Travelling around Grenada in a car would not be a very good idea. Too many beautiful places will remain outside your reach. You can hire a buggy or better still walk on foot. Grenada is only a small island and it does not take too much time to get from one end to the other. When you walk around the place, you can appreciate all the beauties of its astonishing nature especially if you join an excursion or hire a personal guide.
