This is a great trail for a person or family. The trail extends as far as the YMCA in Cedar Park and you can start there and take the path to the paved trail. It's a bit long for kids to take the trail to and from the YMCA but great exercise for walking, running and biking.
I love this trail due to the length. It stretches from Round Rock all the way towards Cedar Park. Usually walk the trail for about 3 hours once a week with my dog. Tons of scenic view and passes through multiple parks and rivers. Only downfall is that it is over populated on the weekends.
