I have hiked Bull Creek probably a thousand times and have explored every inch off trail.  When the park is empty is absolutely wonderfull.  I try to make sure I go some time other than summer.

The dog and I love this hike.  water is always flowing and after you get out of the main park area we almost never see anyone, except a horse or two on the trail.  Be sure and park in the actual parking lot to help protect your car from break-ins.  We cross over the raod hike up the other side and hike into Balcones reserve when it is open.  absolutely love the high trail that looks over everything.

I have done different sections at different times.  It is rough in spots, about first 2 miles in from TH you will run into hikers, walkers, runners in the early morning, but not many others after that.  The rocky parts at the beggining will kill you and your dogs feet.

After mile 2 there is about a mile of prairie opening that will bake your skin and brain-  I call it the death mile in the summer, but then you come the springs- even in the drought there is enough cold water trickle down the ferns to make life enjoyable again.
