In Costa Rica, there are no street signs and rarely house numbers. Getting from here to there involves knowledge of the metric system; understanding a bit of Spanish; keen eyesight; perhaps a four leaf clover; or a prayer to St. Christopher (if that’s your thing).
Travel with several maps. Hand written directions help and GPS can help. If you have to stop and ask directions, people will be eager to offer their opinion. Unfortunately the directions are sometimes wrong; a bit off; or impossible to understand. I’ve found, especially in the campo, Ticos thoroughly enjoy giving this information and love to help. The problem can be, after 500 meters, your’re lost again. Best bet is to ask again. Poco a poco, you’ll get there.
