👍👍 We had a great time here! We opted for the guided "behind the scenes" tour and we were so glad we did. We had a shuttle ride to the top of the gorge with a fantastic view of the lake. That's where we started the tour with some great dinosaur fossil prints. From there, we had a great hike down to the...

👍👍 Nice old growth nature trails. The trails are maintained but the vegetation and trees are natural. Many big old trees. Some of the trails run along Olmos Creek. Most of the trails are dirt trails and may get muddy after rains so wear appropriate hiking shoes. Very much enjoyed taking a walk here.
