Expedition cruising in the Galapagos is very different than most cruises. The entire area is a closely managed national park, and you will not set foot on the ground, nor snorkel, without supervision by a Ecuadorian certified guide. There is no walking around on your own, Groups stay together with a guide at all times. Please be sure you are in good physical condition, able to board a zodiac that is moving in swells, climb a steep staircase, and walk at least 1/2 mile on uneven terrain.
