ADIO Ostional Guides (Asociación de Desarrollo Integral de Ostional)

The Ostional Integral Development Association is one of two official community guide groups authorized to lead visitors into the Ostional National Wildlife Refuge, where entry without a licensed guide is prohibited by law. Guides walk small groups onto Playa Ostional to see nesting olive ridley turtles or, during an arribada, the mass nesting event that draws hundreds of thousands of turtles ashore between July and December. Reservations go through the association's own phone lines rather than a website.
