The U.S. Forest Service is reminding the public of closures on Cathedral Rock Trail in Sedona beginning Wednesday. The upper portion of Cathedral Rock will be closed to the public so crews can reconstruct rock walls and check steps. The lower portion of Cathedral Rock Trail will still remain open during construction. The U.S. Forest Service reminds hikers to stay clear from the area and watch for falling rocks due to the steep terrain. The construction is aimed to be completed by April 30th.
