Named for the eerie green domes on a nearby power plant, this beach is extremely popular with surfers, with its consistent rights and occasional lefts. On a good surf day, arrive early if you want a spot on the sand. Although not recommended for swimmers because of the rocks, it's a great whale-watching spot in winter. The dirt road leading to the parking area is rather steep and difficult to exit. There are no facilities here, so plan accordingly. Amenities: none. Best For: surfing.
