Knowing the best time to visit Jaco generally means knowing the climate of the land. Fortunately, this coastal town is a decent vacation destination in Costa Rica any time of the year. Jaco is just 80 miles away from the capital city of San Jose, and the drive that takes tourists all the way there is definitely a pleasant two-hour view of the countryside. Getting around Jaco on foot is possible during daytime, and this town is fairly safe knowing the relative standards of Central America.
