Nice trail system. Parts of the trails have been re-worked. The trail now routes through the woods rather than down the pipeline which is nice. New bridges have been built over sections of the dry creek drops making it easier to get through. Additional trails have been added as part of the transition of the trails into hike and "bike" trails. Mountain bikes are now welcomed. Be mindful of falling limbs and trees since the area has a lot of dead trees from pine beetles and the drought.
We completed the full 7.7 miles. This hike does not provide any scenic views but does provide tranquility. Be aware - there is a lot of tree stumps from new reworking of the trails and also tree roots throughout.
This hike was a nice leisure hike for the hot Texas summer. The trees provided a nice canopy.
Another note: the trail is not 12 miles. As stated by the designated trailhead signage, the trail is 7.7 miles round trip. Well established, easy trail with a few small hills. Due to the drought, the park rangers appear to be taking an active role in removing hazards of dead falling or felled trees. There is a green belt at about .3 miles in that serves as a natural gas pipeline route. Great place for a jog.
Fairly scenic, would be better in spring/fall. When I went it was 100+ degrees and dry so the vegetation was mostly dried out (there has been a serious drought in Texas). Not a difficult hike as far as elevation change. I thought it was easy to moderate at best. Trails are well defined.
