Grandview Trail starts at the overlook and drops toward Horseshoe Mesa. It is steep, rocky, exposed and strenuous: a route for experienced desert hikers, not a casual extension of the viewpoint or a recommended first hike below the rim. There is no maintained water on the trail, and springs are seasonal and unreliable. Summer heat and monsoon lightning, plus winter and early-spring ice, make preparation important. Below-rim camping requires a backcountry permit, with designated sites on Horseshoe Mesa.
