Maine residents will be recognized this coming Sunday, Father’s Day, for their continued support of Maine state parks and historic sites with a free-admission day at all 48 state-owned and -operated locales, according to Maine Bureau of Parks and Lands (BPL) officials, under the Maine Department of Conservation.

“From birding at Aroostook State Park to baking bread in the Civil War vintage oven at Fort Knox to welcoming summer at Roque Bluffs among the rugosa roses, it will be a great day to take Dad out for an outing,” said Commissioner Bill Beardsley of the Maine Department of Conservation in a news release.

“This is a great way to start the summer season with a free trip to your favorite state park or historic site,” Will Harris, BPL director, said. “We hope to see many Mainers out enjoying their Father’s Day with us.”

The details of the free parks admission are:

9 a.m to 6 p.m., all vehicles bearing Maine license plates will be allowed free entrance to Maine state parks and historic sites. No rain date will be available. The open admission does not apply to the Penobscot Narrows Observatory in Prospect, though admission to Fort Knox State Historic Site will be free that day.
