Most areas of Block Island are easily within walking distance of each other but there are plenty of other modes of transportation. If you prefer to travel by car you can flag down a taxi or rent one on the island. For a nominal charge, the visitor may bring a bicycle on ferries that serve the island. Bicycles and Mopeds are also available to rent and are so convenient that you may rent one as soon as you walk off the ferry. The "traditional" ferry from Point Judith, RI is the only ferry that takes cars. For rates and schedule,Interstate Navigation (http://www.blockislandferry.com)
