Some background: I'm 27 and have been mountain biking for about two months (so not crazy experienced). I live around McCallister Park, so that's been my primary trail system. Today was my first time along the green belt. Here are my thoughts:
There aren't any signs (or from what I saw, a designated trailhead). I just parked behind Blatman Elementary and started biking till I lucked upon some trail. As mentioned in another post, the City is expanding its concrete Green Belt System from Huebner to 1604 and beyond (eventually to Eisenhower Park), so a majority of the "trail" I rode between 1604 and Huebner was dirt being excavated for the future trail. It was pretty, but not fun to ride.
Once I went under the Huebner bridge, the trail became actual single track, but the trail had a ton of large rocks and it was tight. Either I lacked the technical skill to enjoy it or I'm spoiled by the flow of McCallister Park's Blue Loop, but I didn't enjoy the ride much. Once I reached the bridge at Blanco Rd, I took the paved Green Belt trail to Huebner and rode the excavated dirt back to Blatman.
So in sum, this was my first time on this trail, the trailhead (to my knowledge) isn't well defined, portions of trail are under construction, and I didn't enjoy it as much as I enjoy McCallister. I'll probably give it another try down the road and maybe my opinion will change.
