Trailway
The Lake Somerville Trailway connects Birch Creek and Nails Creek units via trail around the west end of Lake Somerville. The Trailway’s 26 miles of interconnected trails and loops let you explore the shoreline.
Those miles of trail cross through yaupon, post oak, hickory, blackjack oak and water oak forests, and pass scenic overlooks and water crossings.
All trails are open to hikers, mountain bikers and horseback riders. Please be courteous to other trail users.
Note: Obtain permits at either unit's headquarters. Equestrian parking for the Trailway is permitted at the access gate on CR 125 and CR 140. Contact the park for the most recent information.
Access the primitive group camping areas along the Trailway. Fires are allowed in established fire rings. This site does not have potable water. Several chemical toilets are along the trails.
Well water for horses (not humans) is at Newman Bottom and Wolf Pond.
Flag Pond
Follow the Trailway about 4 miles from Nails Creek Unit (9 miles from Birch Creek) to Flag Pond, home to birds and other wildlife.
The pond is a 350-acre impoundment in the Yegua Creek watershed. It’s a natural depression which serves as wetland habitat for waterfowl in the winter. A private hunting club originally developed the pond in 1926.
A system of trails and the Flag Pond Observation Center surround the pond today. You can view wildlife and take photographs from all angles.
