Bike the Historic Railroad Tunnel Trail

In 1931, the federal government partnered with Six Companies, Inc., a group of six major western construction firms, to build nearly 30 miles of railroad connecting the Hoover Dam and Boulder City. The route was essential in the dam's construction as it allowed workers to move materials and resources from nearby cement mixing and gravel sorting plants and the quarry pits to build the dam. The railroad tracks were dismantled in 1962. The current multi-use trail was established in 1992 and connection to the Hoover Dam in 2007. Today the trail, perfect for hikers, features incredible vistas of Lake Mead and Boulder Basin and five tunnels – each approximately 25 feet wide.
