G. Richard Thompson Wildlife Management Area is located primarily in Northwestern Fauquier County, Virginia and with portions in Clarke and Warren Counties. It is located within the Blue Ridge Mountain range and elevations range from 700 to 2200 feet.
The 10-acre Thompson Lake is a major feature of the WMA and popular place for family recreation. Public fishing is available and the lake is stocked with trout. The lake drained in 2008 and 2010, which has depleted other fish species. A small boat launch provides boating access to the lake.
Hiking is a popular activity within the park and there are 7 miles of the Appalachian Trail within the Thompson WMA.
Thompson WMA is known for its Spring wildflowers, especially its large stands of trillium that are considered the largest on the East Coast.
