Ferry Service from Playa del Carmen arrives several times daily. There are no public buses on the island so your choices for transport are walking, cabs, car, scooter, and bike rental. Cabs are abundant and although they are pricier than on the mainland they are still a good deal. Scooters and bikes can be rented for about $10-$25 dollars a day. Cars/jeeps are closer to $80 for the day. Much of the island is paved especially in the more tourist laden areas however a lot of your side street adventures will get you off the pavement onto dirt roads so rent your vehicles accordingly.
