Cave Gulch Road is a narrow, steep point to point connector shelf road accessible May into December. If you have an oversized vehicle, proceed with caution. It is also part of Montana's Historic Garnet Mining Region. Rocky with small washouts in places, watch for sharp switchbacks and limited turnouts. Camping is allowed but challenging along this trail due to the shelf road. There is one nice camp spot with tremendous views in a large turn out with several existing fire rings.
Ultimately this trail ends in Garnet, Montana's best preserved Ghost Town also on the National Register of Historic Places. It is maintained by the Bureau of Land Management so there will be a small fee to explore if you choose to do so.
