Green Ridge Forest State Park is one of the largest state forests in Maryland, spanning 47,000 acres. The park boasts numerous hiking trails, fishing along the Potomac River, and hunting.
There are 100 primitive campsites throughout the forest, each equipped with a picnic table and fire ring. To use a campsite, you must register in person at the forest headquarters at 28700 Headquarters Drive NE, Flintstone, MD 21530. The fee to stay is $10 per night, payable only in cash or check.
Named for the Mertens family, who in the late 1800s converted much of what is now the GRFSP to apple orchards, Mertens Avenue is a 6-mile-long dirt road that connects the east side of the forest to Green Ridge Road. There are two regular campsites along the trail and 1 group campsite. Banner's Overlook, about halfway through the trail, looks east towards West Virginia. The trail is easy for all vehicles.
