Birch Hill Wildlife Management Area encompasses 7,431 acres in Royalston with diverse habitats including conifer-hardwood forests, open fields, brush lands, and marshes, offering hiking, fishing, and wildlife observation opportunities.

The area features the Otter and Millers Rivers (both stocked with trout), smaller cold-water streams with native trout, and access to multiple recreational trails and snowmobile routes.

Two state-operated campgrounds—Lake Dennison (150 sites) and Otter River State Forest (100 sites)—provide camping facilities for visitors exploring this expansive management area.
