My husband and I have spent several years hiking around south and central Texas (as well as New Mexico, Colorado, west Texas, etc). While I would not rate Inks Lake with some of the bigger National Parks that we've hiked, it is one of the best state park hikes we've had in the area. Even on a crowded spring Saturday, the farther trails were pretty much empty, and most of those we saw on the trails were there with dogs and good attitudes. The trail markers were easy to identify. I would take a few highlighters and mark up your map to the color-coded map posted at the trail-head, as these colors will correspond to the trail markers.
For a post-hike cool down, be sure to check out the Devil's Watering Hole.
Overall, I was surprised by how impressed I was with Inks Lake State Park.
