Rock overhang over the trail was pretty awesome, but not that out of place if you have explored the rest of the park.
One caution, if you are afraid of spiders, don't look up! Your worst nightmare is hanging out above your head. There were about 12 million daddy-longlegs - give or take a few million - hanging out in colonies on the "roof" of the rock overhang.
The trail has some very pretty views of creek, a amazing bald cyprus tree (the largest in Travis County - says a sign). The trail itself is interpretive... but there were no guides at the start of the trail. "3" "7" and "13" don't have much meaning as you walk along the trail... but at least you realize that there is something special there.
Wildlife report: many many songfull birds (at least some cardinals, summer tangers, a probable oriole, many pigeons) and we got to experience another stare-down with a rabbit who was hanging out on the trail.
