This was my first hike in West Texas and it exceeded my expectations. This state park has about 6 miles of trails plus a short nature trail near the park HQ.
The hike is a little plain, but the trails are wide and extremely well maintained. At the end of the hike, you are given a spectacular view of Panther Cave and the Rio Grande river as it pours into Seminole Canyon. You get cliff vistas several hundred of feet over beautiful green water. It is quite astounding and makes the hike worthwhile. You can also walk around off the trails to get a better view of the river.
There is also a small guided tour trail that takes you to the Fate Bell Rockshelter Weds - Sun. Unfortunately, I was there on a Tuesday, so I was not able to take this guided tour, but I was able to get to a point where I could photograph the rockshelter.
One other thing that makes this hike interesting is to find the fossilized imprints of sea creatures in the limestone that date back approximately 100 million years. It is like walking through an outdoor museum of natural history.
I highly recommend hiking this park!
