The waterfall is designated as a Natural Monument by the Principality of Asturias.
The drop of the main waterfall, the Tabayón de Firbia, is roughly 30 meters high.
The site hosts three distinct falls: the main Tabayón, La Ulloa, and Firbia, accessible via a specific trail.
The surrounding landscape is shaped by the presence of significant quartzite crags.
The area is home to specialized riverbank flora including alder and ash trees.
The Tabayón de Firbia is a waterfall located near the village of Oneta in the Villayón council of Asturias, Spain. It drops approximately 30 meters into a pool, forming part of the Oneta waterfall complex which includes three distinct falls along the same river. The area is a protected Natural Monument, characterized by its lush valley ecosystem and riverbank vegetation. Access requires traversing a rural landscape through beech, oak, and chestnut woodlands. The waterfall is fed by the Firbia stream, a tributary of the Navia River. The terrain consists of steep slopes and quartzite formations typical of the local geology.
The rocky outcrop directly facing the base of the main waterfall provides the most comprehensive view of the drop.
Wear sturdy, waterproof hiking boots as the path can be muddy and slippery throughout the year.
Bring a light waterproof jacket, as the mist from the waterfall creates high humidity near the base.
Ensure your mobile device is fully charged or carry a paper map, as cellular reception is inconsistent in the valley.
Do not attempt the trail in heavy rain or immediately after major storms, as the path becomes dangerously slick.
Carry out all trash; maintain quiet to avoid disturbing local wildlife; stay strictly on marked paths to prevent erosion.
