I will be in St. Barths on a cruise ship stop on Jan 11, 2012. I will be there from approx 9am to 6pm. I am thinking of renting an ATV from St. Barth Adventure for the day. Does anybody have any reasons why I should NOT do this? Would a car rental be cheaper/easier? I do not have experience with ATVs, but I do have experience with motorcycles. Any suggestions on lesser known places that I should try to visit?
