There are 4 trails in Cedar Hill State Park. The largest (Dobra) is a shared use mountain biking and hiking trail. The remaining trails (Overlook, Duck Pond, and Talala) are only for hiking. The trails are closed if they are wet, to prevent the paths from erosion, and closures are common during times of the year when it rains often. Fortunately, you can check on the status of the trails before you visit the park by calling 972-291-3900. You are allowed to have your dog out on the trails, provided they are kept on a leash. Dorba Trail Dorba Trail sign, Cedar Hill State ParkThe Dorba trail was primarily created through the efforts of the Dallas Off Road Bicycle Association. They worked closely with Cedar Hill State Park management to help design and build this trail. Their efforts ened up returning a big dividend for off road bicyclists as the trail is now considered on the top mountain bike trails in the state. Dorba Trail, Cedar Hill State ParkDorba has has three loops: Short (2.5 Miles), Middle (7 Miles) and Outer (10+ miles). The paths pass through wooded areas but are fairly open for much of their length. Having the sun beating down on you can make a warm summer hike considerable warmer – be sure to plan ahead and bring an adequate amount of water with you. The trail is what you might expect from a design made for mountain biking. There are plenty of twists, turns, and ups and downs. None of this is too strenuous but if you are looking for an easy, short hike you will be better of using one of the other three trails.
