We don’t know how this isolated cove on the west side of Palos Verdes got it’s name, but it seems to be a favorite for scuba diving and snorkelers.
According to Franco’s Divers Maps, the cove has these highlights:
Divers enter Christmas Tree Cove via a steep dirt path at 2800 Paseo Del Mar. The underwater features mini walls and kelp, and usually the best visibility around the PV Peninsula. This is a popular game fish area, although it also features garibaldi, opaleye, treefish, and colorful bluebanded gobi. Invertebrates include: Sponges, anemones, keyhole limpets, Spanish shawls, chestnut cowries, and octopi. Good snorkeling throughout.
You can’t see any of that from the cliffs above, but you can get great views of the cove itself and the birds that inhabit the rocky coastal islets just offshore (you will need binoculars or a telephoto camera lens). Click on the image above for a 1024×768 pixel view.
