Green Spain has finally emerged from a miserable winter into a glorious if unreliable springtime, so it’s time to get out and enjoy the region’s natural beauty.
The northern coastal strip of Spain consisting of Galicia, Asturias, Cantabria and the Basque Region has the best outdoor and underground adventures the country has to offer. Its combination of scenic hikes and extensive caves is thanks to the predominance of karst, a type of stone the weathers quickly with water. As you can see from the picture above, rain turns exposed karst into strange, picturesque shapes. When water flows underground it carves out long caves.
One of the best places to see this at work is the Parque Natural de Collados del Asón in Cantabria. Less than an hour’s drive from both Santander and Bilbao, this 11,700-acre natural park is cut through by the Asón River and several smaller streams. Those and the frequent rainfall have scoured the terrain into a series of gorges and cliffs. A network of trails provides lowland rambles past traditional farmhouses and challenging climbs up to rugged and snowy peaks. The dark mouths of several caves beckon to you from the trailside, but these aren’t places to explore without training and preparation.
The weather was glorious the day we went. When you have a fine day here in the north, you get outside. Luckily, you don’t need good weather to get some exercise. The next time I went out we were pelted with a chilly northern rain, perfect conditions to explore Green Spain’s other outdoor attractions – its caves.
Caving is big here, with several organizations and adventure travel companies ready to show you the ropes. And for many caves, ropes are what you’ll need. As water cuts through the stone, it often finds fissures and plunges downwards, gradually widening them into vertical shafts. Rappelling into Stygian darkness is one of the best thrills caving has to offer.
One cave where you don’t actually need ropes is Cotera Cave, not far from the famous prehistoric painted cave of Altamira, 20 minute’s drive outside of Santander. The entrance isn’t terribly inviting – an almost invisible trail snarled with brambles leads to a low opening where cows take shelter from the rain. Cows, being cows, have left more than their hoof prints behind.

Cotera is a wet cave. For much of the route we sloshed through ankle-deep water as more dripped on us from above. This action creates the formations that make caves so alluring. Cotera appears to be a fairly young cave since there aren’t many large stalactites or stalagmites. Instead, we had baby formations in the form of soda straws, which with enough water leaving mineral deposits on them will eventually grow into stalactites.
At times, the cave narrowed down into tiny crawlspaces we had to worm our way through. Often these shafts took lung-crushing right turns or plunged down at 45 degrees so that we scooted down slick clay into a welcoming puddle. In this sport a “taste of adventure” tastes like wet clay, and the grit gets stuck between your teeth.
Once the cave had covered us in grime, it decided to wash us off by making us crawl along an underground stream with a low roof. There was no choice but to get on our hands and knees and splash trough chilly water. We spotted a couple of underwater passageways leading off into the unknown.
We let them stay a mystery. Cave diving – a combination of spelunking and scuba diving – is extremely dangerous and best left for the truly crazy.
