The Revillagigedos Islands (also known as the Socorro Islands) are a small, isolated island group about 250 miles SE of Cabo San Lucas, Baja California Sur. Here are some photos of my dive trip there in April 2005 with the excellent dive boat Nautilus Explorer, based in Vancouver, BC. The islands are a Biosphere Reserve and are known in the diving world as one of the best places on earth to see and interact with giant mantas. It didn't disappoint!
