I think you mean South side of Sugarloaf which faces SGW that is the side that Wildhorse Trail starts. If you did mean North side then that side faces Big Bear which there is trail 2E18 from Green Spot Group Camp.
Otherwise look at the trail report by MikeH just a few post ago, he goes into great details of the trail. You can camp at Wildhorse Camp or any good place 100ft from trail or water since this isn’t SGW. Also MikeH posted some pictures on Reddit which I love the Husky pic. It makes me wish I had one since all the kids have grown up and moved out.
