From Saint-Michel-les-Portes, it's about 7 km at an average gradient of 8%. The last few kilometers often reach double digits. A cruel climb if it's the last one of your day...

As pretty at the top as at the bottom, lots of ways to get to the top, accessible for all levels (not technical but lots of elevation gain depending on your starting point) but it's worth it!

The Col des Deux is not located in the Bauges Massif but in the Vercors between the Col de l’Arzelier and the Col de l’Allimas. This trilogy is well known to cyclists in the Grenoble metropolitan area.

Whether you're on gravel or mountain bike, this is a must-do for the many trails, paths, and roads that surround it. And the view of Mont-Aiguille 🤩

The Col de l’Allimas – 1352 m – is a pass located to the east of the Vercors Massif but it is an isolated pass because it does not allow you to reach the interior of the massif. On the other hand, it offers one of the most beautiful views of the massif with the remarkable peaks of the Grand Veymont and Mont Aiguille. Source: alpes4ever

Summer is ideal for exploring higher altitudes and enjoying activities around Monteynard-Avignonet Lake. Some areas, like the Gorges de la Bourne, are particularly stunning in warmer months.

While the focus is on natural monuments, the region does offer a blend of natural and historical interest. For example, the Gorges de la Bourne are not only a natural wonder but also historically significant for their role in regional transport. Though not directly in Saint-Guillaume, the nearby Saint-Guilhem-le-Désert region features the Pont du Diable, a remarkable ancient Roman bridge set within a beautiful natural gorge, showcasing how human history intertwines with the landscape.
Given the mountainous terrain and varied weather conditions, it's advisable to wear layers, even in summer. Sturdy hiking boots are essential for most trails. Depending on the season, bring waterproof outerwear, sun protection (hat, sunglasses, sunscreen), and plenty of water. For cave explorations like Grottes de Choranche, a light jacket might be useful as temperatures can be cooler underground.
Beyond the well-known sites, the Vercors Regional Natural Park holds many less-traveled paths and viewpoints. Exploring the smaller trails off the main routes can lead to serene spots and unexpected discoveries. The former glacial valley where The Boa of Vercors is located is one such gem, offering waterfalls and cliffs away from the busiest areas.
The duration of your visit can vary greatly. A quick stop at a mountain pass like Col de l'Allimas for views might take an hour. Exploring the Grottes de Choranche could take 1-2 hours. Longer hikes to summits like Grand Veymont or around Monteynard-Avignonet Lake, especially if crossing the Ebron Footbridge, can be half-day or full-day excursions. Plan according to your fitness level and desired activity.
