Reached only by boat or small plane, Tortuguero is a maze of jungle canals and lagoons on the northern Caribbean coast — glide past caimans, river otters, monkeys and hundreds of bird species. Its beaches are among the Caribbean’s most important green sea turtle nesting sites, protected within Tortuguero National Park (nesting season roughly July–October). A car-free, water-borne world unlike anywhere else in the country.
