Check out Tieton Basin, Jumpoff meadows, good camping up at lost lake and you can actually drop off into the country behind it, the elk in that area are thick...There are ORV trails all over that the elk use just as much as the ORV's they make for quiet walking and good access also.
Roads to check out are 554, 557, and Lost Lake Road. The Lost lake is good trout fishing also from shore or canoe.
