Fort de Lenlon

# Fort de Lenlon: A High-Alpine Adventure in the French Alps

Ready for a serious mountain challenge? Fort de Lenlon sits pretty at a whopping 2,508 meters (8,228 feet) in the Dauphiné region of southeastern France—and getting there is half the adventure.

The road itself is a historical gem, carved out between 1890 and 1893, and it's exactly what you'd expect from that era: rough gravel and seriously steep grades that'll test both your nerve and your vehicle's suspension. This isn't a leisurely Sunday drive—it's a genuine mountain climb that demands respect.

Here's the catch: you can only tackle this route during the summer months. The road becomes completely impassable from September through June thanks to snow and weather conditions, so timing your visit is crucial.

One more thing to know: this fortress sits within a military restricted area, which means you'll need to snag a permit before you head up. It's worth the paperwork though—the views and the sense of accomplishment once you reach the top? Absolutely worth it.
