About 20 miles south of Sierra Vista is a 5,000-acre preserve dedicated to Francisco Vásquez de Coronado, the first European to explore this region. In 1540, Coronado, leading more than 700 people, left Compostela, Mexico, in search of the fabled Seven Cities of Cíbola, said to be rich in gold and jewels. Sometime between 1540 and 1542, Coronado led his band of weary men and women up the valley of the San Pedro River, which this monument overlooks. At the visitor center, you can learn about Coronado's fruitless quest for riches and check out the wildlife observation area. A quarter-mile from the visitor center, a trail leads three-quarters of a mile to 600-foot-long Coronado Cave. (You'll need to bring your own flashlight.) After stopping at the visitor center, drive up to 6,575-foot Montezuma Pass, which is in the center of the memorial and provides far-reaching views of Sonora, Mexico, to the south, the San Pedro River to the east, and several mountain ranges and valleys to the west. Along the .8-mile round-trip Coronado Peak Trail, you'll also have good views of the valley and can read quotations from the journals of Coronado's followers. There are also some longer trails where you'll see few other hikers.
