Port de Lers

# Port de Lers: A Pyrenean Gem Worth the Climb

Nestled in the French Pyrenees at 1,517 meters (4,977 feet), the Port de Lers is a stunning high mountain pass that'll make any road tripper's heart sing. Located in Ariège, this beauty is also known as Port de l'Hers or Port de Massat, and it's been tough enough to feature in the Tour de France multiple times.

The D18 is a fully paved route that connects three charming communities—Aulus-les-Bains to the west, Massat to the north, and Vicdessos to the east—with plenty of hairpin turns to keep things interesting. Fair warning though: you'll encounter some seriously steep sections (think double-digit gradients), so bring your A-game.

You've got two solid options for tackling this climb. Coming from Vicdessos is the shorter but spicier route at 11.5 km with 807 meters of elevation gain and some gnarly 10.9% stretches. If you prefer a steadier pace, head up from Massat's 16.6 km approach with 868 meters of elevation gain and more manageable 5.2% average grades (though the steepest bits still hit 8.9%).

Here's the best part: this is a year-round pass, so you can chase it in any season. Just keep in mind that winter can throw some curveballs with temporary closures, so check conditions before you go. About 3.8 km from the summit, you'll spot a junction with the Col d'Agnes climb if you're feeling extra adventurous.
