Despite its name, Davis Lake doesn't take you to a fantastic lake but many small ponds and wells that are used by cattle ranchers in the area. The draw for this trail is the extensive views of the Henry's Fork caldera system of the Yellowstone Volcano. The eruption that caused this relatively flat area happened around 1.3 million years ago. As you drive across the flats, you randomly encounter rocky patches where the lava rock pops through the dirt. This makes for a few small obstacles as well, requiring high clearance and possibly 4WD. Camping is sparse as long as you don't mind bovine company. You are better suited to finding camping closer to Highway 20.
