Float down Costa Rica's bayou looking for monkeys, sloths and toucans among the rainforest foliage of Tortuguero National Park. Slip into a canoe or a kayak for a stealthy wildlife adventure or wait until nightfall and join a nighttime canal tour looking for bats, birds, tapirs and elusive kinkajous. Bird watchers will relish waking up early for the more than 375 bird species that frequent Tortuguero including egrets, herons, anhingas, jacanas, king fishers, trogons and endangered species like the green macaw.
Visit from July 1 through September 30 and you'll have the chance to see green sea turtles on Tortuguero Beach during nighttime nesting tours. Stroll along the beach in the early morning and late afternoon and keep your eyes peeled for baby turtles emerging from their nests and scampering toward the sea. Other than wildlife watching, you can ride zip lines through the rainforest on the Senderos Aereos canopy tour.
