We just got back from a wonderful week on the Isabella II. She can accomodate a maximum of 40 Passagiere but, with three excellent naturalists on board, you never feel part of a herd when hiking oder snorkling. They also have a glass bottom boat for people who want to get themselves wet but who want to see fish, turtles and sealions swimming. In addition, there are several oportunities for kayaking. The boat covers an extensive itinerary including North Seymour Island, Hood Island (Gardner Bay and Punta Suarez), Floreana (Point Cormorant and Post Office Bay), Santa Cruz (Darwin Research Station and a trek to the highlands), Tower (Darwin Bay, Prince Philip's Steps), Pernandina, Isabella, James (Puerto Egas and Bartolome).

This is the nicest expedition boat I have been on. Each cabin is plain but spacious with comfortable beds, lots of storage room and a private bath. The AC can actually get a little too cold but you can turn it down with individual cabin controls. The staff checks and cleans the cabins several times a day to make beds, empty trash, and turn down service.
