“Run through five tunnels with the end of the run at Hoover Dam Visitor Center, then the bridge.”— John Blackwell
The trail passes through five tunnels next to Lake Mead built for the rail line used during construction of Hoover Dam. A newly opened lower section continues downward and ends on the top floor of the parking garage at the Hoover Dam. Another trail junctions with this trail to take visitors to the walkway that crosses the Hoover Dam Bypass bridge.
The total out-and-back distances is four miles if stopping at the fifth tunnel or seven miles if going to Hoover Dam. You can add another two miles if you are going up to the bridge. Elevation change is negligible.
