Mexico has more than 120 golf courses, concentrated in the resort areas, with excellent options in Mexico City and Guadalajara. Los Cabos, in Baja Sur, has become the country's preeminent golf destination; the Puerto Vallarta area enjoys a growing reputation. Visitors to Mexico can also enjoy tennis, racquetball, squash, water-skiing, surfing, bicycling, and horseback riding. Scuba diving is excellent, not only off the Yucatán's Caribbean coast (especially Cozumel), but also on the Pacific coast at Puerto Vallarta and Manzanillo, and off Baja in the Sea of Cortez. Mountain and volcano climbing is a rugged sport that allows you to meet like-minded folks from around the world. The top peaks are just 80km (50 miles) south of Mexico City -- the snowcapped volcanoes Ixtaccihuatl (5,255m/17,342 ft.) and Popocatépetl (5,420m/17,887 ft.). Popocatépetl was not accepting visitors at press time, due to recent volcanic activity. For information on visiting and climbing the volcanoes, contact the Club de Exploraciones de México in Mexico City (tel. 555/740-8032).
