The Sports Scene in Mexico

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.
