Red Mountain Trail near St George Utah

There is a nice trailhead off highway 18 to the north of St George and one of the maps did show a complete route North south ending at the small city of Ivins. I would want to see if possible by day tripping the southern side since the topography on Gaia doesn't make the route feasible but I ran into a group of 3 older folks who said they have heard of it being done before. GPS Red Mountain Trailhead Desert snakes freak me out every time The top of the rim where the trail continues south to Ivins Peering through the wilderness area and West Canyon Road Wilderness area boundary
