Thousands Islands, New York There are more than a thousand reasons for visiting New York’s Thousand Island- as a matter of fact, 1834 islands and reasons. Located off the northwest shore of Lake Ontario(安大略湖) and up the St. Lawrence Seaway (圣劳伦斯海道)， these attractive islands offer tourists not only the clear blue sky and water, but also romance, family adventures and various activities. A century ago, the Thousand Islands attracted rich and famous visitors with expensive hotels and great stone houses. Today, the Thousand Islands have become an affordable vacation wonderland. You have the choices of staying at a modern hotel, a houseboat, a bed-and- breakfast inn, or even on your own personal island All the Thousand Islands can be reached by a houseboat, however, many are privately owned. Take a boat, slipping into quiet coves(河湾)to fish and swim, or cook the day's catch. Visit friends on their rented islands (reached only by boat). Sail to Alexandria Bay for a quiet dinner at one of the many fine restaurants. Or simply relax on the deck, enjoying the clear air and peace. The boats vary in length and size, but all come equipped with kitchen, bathroom with shower, two roomy decks, bedroom, bunk beds (双层床) and living room. With so much space, houseboats are a great travel idea for families with children or groups of friends. Once you boat into this area, you enter a world of timeless beauty and peace. Housekeeping cottages along the St Lawrence River have rapidly become the most popular accommodations ( 住宿) for a Thousand Island's vacation. These and island cottages are generally rented on a weekly or seasonal basis. Most cottages will supply rental boats to transport you from the mainland to your vocation home, as well as to island parties during your visit. The most famous landmark of the area is Heart Island, so named for its shape. Boldt Castle was built there by George C. Boldt as a monument of love to his wife, Louise.Tragically, Louise died before the castle was finished. The castle rises six stories above the island, in the middle of the river, and is the central point for all visitors. It is open daily from mid-May through mid-October What is the purpose of the writer?
