The route to the Guanga or Buanga Waterfalls, in the council of Oviedo, is an accessible and beautiful itinerary that allows you to discover one of the most attractive natural spots in the Trubia valley. The route crosses riverside woods, chestnut groves and meadows, always accompanied by the murmur of the Guanga river, which guides the walker to the spectacular waterfalls hidden among the vegetation.


The easiest access to this route is from the town of Perlavia, the ideal starting point for those looking for a simple, family-friendly option. The path starts next to the Chapel of San Antón, where the first houses are grouped together among orchards and meadows. From here, a wide track leads to La Rondera, a stretch with open views over the Trubia valley, where the mosaic of fields and wooded slopes defines the landscape.

Once past La Rondera, the path narrows and enters the forest, dominated by oak, chestnut and hazel trees, where the humidity, the murmur of the river and the shade of the trees create a serene and cool atmosphere. The path gains gradual slope, with some sections where roots and stones require a little more attention.

At a well signposted crossroads, there is a view of the Peña El Castiello, a geographical landmark in the area. This is also the junction with the path that climbs up from San Andrés, the other possible access route to the waterfalls. This alternative, although more demanding, has the advantage of being accessible by city bus from Oviedo/Uviéu, thus avoiding the use of private vehicles. However, it should be borne in mind that the climb from San Andrés involves overcoming 250 metres of unevenness in barely 1.5 kilometres, which requires good physical fitness and caution, especially in wet weather, as the terrain can be slippery.

From the confluence of the two paths, the route continues to follow the river, which begins to become more lively, with small waterfalls and pools that anticipate the arrival of the waterfalls. Suddenly, almost without warning, you discover the Guanga waterfall, which drops down several levels over the dark rock, wrapped in vegetation and moss, in a secluded corner that invites contemplation and rest.

The return is along the same path, allowing you to enjoy the details of the landscape in a different light. This route, with no great technical difficulties in its access from Perlavia, is a perfect option for those looking for a quiet, accessible walk, full of natural beauty, in the heart of the Trubia valley.

Basic tips before going into the mountains

  • Avoid approaching livestock.
  • If you find mastiffs protecting livestock, do not approach them, do not pet them and do not feed them. Do not allow them to follow you or stray from their herd. They are working.
  • If you go with a dog, always keep it on a leash.
  • Don't leave a trail. Collect all your waste, including organic waste. Nature is not a dumping ground.
  • Act with prudence. Plan your route well, take everything you need and make sure it is adapted to your physical capacity.
