It's possible to travel overland to Costa Rica from the USA, crossing Mexico, Guatemala, Honduras and Nicaragua. The nearest US town is Brownsville, Texas, 4000km (2480mi) away. Overlanders can either catch a series of public buses or drive their own car. The main border crossing between Costa Rica and Nicaragua is at PeÃ±as Blancas on the western coast. There are three border crossings between Costa Rica and Panama for travelers heading to or arriving from the south: Paso Canoas on the western coast; Sixaola/Guabito on the Caribbean coast; and the little-used RÃo Sereno near the Parque Nacional VolcÃ¡n BarÃº.
International flights arrive at San JosÃ©'s Juan Santamaria international airport, though the airport in Liberia, 217km (135mi) northwest of San JosÃ©, has been upgraded and now operates as a second-string international airport. There are good connections to US and Canadian cities and several Latin and South American countries. Scores of tour operators in North America and Europe run tours to Costa Rica, though these tend to be for first-class visitors and expensive. There is a departure tax of around US$17 on international flights.
