Following Sonora's coast north of Guaymas along the Sea of Cortez, the bountiful recreational area of San Carlos appears guarded by the Tetakawi, a jagged coastal mountain separating one of Mexico's - if not the world's - best natural harbors for small to medium sea-crafts.
North of the harbor and around a series of beaches nestled between the various coastal mountains that form the coastline, Playa Algodones provides a playful beach area and serves as a base for the area's Club Med.
Scuba divers find the caves along the coast and coral formations on nearby sunken ships interesting. Fishermen catch dorado, barracuda, and all the bill-fish including marlin, sailfish and swordfish in nearby waters. Hotels range from inexpensive efficient posadas to deluxe properties offering all amenities.
Trailer parks - ocean-front and inland - are popular for those seeking extended stays.
