I have a great opportunity to travel to the Galapagos islands, my sister in law is going to work on the island with the Darwin foundation and can put me up for free. I've read about Wolf & Darwin islands and can't see traveling all that way without diving there. Does anyone know if there are land based operators that travel there or is an all or nothing proposition with the live aboards? If latter is the case which ones are worth looking in to and how far in advance should I start planning? Any comments or information would be greatly appreciated.
