Top Sites: Darwin Island (Tower Rock, Darwin's Arch, the Channel) and Wolf Island(Anchorage, Rock, Hat Island)
Water Temp/Gear to Take: around 70F in May so take a 7mm, hood for cold spots. Recommend still camera with strobes and video with lights as lots of big stuff to see. Amazing schools of Hammerheads, Eagle Rays, reef sharks, turtles, manta rays. Lots of current so signaling/safety gear is a must in strong conditions.
Places to Go: Charles Darwin Research Center, San Cristobal Island, Santa Cruz. See the Blue Footed Boobie (Bird), Giant Tortoises, Sea Iguanas, Sea Lions, Dolphins, Turtles, etc etc.
