We will be flying in to San Jose and renting a car for a week. Plan is to drive to La Forunta, spend an adventurous 3 days, then drive to Tambor/Cabano/Malpais to vegetate on the beach. On day 7 drive back to San Jose, day 8 fly home. This seems like a lot of driving, but budget-wise better than flying. The big question is, do we need a 4x4 to do this? We will be travelling the first week of June.
