I've been going there for many years. It's not really a beach, but a cove of fine pebbles, and swimming requires caution; there are a lot of rocks at the entrance. The surrounding area allows for several trails.

Built in 1990, this lighthouse holds the title of being the highest altitude lighthouse not only in Euskadi, but also in the Cantabrian Sea. From this point, we will also have privileged views over the Bay of Plentzia. Just below are some bunkers built in the post-war period.
