Where is Brasina?extreme

Where is Brasina?

🌍 Bosnia

Brasina Peak is an absolute must-do for off-road adventurers in Bosnia and Herzegovina, towering at 1,873m (6,145ft)! This peak is nestled in the Herzegovina-Neretva Canton, a stone's throw from Mostar. Starting in Mostar at just 177m, the 23.4 km (14.54 miles) journey gains a whopping 1,696 meters in elevation. That's an average gradient of 7.24%, with some sections hitting a steep 14%! The road starts as pavement, but quickly deteriorates. Be prepared for a fully unpaved, rocky, loose gravel track, winding along some serious drop-offs! It's narrow, barely wide enough for two cars. Expect some seriously steep inclines and about 24 hairpin turns. An old military road, the route has some cool history, including the remains of Austro-Hungarian fortresses and a former military base at the top. The views? Unreal. Brasina overlooks Mostar and, on a clear day, you can see all of Herzegovina and even the Adriatic Sea in the distance. Plus, stunning mountain vistas of Prenj, Čvrsnica, and more! **Important note**: Stick to the road, there are dangerous minefields. This road is generally closed from November to May due to heavy snow, avalanches, and icy conditions. Water is scarce, so pack plenty, especially in summer.

Dosso Alto Pass: enjoy a road among the clouds

🇮🇹 Italy

# Passo del Dosso Alto: Italy's Hidden Alpine Adventure Want to experience one of the Alps' most wild and raw mountain roads? The Anfo Ridge Road takes you up to Passo del Dosso Alto, perched at 1,727m (5,666ft) in Brescia, Lombardy. This isn't your typical smooth Alpine crossing—it's the real deal. This 20.1km (12.48-mile) east-west route from Anfo to Passo del Maniva is basically unpaved adventure. You'll navigate four short unlit tunnels (newer ones added in 2010 to bypass the tightest squeezes) along what's been a mountain passage since Roman times. The road had serious trouble—it was actually closed for six years after a landslide, but finally reopened in 2009. Today, it's still gloriously rough around the edges, with plenty of dust, loose stones, and character. Fair warning: this route demands respect. You're dealing with rock fall risks, sheer unprotected drops, hairpin turns, and a surface that's basically a potholed, rocky obstacle course. The speed limit caps out at 20 km/h, and vehicles wider than 2.5m or taller than 3.2m aren't even allowed. With grades hitting 12 percent and minimal maintenance, it stays gloriously untamed. You'll climb four mountain passes: Passo Baremone (1,450m), Passo della Spina (1,521m), Passo della Berga (1,527m), and the main event at Passo del Dosso Alto. The scenery? Absolutely stunning. The driving conditions? Intensely challenging. Summer months (June through October) are your window, though heavy rains can shut it down anytime.

Where is Refuge du Plan du Lac?hard

Where is Refuge du Plan du Lac?

🇫🇷 France

Okay, picture this: you're in the French Alps, Savoie to be exact, heading to Refuge du Plan du Lac. This mountain hut sits way up high at 2,370m (7,775ft) inside Vanoise National Park. The drive starts in Val-Cenis, winding for 15.1 km (9.38 miles). Most of the road's paved, but get ready for some steep climbs, hairpin turns, and a few bumps along the way. The views just keep getting better and better as you ascend! Now, heads up, after the parking lot for Refuge - L'auberge de Bellecombe, only authorized vehicles are allowed. Unless you have permission from Vanoise National Park, you'll need to park and hike the final stretch. Bikes aren't even allowed. But trust me, the views are worth it. The first bit's steep, zigzagging through a sparse forest with killer views of the valley below. Once you're at the refuge, BAM! Panoramic views of Pointe de la Réchasse, Dent Parachée, Grande Casse, and glaciers galore. Don't forget to check out Chapelle Saint-Barthélemy just beyond the refuge. It's a cute little chapel at 2,284m!
