As jungle paradises go, Costa Rica is as accessible as they come. Being in the Central Time Zone, flying times from many major U.S. cities to Costa Rica range from three to five hours. Guanacaste’s newly expanded international airport near the town of Liberia is a scenic one-and-a-half hour drive from the Lake Arenal region. Fly direct from Houston, Atlanta, Miami and other cities. Come by private jet. Or arrive via San Jose International Airport and board a 40-minute hopper flight to Liberia.
