Buenos Aires Costa Rica Airport (BAI) is a regional airport located in southern Costa Rica, in the Puntarenas province. It primarily serves domestic flights, often from San José or other parts of the country, and is a convenient gateway for travelers heading to the Osa Peninsula, the Talamanca Mountains, or nearby indigenous communities.
Though small in size, the airport is efficient and offers the essentials: a waiting area, basic services, and easy access to ground transportation. It is especially valued by eco-tourists and adventure travelers for its proximity to lesser-known but spectacular natural attractions.
