Colonial Michilimackinac is a National Historic Landmark, and is home to North America's longest ongoing archaeological dig. Costumed interpreters portraying British soldiers, merchants, voyageurs, Native Americans, and other tradespeople are on site daily, providing demonstrations, tours, and programs. Colonial Michilimackinac also offers unparalleled views of the Straits of Mackinac, Mackinac Bridge, and Mackinac Island. During the summer months, weather permitting, archaeologists are on site, digging through the layers of soil, pulling out bits of history in front of you.

Old Mackinac Point Lighthouse was known as the "Castle on the Straits" upon its completion, and it's not hard to see why. The house and grounds are being restored back to its 1910 appearance, and interactive exhibits and galleries, informative demonstrations, and tours of the tower allow guests the opportunity to step back int time and see what life was like for keepers and mariners at the turn of the 20th century.
