Day 4:   Golfo Dulce, Costa Rica
Enter the mangrove-fringed Golfo Dulce along the southwestern edge of Costa Rica as our nimble expedition ship takes us into the remote upper reaches of this placid bay. Exploring by Zodiac, paddleboard and kayak, we encounter Pacific Costa Rica’s dazzling avifauna as we watch for golden-hooded and Cherrie’s tanagers, yellow throated toucans, fiery-billed aracaris and crimson fronted and orange-chinned parakeets, constantly chattering in flight above the jungle treeline. The flora is a kaleidoscope of tropical color with bromeliads, heliconias and orchids set against the verdant green of the tropical forest. Later, jump into the cool, refreshing waters of the bay for an afternoon swim. All meals included on this day.

Day 5:   Coiba National Park, Panama
The first stop in Panama this morning is at the remote Isla Coiba, one of the many islands of Coiba National Park, a UNESCO World Heritage site. Once a penal colony, the island has long been protected and accessible by special permit only. Among its many endemic species are the Coiba Island agouti and the mantled howler monkey, as well as four varieties of sea turtle. Discover rich marine life while snorkeling, go kayaking or hiking, try stand-up paddleboarding, or simply relax on the beach. All meals included on this day.

Day 6:   Gulf of Panama Islets / Panama Canal Transit Today, explore
the tiny islets of the Gulf of Panama by Zodiac or kayak. Here we might spot frigatebirds, brown pelicans, neotropical cormorants, and brown boobies. Set sail for the Panama Canal this afternoon. Stretching more than 50 miles, the canal was a colossal engineering feat completed in 1914. It is still traversed by some 14,000 ships every year.  As cargo ships tend to pass through the canal during the day, we’ll most likely begin our crossing at night, when the canal is dramatically lit. All meals included on this day.
