Costa Rica has two international airports. The main one, of course, is in San Jose, the capital. We use the one in the northwest near the small city of Liberia, situated to serve the gorgeous areas along the Pacific coast.
When flying in from Miami, the plane leaves the Caribbean at the north of Nicaragua, then turns south along the west side of Lake Nicaragua (the 19th largest in the world). The two cones of Ometepe Volcano are off the left wing so we always get seats on that side.
