This is the newest MTB bike trail in Dallas, opened in Dec, 2010. As of 4/5/2011 there are two main loops (Blue, Green) and a yellow bypass section. There is a longer orange section under construction. (We are trying to have it open by Mid May 2011) Start with the Blue section in the front, it starts with easy single track a narrow tree gate and a bridge crossing with a coupe of crossings over some rock piles. At the split either take the yellow bypass to the left (easy route) or continue on the blue loop to the right. This part of the blue winds up and down along the bank of the creek and the railroad right of way, intermediate level for the 1st half of blue loop. You can get a really good workout if you push it. The blue meets back up with the yellow at the bridge for Walnut Hill road. Go left to stay on blue loop back the the parking lot, (this section is mostly flowy and fast), or go right under the bridge to the Green loop. The green loop climbs up and down the bank of Walnut Hill road and then along the bank of the DART line, lots of off camber. The 2nd half of the green loop is flat with some twisty parts and tree gates. The (under construction) orange section (when finished) will add about 1.7 more miles and we plan to add more trail inside the green loop. There is 4 miles now and should be about 7.5 miles of trail when finished. See the DORBA.ORG website for instructions on how to get from the paved "White Rock Creek" trail to the Harry Moss trail.
