Windswept beaches, sand dunes, blinking lighthouses and a charming pace of life await on this 50-square-mile island. The world's former top whaling port is now designated a National Historic District. Leave the car and take the shuttle, or bike around. Seaside cottages, old whaling captains' mansions and historic harbours contain quaint inns, tiny shops, chowder shacks and upmarket dining delights. Swim, surf or load up the tackle for Nantucket's excellent striper, bluefish and bonito fishing.
