National Geographic Sea Lion

The National Geographic Sea Lion is perfectly sized to explore remote, wild places in the Sea of Cortes inaccessible to large ships.

National Geographic Sea Lion, like her twin ship National Geographic Sea Bird, is a tried and true expedition ship that plies the waters of Baja California and the Sea of Cortez. With a shallow draft and small size, she can easily reach places inaccessible to larger ships. She can venture into fast-moving channels where whales come to feed, transit an series of lockes in the Pacific Northwest, nose up to waterfalls in secluded coves, and sail into protected anchorages in small bays perfect for snorkeling and kayaking.

Sea Lion accommodates 62 guests in 31 outside cabins. Her inviting public spaces foster a sense of shipboard life where everyone is integral to the adventure, engendering a sense of expedition community.  All accommodations are outside facing with one or two windows, and the cabins on the upper and bridge decks open to the outside deck. Double-occupancy cabins include two single beds, and some category three cabins feature two lower single beds that can be converted to a double bed, plus a pullout single bed for a third person.

She is equipped with tools for exploration that guarantee us an in-depth experience in all the places we explore, and her open bow is a natural gathering place that accommodates the entire community at once for shared wildlife viewing experiences. Our expedition style is active, casual, and engaged. There is no need for formal clothing, and the services offered aboard ensure travel is effortless.
