After turning off the main road, a half-mile drive takes you to a petrified tree located on a hillside. No RV’s or trailers are allowed. A short walk up an incline boardwalk followed by a dirt path puts you at the base of the petrified tree, surrounded by a protective metal fence. At the furthest end of the parking lot a sign indicates the Lost Lake Trail. See Lost Creek Falls and Lost Lake Trailhead under Roosevelt Lodge.
The Petrified Tree was mentioned in our article titled: "Best Places to Go and Things to do with Kids in Each of Yellowstone's 14 Road Sections"
