Early morning or late afternoon is the best chance to spot wildlife in Tortuguero, and you will set out with the rest of your group for a gentle boat trip along a section of canal. Your expert naturalist guide will scan the tree tops and water’s edge, pointing out glossy cormorants drying their feathers, sleeping bats camouflaged on tree trunks and perhaps the dart of a bright green lizard scuttling along a drooping branch.
