Very nice hike. It was quite crowded today. Contrary to what’s written in the description, I didn’t see any particularly risky passages

Despite the chilling photos, the Cravate passage is not very exposed as long as there are no snowfields left to block the road (you can see them from La Roche sur Foron, which is quite practical as a local). Of course you shouldn't be afraid of heights but this path can even be crossed by running! So no worries

A majestic summit resembling a pyramid from the Cenise side, the Jallouvre - or Jalouvre - is a mythical summit whose ascent, although not difficult compared to its neighbor Pointe Blanche overhanging it by 30m, remains in the memory like that of a almost epic adventure between grueling scree (on both sides), the mythical Col du Razoir (the aptly named) and the Passage de la Cravate which, in the end, poses no more problem than that when the residual snowfields have disappeared, unless that we are subject to vertigo. In summary, one of the most beautiful hikes in the area in my opinion, for which you still need to be sure-footed and in good shape, but which can be tamed quite easily. Do not miss !

Very popular spot in summer. If you have a little strength in your legs to spare, don't stop at the lake, go up to the Balafrasse pass which gives a breathtaking view of the first as well as the Aravis range and Mont Blanc.

Much more aesthetic path than the usual path, it is however not recommended in case of vertigo

A few more 300m to climb from the lake but a fairly impressive panorama of the Aravis and Mont Blanc that you can't see from below. The climb is steep at the end but nothing very difficult (except perhaps the crossing to the summit cairn)

Mountaineering around Marnaz is primarily suited for experienced individuals. The region features 11 difficult routes and 4 moderate routes, with no easy options available. This indicates a focus on challenging alpine ascents and rocky terrain.
The mountaineering routes in Marnaz are generally quite demanding, with most classified as 'difficult' and no 'easy' routes available. Therefore, they are not typically recommended for families with young children or those seeking very gentle trails. These routes often involve significant elevation gain and technical sections.
The best time for mountaineering in the Marnaz region is typically from late spring to early autumn (June to September). During these months, snow has usually melted from higher elevations, and weather conditions are more stable, offering clearer paths and safer ascents. Always check local weather forecasts and trail conditions before heading out.
Given the challenging nature of the routes, essential gear includes sturdy mountaineering boots, appropriate layered clothing for varying alpine conditions, a helmet, harness, and via ferrata set if tackling routes like the Via Ferrata loop from Col de la Colombière. Always carry sufficient water, high-energy snacks, a map, compass or GPS, and a first-aid kit.
Yes, many of the mountaineering routes around Marnaz are designed as loops, allowing you to start and finish at the same point. Examples include the Petit Môle – Le Môle loop from Ayse and the View of Lac de Lessy – Lac de Lessy loop from Le Chinaillon, which offer varied terrain and panoramic views.
The region offers stunning natural beauty. Many routes provide views of high-altitude lakes, such as Lessy lake, or traverse notable mountain passes like Col de la Colombière. These features are often integral to the mountaineering experience, offering picturesque stops and challenging terrain.

Generally, no specific permits are required for day mountaineering trips on established trails in the Marnaz area.

Yes, many popular starting points for mountaineering routes, such as Col de la Colombière or Le Chinaillon, typically offer designated parking areas. It's recommended to arrive early during peak season to secure a spot, especially for longer routes.
For a challenging route that might offer a slightly quieter experience compared to the most popular trails, consider the Col de Balafrasse loop from Col de la Colombière. This difficult 6.8 km route involves significant elevation and offers stunning views away from the busiest spots.
The alpine environment around Marnaz is home to various wildlife. Keep an eye out for chamois and ibex on rocky slopes, marmots in higher meadows, and various bird species, including eagles and vultures, soaring overhead. Respect their habitat by maintaining a safe distance and not disturbing them.
While the region is stunning in winter, mountaineering during this season requires specialized skills, equipment (such as snowshoes, crampons, and ice axes), and a thorough understanding of avalanche risks. Many routes become significantly more challenging and dangerous due to snow and ice. It is highly recommended to go with an experienced guide or only attempt routes you are very familiar with and well-equipped for.
