# Semnoz (Crêt de Chatillon): A Classic Alpine Climb
Perched at 1,660 meters (5,446 feet) in France's Bauges range in Haute-Savoie, Semnoz—also known as Crêt de Chatillon—is one of those legendary Alpine passes that actually lived up to the hype. The road up (D41) is fully paved, which is always a relief, but don't let that fool you—some sections hit a gnarly 11.4% grade that'll definitely keep you honest on the pedals or behind the wheel.
The pass has serious cycling credentials too; it's been tackled by Tour de France riders over the years. At the summit, there's a modest ski station where you can grab a bite and soak in the views.
**Getting to the top? You've got options:**
Coming from **Quintal** is the shortest but spiciest route: 11.3 km with 922 meters of elevation gain averaging 8.2%. If you're starting from **Col de Leschaux**, it's a more relaxed 13.4 km climb at 5.7% gradient, gaining 763 meters. From **Annecy**, you're looking at 17.4 km and 1,212 meters of elevation gain (averaging 7%), which hits the sweet spot for most climbers. Finally, the **St Jorioz** approach stretches to 22.78 km with 1,202 meters of gain at a mellow 5.2%—perfect if you want to take your time and savor the Alpine scenery.
No matter which route you choose, you're in for stunning mountain views and a climb that'll feel rewarding from start to finish.

moderateHow to get to Pico de las Nieves?
🇪🇸 Spain
Hey fellow travelers! Let me tell you about this insane road trip to Pico de las Nieves, a peak chilling at 1,942m (6,371ft) on Gran Canaria in the Canary Islands. It's the island's second-highest point, and the drive? Epic! You'll find this gem, also known as GC-134, smack-dab in the island's center. The road's paved the whole way, even though it leads to a military base (don't worry, you're allowed!). Starting from the GC-130, it's a short but intense 1.4 km (0.86 miles) climb. Get ready for some steep sections hitting a max gradient of 10%—hold on tight! The tippy-top is mostly a military zone, complete with a giant radar that looks like a soccer ball, so you can't explore all of it. But the real prize is the natural viewpoint! On a clear day, you can see half the island and even catch a glimpse of Tenerife's majestic Pico del Teide. Seriously, the view is unreal. Up there, you're practically touching the sky and the views of the Teide peak are magical. Heads up, though: trade winds can bring clouds that totally cover the summit, so try to avoid windy or rainy days. Trust me, you don't want to miss those views!
moderateTraversing the international Bielsa Tunnel in the Pyrenees
🇫🇷 France
# Tunel Bielsa-Aragnouet: A High-Alpine Crossing Ready for some serious Pyrenean adventure? The Tunel Bielsa-Aragnouet is your ticket to crossing from Spain into France at a breathtaking 1,820m elevation. This 3.07km tunnel has been connecting the charming villages of Bielsa (Spain) and Aragnouet (France) since 1976, and it's completely toll-free. **The Spanish Approach** Coming from the Spanish side? You'll take the A138, a fully paved road that starts in Salinas and climbs 21km with 1,028m of elevation gain (averaging 4.9%). It's a steady, manageable ascent that rewards you with stunning mountain vistas. **The French Approach** The French side tells a different story. The D173 from Saint Lary Soulan is 18.93km long with 1,000m of elevation gain (5.3% average), but heads up—the road surface isn't quite as pristine as the Spanish side. Watch out for that gnarly 11.8% maximum gradient in places. **What to Know Before You Go** The tunnel itself is two lanes and mostly straightforward for cars, though trucks and buses alternate directions (plus there's a 4.3m height restriction). The best part? This route stays open year-round, though you might face 7-10 days of winter closures when avalanche risk gets serious. Just avoid the tunnel if you're hauling hazardous materials.
