Central Florida - Monroe Harbour Marina on Lake Monroe is part of the St. Johns River. Ashore, Historic Downtown Sanford with its shops and historic buildings are a few blocks away. Sanford's RiverWalk, meanders along the lakeshore on both sides of the marina. Developers are also continuing with the construction of magnificent waterfront town homes and condominiums and brightly painted riverfront shops and restaurants. Our central location also means easy access to the Orlando area's world famous attractions, as well to Daytona and the beaches.
