went with the dogs, it's a bit of an ankle breaker at times, especially with a puller and there's a few places where you need to almost climb up rocks. we went after it rained so part of the trail was flooded and or slippery. but the views are great ands it's a solid hike. decent distance, although the section that's on the road is weird, watch out for cars.
There are a lot more trails here that aren't mapped. The best ones are a bit secret. Cross over the creek at the waterfall and head to the left and up. Then Traverse across the bluff (great view!) and there's a network of trails to explore.
A little less maintained than the Barton Creek greenbelt, but it's also less trafficked which is great. Plenty of quiet once you get away from the watering holes. The waterfalls here are an overlooked natural wonder in Austin. They are spectacular after getting some rain.
