Rhode Island State Parks and Recreation
These Rhode Island State Parks have handicapped-assisted surf chairs for visitor use: Roger Wheeler, East Matunuck, Salty Brine, Lincoln Woods, Goddard Memorial, and Scarborough. Colt and East Bay Bike Path have recreational hand-cycles. See Accessibility for more information. There are hiking trails in Rhode Island State Parks, but information about them is scanty. Let me know if you have a favorite.
