Your choice of cruise may depend on which of the 24 Galápagos Islands you want to visit. The larger Galápagos ships such as the Celebrity Xpedition and the Galápagos Explorer II are generally more stable and able to sail further to some of the outlying islands.
On every cruise you will make two or three landings a day and on the larger ships there is a choice of activity levels and locations.
You will usually start and finish your cruise in Baltra. Below is a small selection of the islands you can visit.
