We had reserved 2 carts, and another family had resered 1.There were only 2 carts available. We used the 2 carts and 1 cart would hardly run. We had to push it to get it started again. We had to cut our day short because we were worried about getting back to the port.I would not recommend using Nathan's Golf Cart Rental.
Javin's is a great way to see the island. We saw lava rocks, had a walk through the rain forest with many trees and plants described to us, and snorkeled at 2 beaches. Add to these activities a rnning dialogue of interesting facts about the island and it added up to the perfect day. I would highly recommend Javin's Island Tours.
