In the past year I have visited Costa Rica for about a month and have driven over 3,000 kms. I’m interested in the country so I have driven north to Tamarindo and as far south as Palmar Sur. I simply wouldn’t do it without these maps. They are dirt cheap compared to getting lost or trying to reconcile your location with a paper map. It’s very difficult when you get off into the mountains and there are roads going in all different directions. You are going to Costa Rica. Spend the money (peanuts really) and know where you are!
