单选题Vacationing in Mexico 在墨西哥度假 Each year more travelers are finding their way to the sun coasts of Mexico; where ancient civilizations once honored the sun, modern sun worshippers are discovering superb vacation destinations. Airlines now schedule weekly flights from major national and international points to a variety of sun coast resort areas. The peninsula of Baja California provides one of the most splendid vacation sites in the Western Hemisphere. The peninsula is divided into two states: Baja California Norte and Baja California Sur, which are now connected by the Benito Ju rez Trans-peninsular Highway, so that the entire peninsula can be easily reached by car, as well as by sea and air. A chain of new hotels offer deluxe accommodations, but there are also numerous camping grounds, trailer parks and wayside inns for those who prefer casual-living vacations. At the southern end of the peninsula, La Pazi San Jos del Cabo and Cabo San Lucas offer rapidly expanding deluxe facilities to accommodate the growing influx of visitors. All have good accommodations, restaurants, sports facilities and meeting rooms. In addition, La Paz, with its duty-free zone, is a shopper's paradise.

South along the coast are Topolobampo and Los Mochis, the former a ferry terminus serving La Paz on the peninsula, and boasting the largest natural bay in the world; and the latter a starting point for the Chihuahua-Pacific Railway trip which goes through the breath-taking Copper Canyon to the city of Chihuahua． Mazatlan, the sailfish capital of the world, has developed a large new resort complex to accommodate its many visitors.

An international fishing tournament is held there each fall. Modem convention and sports facilities are available.
