In the heart of Álava, one of the provinces of the Basque Country, lies a natural wonder that can transport travelers from northern Spain into landscapes reminiscent of Southeast Asia. Just forty kilometers from Vitoria-Gasteiz, there’s a trail that attracts an increasing number of hiking enthusiasts and photographers each year, especially in the fall. This natural enclave amazes visitors with its resemblance to a tropical forest, thanks to its abundant moss, cascading waterfalls, and crystal-clear water.
This is the trail along the source of the river Tobería, which begins at an underground spring in the Sierra de Entzia mountains. The water tumbles down rocky ledges, forming a whole series of picturesque waterfalls. The humid climate and dense forest surrounding the river create a unique ecosystem, where stones and tree trunks are completely covered in emerald moss, giving the area its distinctive “Asian” feel.
The route itself is not particularly challenging and is perfect for a weekend family outing. Its total length is just 2.4 kilometers, and walking the trail round-trip—including photo stops—takes no more than two hours. The path starts from the central square of the small village of Andoin, from where a forest road leads past an old mill. Blue markers serve as waypoints and will guide you straight to the cascades.
Despite being generally easy, the route includes some sections with gentle climbs, so it’s recommended to wear comfortable hiking boots. This is especially important after rain, when the ground can become slippery. In fact, it’s during wet weather or in autumn that the trail reveals its full beauty: the river swells, and the waterfalls become powerful and striking. Water flowing over limestone tuff—a porous rock—creates a mesmerizing spectacle.
As you walk along the trail, you’ll see several cascades and small pools with crystal-clear water. All this beauty is framed by beech and oak forests that turn brilliant yellow and crimson in the fall. For those looking to enjoy sweeping views, there’s an observation platform offering a stunning panorama of the entire valley and its waterfalls. The area is notable not only for its natural beauty, but also for its geological significance—the limestone tuff has long been used in the construction of many iconic buildings across Álava.
Despite being close to towns like Salvatierra and Vitoria-Gasteiz, this trail isn’t overrun by tourists. That means you can truly enjoy peace and quiet in harmony with nature. It’s important to note that the path isn’t adapted for people with limited mobility and isn’t suitable for strollers. To reach the starting point in the village of Andoin, take the A-1 highway and exit towards Asparrena. You can park your car at the lot by the local church.
Incidentally, the Basque Country, or Euskadi, is an autonomous community in northern Spain known not only for its unique culture and cuisine but also for its stunning natural landscapes. The region is part of the so-called ‘Green Spain’ thanks to its humid oceanic climate, which fosters dense forests and lush valleys. In addition to the famous beaches of the Bay of Biscay, the inland areas offer a wealth of hiking routes, revealing hidden waterfalls, mysterious forests, and mountain peaks to travelers.
