Cerro Juquel: Driving the steep 9.5% climb in Potosí, Bolivia

Deep in the Potosí Department of southwestern Bolivia lies Cerro Juquel, a mountain peak soaring to 4,612m (15,131ft). This landmark pierces the desolate Andean landscape, offering access to a communication tower via a seriously dramatic, technical road. The views? Absolutely insane – think salt flats stretching forever and stark volcanic terrain.

Your adventure kicks off near Hostal De Sal La Escondida, that cool salt hotel you'll find in the Altiplano. From there, the track claws its way up the dry, rocky mountainside of the Potosí region. It’s a land of pure isolation, sculpted by volcanic minerals and super thin air. The climb is 9.01 km (5.60 miles) long, and as you gain altitude, the ground gets looser and more technical. This is not for the faint of heart (or the 2WD).

Yep, the road to the summit is 100% unpaved. It's a narrow, rocky track demanding a 4x4 beast. The trail is super steep, featuring 19 hairpin turns that will have you gripping the wheel. These switchbacks are tight and often have significant drop-offs, so maybe skip this one if you're scared of heights. The surface is high-altitude gravel and volcanic soil, which can get slippery, especially on those ramps where the 9.5% gradient makes your engine scream.

The real challenge of Cerro Juquel is that brutal combo of steepness and altitude. Over those 9 km, you'll gain 856 meters in elevation, resulting in an average gradient of 9.5%. Up at 4,600+ meters, your engine will struggle with the lack of oxygen, seriously impacting power. Low-range gearing is a must to keep things smooth through those hairpins. The communication tower at the top is your final destination, but the real reward is that mind-blowing panorama of the desolate Potosí wilderness – a view few travelers ever witness.

Weather here is harsh and unpredictable. Even in the dry season, high winds are a constant, making steering tricky on the exposed hairpins. Temperatures plummet the moment the sun dips, often well below freezing. If you encounter any moisture, the volcanic dust transforms into a super-slippery paste, turning that 9.5% grade into a dangerous slide. Always check local conditions and pack recovery gear, extra fuel, and warm layers before ditching the salt plains.
