As with most hikes in the Franklins, the trail is barren and exposed yet lined with a stunning selection of desert plants, including the stunning sotol cactus, nicknamed the "desert spoon." When removed from the cactus, the leaves form the shape of a spoon and have been essential tools for civilizations across centuries. The trail's rocky exposure also creates the perfect habitat for other desert wildlife, including the massive - yet intimidating - tarantula.

The trail begins with a gradual climb following a sandy wash, but it doesn't take long before it leads uphill via a series of switchbacks. The lower portion could be considered family-friendly, while the upper section is significantly more rugged and may be challenging for lesser-experienced or younger hikers.

Older and outdated maps often label this as the "Mammoth Rock Trail," "Mammoths Trunk Trail," or "The Window," though it is now officially listed as the Ron Coleman Trail per the park. There are no facilities at the trailhead along the highway, though the parking area is large enough to accommodate trucks and trailers with ease.

If you haven't visited the main visitor center slightly down the western side of Transmountain Drive, then you will need to bring $5 along for the self-pay kiosk at the parking lot. Those holding a Texas State Parks Pass, which comes highly recommended due to its value, will not need to pay.
