The Grand Circle is a classic flowy loop with beautiful views in the Red Rock Canyon National Conservation Area, just outside of Las Vegas. The loop starts at the trail junction next to the weather station just next to the visitor's center. The loop starts out with a big climb, paralleling the gorgeous Calico Hills. The rolling climb continues up to the White Rock Trailhead, where it turns downhill, heading back to the start at the visitor's center, in direct view of the gorgeous sandstone bluffs.
