Bahia Concepcion, at 22 miles long, is the largest bay on the Sea of Cortez. The bay has several small islands lining the area. The Concepcion tends to be windy, particularly in the winter months, so there are always quite a number of boats anchored here. Even in the summer months the beaches tend to be crowded with RV's. There is no place to purchase supplies (or even ice) in Coyote Bay. You can rent kayaks here, or maybe take a tour of the area, or an educational program for children. There are many great places for snorkeling or diving, and because the bay is so shallow and well protected, the kayaking is also terrific.
