Arrive in Panama City / Embark in Colon, PanamaUpon arrival in Panama City, transfer to Colon to embark your home for the next week. Set sail for the first part of your Panama Canal transit, anchoring in Gatun Lake for the night.
Barro Colorado / Panama Canal TransitIn the morning, board an expedition landing craft for Barro Colorado Nature Monument in Gatún Lake. This island has been the primary Smithsonian center for tropical rain forest study since 1923, and for this trip you have special permission to visit the facilities at the Smithsonian Tropical Research Institute. Meet some of the scientists and learn about their work before reboarding to continue your crossing. Often travelers have the opportunity to cross part of the Canal during the day, and another when it is dramatically lit at night.
Gulf of Panama IsletsThis archipelago of islands due south of Panama City has a storied past — pearls, conquistadors, buccaneers, and so much more. Explore the turquoise waters via expedition landing craft or kayak, where you might spot frigatebirds, brown pelicans or brown boobies. Observe roosting and nesting magnificent frigate birds and blue-footed boobies on an otherwise empty stretch of white sand.
Isla Coiba National ParkIsla Coiba is one of Panama’s most remote national parks, where you may hike the tropical, moist forest trails. The area is also perfect for swimming and snorkeling amid tropical fish. The ship's staff assists both novice and expert snorkelers alike. For those preferring a drier clime, naturalists take underwater footage, which animates your evening gathering in the lounge.
Golfo Dulce, Costa RicaToday make your first landfall in Costa Rica. At Casa Orquídeas, a privately owned garden accessible only by boat and special invitation, see a profusion of orchids, and look for tanagers, parrots and gaudy toucans. Later, explore the forested bay of Golfo Dulce, ideal for kayaking, expedition landing craft cruises or swimming.
Osa PeninsulaThe Sea Lion anchors off the remote Osa Peninsula and the environs of Corcovado National Park. Your exact landing spot for the day depends on sea conditions. You may swim in waterfall pools, horseback ride, or join a expedition landing craft cruise. Trek through the rain forest for a chance to see three species of monkey in one day: howler, spider and squirrel!
Manuel Antonio National ParkThe abundant wildlife here is most active in the early morning, so be sure to get an early start. Lethargic three-toed sloths can be easy to spot, but it often takes the expert eye of a naturalist to point out monkeys or vividly colored birds as they zip through the forest. In the afternoon, explore Costa Rica’s beautiful coast where you can find a great spot for a final hike or swim.
Disembark in Herradura / Transfer to San JoseDisembark your ship this morning in Herradura and drive to the airport for flights home, or on to other adventures.
