It lies on the state's southern coast, about 6 miles south of Port Orford and 21 miles north of Gold Beach. The mountain is completely within Humbug Mountain State Park, and U.S. Route 101 passes by its northern base. Its slopes feature an old-growth temperate rainforest. Two trails run from the state park campground to the mountain's summit, one 1.5 miles long, the other 2 miles long. Both are part of the much longer Oregon Coast Trail. The area is popular with hikers, campers, cyclists, and whale watchers although biking and camping on the mountain itself are prohibited.
