The Wild Wombat Loop is a 19k circuit that meanders up and down the Lergerderg Gorge in the Lerderderg State Park, Victoria. With some steep climbing and descending it takes in over 1000m of vert in less than 20km. The terrain consists of rocky single track, 4WD and fire roads, as well as some minor scrambling and a couple of river crossings. Due to the steep nature of the gorge it is not recommended to try the route after heavy rain as water levels can rise rapidly. 

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.
