Tortuguero National Park
There is no better place in Costa Rica to observe sea turtles nesting, hatching, and scurrying to the ocean. The July–October nesting season for the green turtle is Tortuguero's most popular time to visit. Toss in the hawksbill, loggerhead, and leatherback—the three other species of sea turtle that nest here, although to a lesser extent—and you expand the season from February through October. Hatching takes place September to December. You can undertake night tours only with an authorized guide, who will be the only person in your party with a light, and that will be a light with a red covering. Photography, flash or otherwise, is strictly prohibited. The sight of a mother turtle furiously digging in the sand to bury her eggs is amazing, even from several yards away, and the spectacle of a wave of hatchlings scurrying out to sea is simply magnificent.
Outside of turtle nesting season, there is an abundance of wildlife to observe in this raw and mostly impenetrable landscape. Boat tours on the canals run alongside towering raffia palms, their iridescent golden-green fronds stretching out over stoic caimans in the water below. Sloths are balled into tree branches, mustering the energy to forage their next meal, while the humid air echos with the digitized birdsong of oropendulas and the wild screeching of great green macaws. Smaller and quieter watercraft like kayaks or canoes allow for navigating the dense vegetation of teawater lagoons and palm swamps, and overhead, frequent bursts of rain are shielded by the outstretched branches of towering ceiba trees.
