The best diving available from Cabo San Lucas, bar none, is 250 miles away near Socorro, the largest of four islands in the Revillagigedos chain. The 112' live-aboard dive ship Solmar V offers extended, and expensive, 9 to 11 day trips from November through June, with diving, stateroom accommodations and all meals included. The abundance of marine life found around this island chain is staggering, and includes enormous schools of giant manta rays, as well as dolphins, sharks and other large pelagic species. (Shark lovers may also want to book passage during August, September and October, when the Solmar V operates out of Ensenada, and offers cage diving with great white sharks near Isla Guadalupe, 150 miles offshore.) For those interested in local dives around Cabo San Lucas before departure, Solmar V passengers have access to special rates at Amigos del Mar.
