More ways to explore the area's outdoor wonders
You begin on high desert ridgelines where the air tastes dry and the Mojave sun presses flat against your hat; the trail opens with a sweep of Lake Mead to the east and the concrete curve of Hoover Dam waiting downstream. The Historic Railroad Tunnel Trail follows the old engineers’ route—cut, blasted and graded to deliver supplies to the dam site—so every switchback feels like a step back into the construction era.
