La Grande Clue: A Balcony Road in France

# Passage de la Grande Clue

Tucked away in the Alpes-Maritimes, you'll find this short but seriously scenic balcony road that's become something of a legend among French road enthusiasts. Located just north of the stunning Gorge du Cians in the Provence-Alpes-Côte d'Azur region, it sits within the Mercantour National Park in southeastern France.

The D-28 stretches for about 500 meters of pure drama. What makes it so special? Imagine towering walls of deep crimson rock carved right through the mountains by the River Cians, creating this jaw-dropping gorge that'll have you reaching for your camera at every turn. The exposed red rock formations are absolutely stunning, complemented by a rushing stream below dotted with tiny waterfalls and natural sculptures that look almost otherworldly.

Here's the thing though—this little stretch of asphalt has quite the reputation. Landslides, rockfalls, and mudslides are real hazards that can pop up without warning, sometimes completely blocking sections of the road. You'll often spot fallen rocks scattered across the pavement, which is exactly why this thrilling route was eventually closed to vehicle traffic and bypassed by the Tunnel de La Grande Clue (a 230-meter tunnel).

But don't be discouraged! The area remains phenomenally beautiful, and if you're curious about similar landscapes, La Petite Clue—another equally breathtaking gorge—sits just to the south. It's the kind of place that reminds you why these Alpine regions are so captivating.
