This circuit below Les Lachellets typically takes around 5 hours to complete. This estimate is for the 13.6-kilometer route with an elevation gain of 700 meters.
The terrain is quite varied. You'll encounter natural paths, asphalt, paved sections, and unpaved stretches, as well as gravel. The route includes dedicated hiking paths, roads, and mountain hiking paths, navigating through pastures and crossing several torrent gullies. Around the Moiry reservoir, the path is generally wide and well-marked.
Hikers are treated to dramatic alpine scenery. A major highlight is the Lake Moiry with its striking turquoise-blue waters and the majestic Moiry Dam. You'll also see the wild Val de Moiry, the sparkling Moiry glacier, and potentially Lac du Louché and the small lake of Bayenna. The trail offers continuous, expansive views as it maintains an average altitude of 2500 meters.
The historical village of Grimentz serves as a charming starting point for this hike. While the research doesn't specify parking in Grimentz, it's a common access point for the region. For the Moiry Dam area itself, there is parking available near the dam crest.
The trail research does not explicitly state whether dogs are allowed or if there are specific leash rules. However, many alpine trails in Switzerland permit dogs, often requiring them to be on a leash, especially in areas with livestock or wildlife. It's always best to check local regulations or signage upon arrival.
The best time to hike this circuit is typically during the warmer months when the alpine paths are clear of snow. Given its altitude, the trail is usually accessible from late spring through early autumn. Winter hiking in the Moiry Valley would be a different experience, requiring specialized gear and knowledge.
There is no mention of permits or entrance fees required for hiking this specific circuit. Access to the Moiry Dam area and the surrounding trails is generally open to the public.
Yes, there is a restaurant located near the Moiry Dam crest. It features a sun terrace, offering views of the reservoir, making it a good spot for a break or a meal during your hike.
This circuit is generally considered a moderate hike, requiring good fitness and sure-footedness. While some paths are pleasant, it aligns with a SAC (Swiss Alpine Club) rating of 2-3. This suggests it might be challenging for very young children or those without prior hiking experience. Families with older, experienced children who are accustomed to alpine conditions might find it suitable.
For this moderate alpine hike, you should bring sturdy hiking shoes, as some sections require sure-footedness. Layered clothing is advisable due to changing mountain weather. Don't forget water, snacks, sun protection (hat, sunglasses, sunscreen), and a map or GPS device. Trekking poles can also be helpful on varied terrain.
Yes, the route also passes through sections of the Chamonix-Zermatt High-Level Walker's route and the Tour du Cervin, among others.
