AUGUSTA — Maine State Parks and Historic Sites will treat Maine residents to free admission on Father's Day, which is this Sunday, June 21. This annual gesture is meant to show appreciation for Maine residents for their continued support of Maine State Parks and Historic Sites. All vehicles bearing Maine license plates on Father's Day will be granted free-admission at all 48 state-owned and operated locations, according to Maine Department of Agriculture, Conservation and Forestry's Bureau of Parks and Lands.

The open admission does not apply to the AWW, Baxter State Park, the Maine Wildlife Park, Peacock Beach, Scarborough Beach, Swan Island, or the Penobscot Narrows Observatory in Prospect, though admission to Fort Knox State Historic Site will be free that day.
