Parismina, a small village in Costa Rica between the Reventazón River and the Caribbean Sea, is only accessible by boat or plane. Three species of turtle – leatherback, hawksbill and green – lay their eggs on the beach there. Marine turtle populations are in decline worldwide and Parismina doesn’t buck the trend. In 2001 a group of teenagers, alarmed by the rise in poaching, joined forces with the coast guard to patrol the beach and went on to found the Asociación Salvemos las Tortugas de Parismina, a non-profit conservation project.
