100 years ago Picacho was a gold mining town with 100 citizens. Today the site is a State Park, popular with boaters, hikers, anglers and campers. The park offers diverse scenery, including beavertail cactus, wild burros, bighorn sheep and thousands of migratory waterfowl. (The park is on one leg of the Pacific Flyway.) Eight miles of the lower Colorado River are the recreation area’s eastern border.
