Twin expedition ships, M.V. Sea Bird and M.V. Sea Lion, can reach places inaccessible to larger ships due to their small size, yet each comfortably accommodates 62 guests in 31 outside cabins. The feeling, we’re told, is often compared to that of a large private yacht, with everyone integral to the adventure.

Sea Bird

Accessibility means freedom. The captains have decades of sailing experience in the regions we explore. They know when and where to navigate so that you feel the places we visit are all ours. Thanks to our sturdy fleet of Zodiacs and virtually untippable kayaks, you can be off the ship and out exploring within a moment’s notice. Launch your kayak from a picturesque beach, hike with our naturalists into the rain forest or walk easily along a sandy dune.

During your time aboard, the ship’s expedition staff likes nothing better than to surprise and delight you by directing the ship toward breaching whales, bow-riding dolphins or into an alluring cove. The seasoned crew consists of expert Zodiac drivers and considerate service providers. Their energy, enthusiasm and field expertise are sure to enhance your experience. This is what expedition travel is all about: not just seeing wildness, but being out there, in it.
