The National Geographic Sea Lion* is designed to navigate narrow inlets and wildlife-rich passageways inaccessible to larger ships, while comfortably accommodating 62 guests in 31 outside cabins. Along with spacious viewing decks, these nimble vessels carry innovative exploration tools, including a SplashCam and a hydrophone that enable us to look and listen beneath the waves.

*Please note that for the duration of the 2023 season, guests 21 years of age and older will receive free beer and wine aboard all departures on the following expedition cruise ships: National Geographic Quest, National Geographic Venture, National Geographic Sea Bird, and National Geographic Sea Lion.
