Road cycling
The Historic Railroad Trail Loop offers a moderate racebike experience covering 11.1 miles (17.9 km) with a total elevation gain of 1245 feet (379 metres). You can expect to complete this route in about 1 hour and 15 minutes, cycling through a unique desert landscape. As you pedal, you'll be treated to expansive panoramic views of Lake Mead and the Boulder Basin. The route follows an old railroad bed, leading you through five historic tunnels that add a distinctive character to your ride. Keep an eye out for the rugged rock formations and unique Mohave Desert vegetation along the way.
When planning your ride, be aware of the intense summer heat in the Nevada desert. Temperatures can make this trail unadvisable between June and September, and often from mid-April to late October. If you choose to ride during warmer seasons, plan your trip for cooler morning or evening hours. It is crucial to carry plenty of water, as shade is limited, especially for the first 1.5 miles of the route.
This trail offers a compelling blend of natural beauty and historical significance. The old railroad bed you follow once played a vital role in the construction of the Hoover Dam, with the tunnels serving as a testament to that era. Beyond the engineering marvels, you might spot desert bighorn sheep and other local wildlife. The unique Mohave Desert ecosystem provides a backdrop unlike any other, making this loop a notable choice for road cycling in the region.
