About Arch Rock
Arch Rock is a limestone arch formed by water and ice erosion over thousands of years on the cliff on the east side of Mackinac Island. The opening, roughly 15 meters wide, frames the blue water of Lake Huron about 45 meters below.
For Anishinaabe peoples, the island and its formations feature in traditional stories, and the arch is one of the park’s most visited spots. A wooden viewing platform sits above, accessible via the island’s interior roads.
From lake level, a staircase leads from the lakeside road up near the arch for those arriving by bicycle.
