Residents Appreciation Day Posted November 3, 2023 For residents of Mackinac, Cheboygan, or Emmet counties, for one weekend, we discount the admission prices for all of our sites to what they were when we first began operating our modern museum programs for the public in 1958. (.50 cents adults, .25 cents children). Thank you for supporting Mackinac State Historic Parks! This special offer includes residents of Mackinac, Cheboygan and Emmet counties. Proof of residency is required (e.g. driver’s license).
