Lindblad Expeditions' co-branding partnership with the National Geographic Society turns a Galapagos voyage on Endeavour into a floating university, with naturalists and a magazine photographer on board every sailing. This former work vessel holds 96 passengers in 56 cabins, all of which have either windows or portholes. A lot of thought went into designing the ship to reflect the purpose of the trips, which means locally grown food, handmade textiles, and a glass-bottom floating spa. The real privilege is the up-close and expert view of the show-stopping fauna.
