I'm going to the Galapagos in late March/early April and after the diving component of my stay (6 days/6 dives with Galapagos Diving Tours) we will be staying on Isabela for 5 days followed by staying on Santa Cruz for 5 days. The reason we're doing this is because we can't stand the idea of being on a boat the entire time and actually want to experience living on the islands and exploring them without too much restriction.
My question is: is it worth waiting to get to Santa Cruz before booking the land tours we want to do? Or should we book in advance, online? I have a feeling it might not be so hard to book tours like the following ones, once we get there (that is, we book the land tours, go diving for 6 days, then do the land tours): ISABELA: volcano, lava tunnels, etc; from SANTA CRUZ: Bartolome, North Seymour etc.
Has anyone had experience doing this? Will this be equally as expensive? Also, are last minute tour bookings likely to give us dodgy experiences? What companies would you recommend for last minute land based tours? All I can think of is Galapagos Alternative.
Heeeelppp!! And thank you so much in advance!!! I'd really appreciate any kind of information!!
