There are 2 passages where you have to climb via a ladder construction. The first passage is the trickiest because it feels like a step is missing. Otherwise, the gorge is easy to walk for people with reasonable fitness and good sure-footedness. We walked the gorge in good weather and with no water flowing through the gorge. If it has rained recently, everything seems a bit slippier and experience with gorge walking is an advantage.

After a long section of "classic" pass, we suddenly find ourselves on the side of a cliff with a majestic view 😍. The valley is not very long but magnificent. Many nooks and crannies to stop and take a photo.

The Col road leads to Barbières, winding through the sublime landscapes of the Vercors. Upon reaching the village, after a gentle but winding climb, the view opens up onto majestic mountains and green valleys. Dotted with meadows and forests, this route is ideal for cyclists in search of natural beauty. The village of Barbières, nestled at the foot of the cliffs, offers a picturesque setting, perfect for a well-deserved break.

This gravel segment is a real must-see. Probably one of the most beautiful sections in the region. Recommended in 700x40 and more in the direction of the ascent than the descent. In this way it allows you to penetrate the Vercors as it deserves, with poetry! Starting from the gorges of Omblèze, and their waterfalls, to the gates of the Vercors in Léoncel.

In the Drôme section of the Vercors massif, a spectacular road runs for nearly 4 kilometres along the impressive limestone escarpments. This is the Combe Laval road, which connects Saint-Jean-en-Royans to the Col de la Machine. Opened in 1898, it was originally used to transport wood but soon became a tourist attraction. Today, the Combe Laval road is a must-see in the region, due to its location in the centre of a majestic cirque, with breathtaking scenery. The continuous alternation between tunnels and open-air sections leaves no room for monotony. It is also dotted with dizzying viewing points offering splendid views of the Royan landscape.

The canyon-like environments, particularly in the Combe d'Oyans, are known for their challenging nature, often described as "rando-vertige" (vertigo hikes). You can expect steep slopes, escarpments, and rock ledges. Some paths feature smooth, slippery rocks, with assistance provided by sealed chains and fixed ropes. For example, the highlight simply named Canyon is described as having difficult and slippery sections, requiring appropriate footwear.
While many trails in the Combe d'Oyans are challenging with vertiginous paths, some sections might be suitable for families with older children who are experienced hikers and comfortable with heights. Always check specific route descriptions for difficulty and ensure everyone has appropriate footwear and is prepared for potentially slippery or steep sections. The scenic drives like Combe Laval Cirque can be enjoyed by all ages from the comfort of a vehicle, with opportunities for short, easier walks at viewpoints.

Given the challenging and often slippery terrain, especially in areas like the Combe d'Oyans and the highlight simply named Canyon, appropriate footwear is essential. Sturdy hiking boots with good ankle support and excellent grip are highly recommended. Be prepared for wet conditions, as some paths may involve walking through water or over damp, smooth rocks.
Many of the trails in the Combe d'Oyans and surrounding areas can be incorporated into circular routes, allowing you to experience diverse landscapes. For instance, the scenic drives like Combe Laval Cirque are often part of larger loops popular with cyclists, which can also be adapted for hiking.
