Although we have no sea, there is no shortage of water in the Sierra de Guara. Throughout the Natural Park, the rivers have patiently carved out ravines, pools and natural swimming holes of wild beauty. Some are well-known and well-maintained, whilst others lie hidden amongst rock faces and pine forests, accessible only to those who know the terrain well.
The best-known natural pools: between Alquézar and Bierge
The Alquézar area is one of the most popular gateways to the Natural Park. There, the River Vero forms several pools near the village, which are accessible from the town centre and linked to the well-known Ruta de las Pasarelas. In high season, it’s best to get there early to enjoy them in peace. Also near Alquézar, in Pozán de Vero, lies the Azud de Abajo, a turquoise pool formed at the foot of an old irrigation channel which has become famous for its photogenic beauty.
A little further south, on the River Alcanadre, the Salto de Bierge remains one of the most popular spots in the Sierra de Guara. This old dam, which has been converted into a bathing area, offers space for swimming or relaxing. In summer, a small entrance fee is charged to help preserve the environment.
Rodellar and the Mascún: nature at its finest
Rodellar is a paradise for climbing enthusiasts, but it also boasts some of the most spectacular natural pools in the mountains. The Mascún Gorge, carved out by the River Alcanadre, forms pools of water amongst limestone rocks and vertical cliffs. Reaching them requires a walk from the village, but the reward lies in the beauty of the landscape and the tranquillity of the surroundings.
The River Vero and its hidden corners
Further on beyond Alquézar, the Vero continues its course towards the south, leaving in its wake path spots where to cool off. One of the most peaceful is near to Lecina, where the river forms a pool little known, perfect for those who seek to escape from the crowds.

Hidden pools in the northern part of the park
On the northern slope of the park, between the Belsué and Nocito valleys, lie some of the least-known and most beautiful natural pools in the Sierra de Guara. La Carruaca, near Lusera, is a short gorge with a pool at the end that’s ideal for a swim after a hike. Not far from there, the Gorgas del Romeral offer a water walk amongst curious rock formations, perfect for visiting with children or during the cooler months.
In the Bara area, also within the park, we find the Gorga Negra, a deep pool in the River Used that marks the start of one of Guara’s most iconic gorges: the Gorgas Negras. And not far away, the Salto de la Tosca rounds off the route with a large pool and a five-metre waterfall surrounded by vegetation.
And what’s more… the salt flats of Naval
Although they are not natural pools, the Naval salt flats deserve a special mention. These saltwater pools, situated on the edge of the village, are fed by a saltwater spring and form part of the traditional landscape of the Sierra. With five pools in total, they offer a bathing experience quite different from the rest of the Sierra de Guara, but just as stunning. There is an admission charge and the facilities are well maintained.
These spots are just a small part of the mosaic of natural pools and swimming areas hidden within the Natural Park. If you’re looking for more secluded spots, remember: ask the locals. No one knows the area better. Take the opportunity to chat with them, listen to their recommendations, and discover the Sierra de Guara beyond what you see on social media. Stay for a few days, enjoy local produce, book reliable services if you’re looking for an adventure, and above all, leave the place better than you found it. Remember that you’re in a protected environment.
