The highlighted green area is Sonora state.

The large, prosperous state of Sonora is located in the northeast of the country. It is bounded by Chihuahua and Sinaloa and in the far northeast, it joins Baja California. It borders on Arizona to the north and is washed by the Gulf of California in the west. Its unusual landscape ranges from beaches to valleys and from plains to mountains and deserts, with the Sierra Madre Occidental stretching right across it.

It is inhabited by Yaquis, Mayos, Primas, Pápagos, Opatos, Seris and Guarijíos that still preserve the customs and traditions of their ancestors. Spanish presence is limited to the remains of Jesuit missions and towns that sprang up around the mines.

Sonora provides attractions for every taste: cave paintings, spectacular natural scenery, ideal for adventure and ecotourism, regulated hunting parks; an extensive shoreline with beautiful beaches and bays ideal for water sports and sport fishing. Another of its attractions is its superb cuisine, which combines seafood with the fruits of the land.
