A brand new highway known as Autopista Del Sol (Highway of the Sun) that stretches from the beaches around Orotina all the way into San Jose. Unfortunately, parts of it are sometimes closed for repairs.
Due to the unpredictability of road conditions and lack of safety features, driving at night is highly inadvisable. If you see a tree branch or pole poking out of the middle of a road, that is a "sign" that there is a deep sinkhole, pothole or manhole without a cover. Stay away from it.
Another easy way to get around Costa Rica is to use the services of mini-vans at most of the hotels. The vans are clean and comfortable, and they take you from door to door.
