Colombia Lagoon is a large body of saltwater consuming most of the 247 acres of Punta Sur Park. The lake is dotted with islets and surrounded with vegetation. This reserve is a critical element in the park’s ecological mission to protect native flora and fauna. Climb the watchtower for an elevated view of all the wildlife including crocodiles. Bird watchers love catching glimpses of flamingos, herons and spoonbills plus several indigenous species. The best month for migratory birds is in May.
