2. Lindblad Expeditions
Lindblad Expeditions specialize in the Galapagos, South Pacific, Indian Ocean, Antarctica, Greenland and the Arctic Circle. They’re partnered with National Geographic so much of what they do is considered ecologically focused “soft-adventure”. Their vessels hold just 28 to 148 passengers. Expect scientific tools for checking out sea life, knowledgeable expedition leaders as well as spa services (this is a vacation, after all).
