What type of diving do the boats offer?
There are three choices: live-aboard diveboats offering purely diving, cruises offering occasional diving (1-2 dives per day) which are often timed not to substitute the normal naturalist land visits, and shore-based dive operations (mainly on Santa Cruz) which take you on day trips. Diving is excellent in the Galapagos, but due to currents is not really for the beginner.
