The section of trail along the backside of the lake will be closed for walking and the dam area will be inaccessible for boating and fishing. Visitors should follow posted signage and use alternate trail routes until work is complete.
Eleven miles of hiking trails meander through a variety of wildlife habitats and afford a view of the area's geological history.
Most of Greenbriar’s trails are classified as moderate to strenuous, so be prepared for some fairly steep hills and rocky terrain.
You will need appropriate footwear (the trails can be very rocky), clothing and gear, including drinking water.
Each campsite is equipped with a table, fire ring and parking area. Fires must be kept inside the fire rings. A dump station is available.
