The newest opening of Phase III brings the trail to an impressive length of 6.75 miles and has extensive landscaping and scenic views.  The trail meanders along Brushy Creek from just east of Great Oaks Drive west to US 183 in Cedar Park and offers a relaxing atmosphere with the convenience of being minutes away from many bustling communities. 

The grand opening was on March 7th, 2009, celebrated with a 5K TrailSetter Race hosted by the Greater Williamson County YMCA and then a children's 1K. A ceremony was held after the race, with Commissioners Long and Birkman, and Congressman Carter speaking. 

The trail has six parks which lie along it: Creekside Park near Great Oaks Drive, Olsen Meadows Park, Champion Park, Brushy Creek Lake Park, Brushy Creek Sports Park, and Twin Lakes Park near 183 in Cedar Park. These parks provide many different amenities accessible to walkers, runners and bikers. Together, the parks have a collaboration of splash pads, swimming areas, climbing rocks, fishing docks, canoeing and kayaking, restrooms and multiple picnic and pavilion areas. The trail links residential communities, businesses and retail centers and existing and proposed parks while promoting conservation and stewardship of open space, greenbelts and wetlands. To get directions, please go to view map.
