The Savannah region is a boater's paradise with 420 miles of navigable waters dissecting 87,000 acres of tidal marshlands. Within a 50-mile radius there are 20 marinas with scores of companies offering kayaking, deep-sea charter fishing and dolphin tours, bird watching, and boat rentals. And, if your budget is looser, take your sailboat out to Wassaw Sound, where the 1996 Summer Olympic Games held their yachting events.
