Wild and inhospitable, the Bisti/De-Na-Zin Wilderness is a rolling landscape of badlands that can’t be fully accessed by road. They're ideal for hardcore hikers looking to escape the crowds. Once a river delta, this area has topography like you’ve never seen. When the water receded from these parts, it left behind bizarre rock formations made of sandstone, shale, mudstone, coal and silt. There are pinnacles, spires and mushroom-shaped rocks, caused by weathering over the millennia. With little shade, no water sources and searing summer temperatures, a day out here is for the hardy.
