A nice peak with an unpronounceable name. The road from the north is covered in graffiti to encourage cyclists.

From the south, a short, steep climb on mostly good asphalt. Only the last 100 meters are a bit of gravel on the road. At the top, you're rewarded with a unique view over Finisterre.

Beautiful, spacious and easily accessible beach with only one drawback: the very busy (in June) road runs directly behind the beach.
