The municipality, especially San Carlos, is popular with visitors from Arizona and Sonora, but much of the coastal area, where the stark desert landscape meets the calm waters of the Gulf of California, is still undeveloped. San Carlos is an important destination for sportfishing with modern piers and 800 species that can be caught including sailfish, marlin, yellowtail and others. This bay holds a fishing tournament each year in July called the Torneo de Pesca de San Carlos. San Carlos also has an aquarium dedicated to dolphins and sea lions, which perform shows. The most notable peak in San Carlos is called the Tetacawi or Teta de Cabra, which appears to have two horns. Teta de Cabra means “goat’s udder” which it is supposed to resemble. Other sports that can be practiced here include kayaking, sailing, jetskiing, snorkeling, scuba diving, mountain biking and hiking. San Pedro Island off the coast is popular for snorkeling, scubadiving and visiting the sea lions that live there.
