This trail offers stunning views of the canyons and takes you past ancient Puebloan ruins on the way to the summit. The hike starts off relatively easy, but the final miles are the most challenging. There are numerous side trails branching off the main path, perfect for exploring the area further. This particular route extends beyond the official trail markings to San Canyon Pueblo, but feel free to turn back before reaching the pueblo. ( Sand Canyon Trail on AllTrails)
