We paid $50 per person for the four-wheeler trip that took about four hours. I rode with my husband, but it would have cost the same to drive one myself. We rode through sugar cane fields and stopped for a taste of the sugar cane.
The guides took cold water and Coke for the trip. We also stopped for fresh fruit and more water/Coke to drink, which is included, and there was a bar which served liquor for those who knew to take extra money (we didn't). We probably wouldn't have had any money left because we would have given to all the children who were begging for dollars. It was a fun excursion.
