The Bufones de Pría are natural blowholes in the limestone cliffs about 8 km east of Llanes, where the Atlantic waves, channelled through underground caves, burst upward through holes in the rock in spectacular geysers of spray and sound. In rough weather, the effect is extraordinary — the ground trembles, the spray reaches considerable heights, and the roar of compressed air is audible from a distance.
The site is accessed from the village of Pría along a well-signed path across the cliff-top meadows. The walk from the parking area takes about 15 minutes and brings you to a roped-off viewing area at the cliff edge. Do not go closer than the barriers — the edges are undercut and the ground can give way. The Atlas Obscura entry for the similar Bufones de Arenillas to the west confirms how dramatically the coastline behaves in storms. This stretch of the Asturian coast is one of the most geologically active in Spain, and the blowholes are its most spectacular feature.
A car is needed to reach Pría, or a taxi from Llanes.
