The Hudson Gorge Primitive Area (HGPA) encompasses approximately 17,000 acres of State Forest Preserve in Essex and Hamilton Counties. It is located north of State Route 28 between the hamlets of Indian Lake and North River, near the center of the Adirondack Park.

The steep-sided Hudson Gorge is one of the most spectacular reaches of the Hudson River. Whitewater rafting through the gorge is the most popular recreational activity in the primitive area. With limited foot trail access, the interior of the area offers great opportunities for hiking, camping, hunting, fishing and trapping in a wild setting. Most visitors to the primitive area have been customers of whitewater rafting outfitters, who have led rafting trips between the Lake Abanakee dam on the Indian River to the hamlet of North River on the Hudson, 16 miles away.
