This little trail is just a few hundred feet long, but you can explore a small patch of Chihuahuan Desert, with some possible shade provided by the cliffs of Walnut Canyon. Interpretive signs identify plant life found along the trail and throughout the park.

An easy, paved trail less than half a mile round trip leads to a vista point overlooking Walnut Canyon. Not much of a hike, but a decent view.

Here's where you'll pay for your entrance to the park, as well as purchase any additional tours you might want to do. You can also explore the exhibits, get a bite to eat in the cafeteria (open 8am-4pm), and do your souvenir shopping in the gift shop. Lastly, this is also where you access the cave, either using the elevator or the back door for the trail to the natural entrance.
