Lagunas de Neila, an iconic Vuelta a España climb

# Lagunas de Neila

Tucked away in Burgos province in Spain's Castile and León region, Lagunas de Neila is a stunning high-altitude glacial lake sitting at 1,873 meters (6,145 feet). Fair warning: you're in for quite the climb to get there.

The paved road winds its way up to this gem within the Lagunas Glaciares de Neila national park, but "narrow" and "steep" don't even begin to cover it. We're talking sections that max out at a teeth-gritting 17% gradient. It's definitely doable, but you'll feel every meter of elevation gain.

Winter weather is the real wildcard here. The road can shut down without warning between December and March when snow and ice take over. Time your visit accordingly, and you'll be rewarded with incredible photo ops at every turn.

Here's the thing: the last 1.3 kilometers are off-limits to cars. You'll park at the parking de las Lagunas de Neila lot and hoof it the final stretch on foot—but trust us, the scenery makes it worth the walk.

The climb is legendary enough that the Spanish Vuelta cycling race has tackled it. If you're coming up from the BU-822 road, you're looking at a 4.3-kilometer ascent that gains 466 meters of elevation. That works out to an average gradient of about 10.8%, though those steep sections will test your nerve and your brakes.
