River Mountains Loop

Completed in 2012, this 34-mile paved trail forms a loop around the River Mountains and connects Henderson, Boulder City and the Lake Mead National Recreation Area. Popular with hikers, runners and cyclists, the trail offers plenty of opportunities for interesting detours (try the five tunnels of the Historic Railroad Trail), scenic outlooks, wildlife encounters (think bighorn sheep and desert tortoises) and welcome breaks (a pint at Boulder Dam Brewing Co.). Take it on as a full loop or sample individual sections for more manageable mileage.
