An old military road to Col de La Buffere in the Alps

# Col de Buffère

Perched at a seriously impressive 2,431 meters (7,975 feet) above sea level, Col de Buffère sits in the Hautes-Alpes department of southeastern France, right in the heart of the Provence-Alpes-Côte d'Azur region.

Built between 1902 and 1907 as a military route, this pass has some serious historical clout. At the summit, you'll spot remnants of World War II fortifications—part of the Ouvrage Col de Buffere from the Maginot Line. While the original plans included more combat blocks, many were never finished, adding an intriguing sense of incompleteness to the site.

Now, here's the real deal: the climb up via the Piste du Col de La Buffere is absolutely gorgeous but seriously demanding. We're talking completely unpaved terrain with gravel and rocky sections throughout. Some stretches hit gradients of 20%, so a 4x4 is pretty much essential if you're thinking of tackling this beast. The 5.1-kilometer (3.16-mile) ascent gains 314 meters with an average gradient of 6.15%—starting from the paved D234T below.

Fair warning: Alpine conditions mean the road shuts down from late October through late June or early July. Also, once you get near the summit, private vehicles are barred from the final stretch. It's a protective measure for this fragile landscape and honestly makes sense given the narrow passages and heart-stopping drop-offs.

Nestled within Écrins National Park, this route rewards your effort with stunning panoramic views of the surrounding peaks. Mix in the historical military structures, and you've got an adventure that's equal parts natural beauty and fascinating history.
