This is a lovely county park. It is more of a veloway than a hiking trail, but the birdwatching was worthwhile. Also, there are multiple nice playgrounds and a ton of grilling areas, including some more quiet picnic tables. The old Congress Avenue Bridge was interesting.
Uneventful sidewalk around a park full of grills and picnic tables, and no less than 6 bounce houses in use this March Sunday Afternoon. However there is a 3-span Truss bridge from the 1800s that was moved from the Congress Avenue crossing of the Colorado River that was moved here (Moore Crossing) and the traffic has been rerouted but you can still walk across this bridge, and is a Texas Historic Site.
