Galapagos Live-Aboards are the only way to dive the legendary northern Islands of Wolf & Darwin.  If you are even reading this, no further explanation is necessary. For others, these site are considered the best on the planet for pelagic life.  Between mid-June and November, the odds of sighting whale sharks is roughly 99%.  And hammerheads are year round, often iin groups of hundreds. 

Diving rules and regulations are undergoing further updates via the ultimate authority in the Galapagos...The Galapagos National Park, often abbreviated to simply PNG (Parque Nacional Galapagos).  Before visions of 2007 scare you away, don't worry.  This time, PNG is awarding new permits to dive Wolf & Darwin...cupos de tur navegable y buceo.  As of 2010, 14 permits are available but as of now (January 2010), there are only 4 live-aboard options until May: the Aggressors I and II, the Deep Blue and the Sky Dancer. In May, the Humboldt Explorer will make her maiden voyage.  Both the Alta and the Estrella del Mar offer seasonal (whale shark) trips to Darwin and Wolf between June and December with July through November being optimal.

It certainly appears that by 2012, live-aboards will not be allowed to include certain land visits now on itineraries as PNG tightens restrictions on sensitive sites.
