Chihuahua is a Mexican federal state. It borders the state of Sonora to the west, the state of Sinaloa to the southwest, the state of Durango to the south, the state of Coahuila in the south, the U.S. state of Texas to the northeast and the U.S. state of New Mexico to the north. Its capital is the city of Chihuahua.
Most sources of information don't recommend travelling in Chihuahua due to safety issues and the Mexican drug war. However, Chihuahua is the biggest state of Mexico and you will be fine in most parts of it, especially in rural areas and villages, away from big cities and highways. Be careful in the city of Chihuahua though and extremely careful in the border city of Ciudad Juárez. Ciudad Juárez is the most dangerous city of Mexico.
