The Pic de Bure via Combe Ratin Trail features diverse and demanding terrain. Expect steep ascents, often on unstable scree slopes, particularly within the Combe Ratin itself. You'll also encounter grassy sections, rocky paths, and a unique 'moon-like' plateau. Some parts, like the Pas de la Fenêtre, include wired sections and can be aerial, requiring sure-footedness and alpine experience.
This trail offers extraordinary scenery. Key highlights include the unique, almost lunar landscape of the Plateau de Bure, home to the IRAM radio astronomy observatory. From the summit of Pic de Bure, you'll be treated to exceptional panoramic views of the Écrins Massif, Southern Alps, Mont Ventoux, and other major peaks. The Combe Ratin itself is wild and spectacular, with elegant curves between high walls.
Given its challenging nature, the estimated hiking time for the Pic de Bure via Combe Ratin Trail can range from 5 to 8 hours, depending on your fitness level and pace. It's a demanding route that requires good physical condition.
The trail passes through the Réserve Biologique Intégrale du Chapitre. Within this protected area, dogs are permitted but must be kept on a leash at all times to protect the local wildlife and environment.
The best time to hike the Pic de Bure via Combe Ratin Trail is typically during the warmer months, from late spring to early autumn, when the snow has melted and weather conditions are more stable. Always choose a clear day to fully appreciate the panoramic views, and be aware that the mountain can feel like a desert at higher altitudes, so prepare accordingly.
The trail is located within the Réserve Biologique Intégrale du Chapitre. While no specific permits or entrance fees are mentioned, there are important regulations to follow: dogs must be kept on a leash, you must stay on marked trails, and camping, bivouacking, and aerial sports are prohibited to preserve the natural environment.
While specific parking locations are not detailed, the trail typically starts from a point that allows access to the Combe Ratin. It's advisable to research the most current trailhead access points and parking options before your visit, as these can sometimes vary or have limited capacity.
Yes, sections of this route follow parts of the official GR Tour du Dévoluy, which is marked with red and yellow blazes. You may also encounter portions of the Pic de Bure trail and the Combe Ratin trail itself, along with numerous cairns guiding the way.
Given the trail's difficulty and terrain, it's crucial to bring sturdy hiking shoes with good ankle support, plenty of water (as higher altitudes can be very dry), appropriate layers for changing mountain weather, sun protection, and a map or GPS device. Alpine experience and sure-footedness are highly recommended.
No, this trail is consistently rated as 'difficult' or 'very difficult' due to its length, significant elevation gain, and challenging terrain, including scree slopes and aerial sections. It requires very good fitness, sure-footedness, and alpine experience, making it unsuitable for families with young children or beginner hikers.
The trail is in a mountainous, natural area. While specific facilities directly at the trailhead are unlikely, nearby villages or ski resorts in the Dévoluy massif, such as Superdévoluy or La Joue du Loup, would offer cafes, restaurants, and accommodation options. It's best to plan for refreshments and lodging before or after your hike in these larger hubs.
