on Solalex plateau, located at the end of a valley basin at the foot of the Diablerets massif and the impressive Miroir d'Argentine: this shimmering silver rock wall, literally smooth as a mirror, is a classic for all mountaineers. It is actually a fossilised coral reef, once submerged in the primeval Tethys Sea (200 million years ago) – as plenty of fossils attest. This is one of Switzerland's most famous climbing walls, spanning multiple rope lengths.

You then hike uphill towards Anzeinde on mostly broad paths. If you listen carefully, you'll hear the marmots whistling as you arrive. Farmed since the 13th century, this Alpine meadow is located on a broad high plain above the tree line. From here, you have a stunning view of the steep rock faces beneath the glaciated Diablerets group of mountains. Look up to admire the Alpine view – and from here on, the hike itself becomes increasingly Alpine. It takes you to Col des Essets pass, which you cross.

After descending through a valley to Alp La Vare, the route climbs again via Sur Champ to La Motte. You need to be sure-footed on this section, which is more challenging in a couple of places. On reaching the top, an enchanting view of the Rhone and Lake Geneva opens up. Then comes a somewhat steeper descent to Solalex, where the hike started. At one difficult point, the path is secured with chains but otherwise, the going is good. On returning, you've certainly earned a break: enjoy gazing for one last time at the sheer rock wall, still bathed in shadow.
