El Paso sits on the Rio Grande at the western tip of Texas, facing Ciudad Juarez across the river and backed by the Franklin Mountains. Franklin Mountains State Park offers desert trails and views over the city and the desert, the El Paso Mission Trail links historic missions in Socorro and San Elizario, and the El Paso Museum of Art shows European, Mexican, and American work downtown. The Plaza Theatre presents performances in a restored 1930s movie palace, and the Chihuahuan Desert Gardens at the University of Texas at El Paso display desert plants.
