To the Arêtes des Ombrintses under the Rothorn is a 7.5 mile moderately trafficked loop trail located near the city of Anniviers that offers the chance to see wildlife and is rated as difficult. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible from April until September.
A more adventurous hike to the Aretes des Ombrintses which lies just under the Rothorn (2998m) When arriving in Chandolin you can park your car above the tourist office. This is also the starting point of this hike. The parking spots are not free so don't forget to fill the meter. At the tourist office you'll find a bunch of yellow signs, we start with following the path to Lac Noir. this path leads us immediately on a ski slope. When crossing the big path we turn right along this path and after 50m turn left, it is marked with a backpacker sign. This small path leads to the first alp or 'Le Premiere Alpage de Chandolin'. Here they make local cheese and for the kids it's also a mini farm in the summer. But we are here to hike, so we take the backpackers path above the alpage to 'La Grande Remointse', the second alp of Chandolin. We go through the farm as we arrive, following the backpackers path and the white-red-white markings. This path will lead us to Lac Noir and when you arrive early here you can see some wildlife too. We do not go to the lake itself but it is optional, it is a good resting point but ideally its better to rest at the summit of Aretes des Ombrintses. So at the crossing point with Lac Noir we follow the big road to the right and keep following it until we reach the end of it. You'll notice that the path gets rougher with more loos rocks. And that's the moment where the path changes abruptly to a big debris field with no more path visible. The key here is to look good on the GPS device and look for big red sticks that stand in the rocks. Those are the key to a good crossing. But be careful, not every stone is steady as a rock! When climbing over all these rocks, do look behind you while you'll get an amazing view on the Illhorn mountain. Once the debris field has been crossed we have a path again. Still rocky but better than the debris field. The summit is not far away anymore. Once reached you'll get a view on the other side of Aretes des Ombrintses with view on the Rothorn and Bella Tolla as the nearest mountains, the Torneo mountain chain a bit further and of course the 5 +4000m mountains Cervin, Ober Gabelhorn, Dent Blanche, Grand Cornier, Zinal Rothorn. From the summit we walk down the ski slope in the direction of Cabane de la Bella Tolla, this is a neat cabane with a very nice view over the Val d'Anniviers. Definitely worth a stop before heading back to Chandolin. At the Cabane we head to Par. di Modxes, a crossing point between Tignousa, the Cabane and the path to Chandolin. In local terms the path from Par. di Modxes is called "Chemin dificile" or difficult path. Not that it is difficult but it's not an average path. After that, we can see the Chandolin village where we started.
