This trail passes through five tunnels next to Lake Mead built for the rail line used during the construction of the Hoover Dam (the rails have been removed). The trail 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 are 4 miles if stopping at the fifth tunnel or 7 miles if going to the Dam. Add another 2 miles if you are going up to the bridge.

An abundance of desert flowers in the early spring, February and March. Plants include indigo bush, ground cherry, Mormon tea, cheese bush, rush-milkweed, rabbit brush, desert fir, globe mallow, desert tobacco, desert trumpet, rock nettle, rock daisy, and windmills. There are bats in the tunnels and sometimes big horn sheep climbing the steep terrain.
