Culture, customs and safety
Cultural heritage
The Osa Peninsula in southwestern Costa Rica is a region of extraordinary cultural and ecological significance. Long inhabited by indigenous groups such as the Boruca and Guaymí peoples, the area retains deep traditions in artisanal crafts, subsistence farming, and spiritual relationships with the land. Architecturally modest but culturally rich, its rural communities reflect a legacy of self-sufficiency and environmental stewardship. The peninsula is home to Corcovado National Park, part of the UNESCO-recognized Area de Conservación Osa, which safeguards one of the most biodiverse ecosystems on Earth. Today, the blending of ancestral knowledge with conservation efforts defines the region’s living heritage.
Safety notes
The main risks are environmental. Never hike alone off marked trails, swimming at remote beaches can involve dangerous riptides, and always use certified guides.
