Costa Rica's Surfing Paradise

Season 17 Episode 1701

On Costa Rica’s Pacific coast, the surf break at Playa Hermosa is a world-class wave—and the heart of a vibrant ecosystem where endangered sea turtles nest. Recently named a World Surfing Reserve, it’s now the focus of a bold conservation effort, as community members work to restore forests, protect wildlife, and preserve the powerful waves that shape their way of life.
