Arch Rock
A natural limestone arch rising about 44 m above the lake, through whose opening you can glimpse the deep blue of Lake Huron. It is the most famous natural landmark on Mackinac Island.
Arch Rock is a natural limestone arch formed by dissolution. It spans about 15 m, and its top rises about 44 m above Lake Huron. Through the opening you can see the bright blue water below. It has been an iconic island sight since the 19th century and is also linked to Ojibwe legends. You can view the arch level from a lookout in the island's central heights, or climb the roughly 200 wooden steps beside the M-185 road to look up at it. Admission is free. Bicycling from downtown takes about 10 minutes, and carriage tours stop here too. Autumn foliage makes the view especially beautiful.
