Castle Rock, Limestone stack summit in St. Ignace, United States.
Castle Rock is a limestone formation in St. Ignace that rises 195 feet above Lake Huron, providing a natural vantage point for viewing the surrounding water. Outdoor stairs lead to the summit, where an observation platform sits at the top.
The Eby family purchased this geological site in 1928 and developed it into a tourist destination. The location has operated continuously since then, becoming part of the region's early tourism history.
The site displays statues of Paul Bunyan and Babe the Blue Ox, linking Michigan's geological character with American folklore. These figures shape how visitors experience the location and its connection to regional stories.
Access is available from May through October when the outdoor stairs are open to visitors. Be aware of weather conditions, as wind and moisture can affect stair safety during your climb.
The gift shop features walls and ceiling crafted from birch bark by Native Americans during the 1950s. This rare handwork remains in place today, offering a window into traditional techniques that visitors encounter inside.

Michigan holds a wide array of natural and historical sites across its two peninsulas. The shoreline runs for hundreds of miles along the Great Lakes, showing sand beaches, rocky cliffs, and dune formations. In the north, dense forests, waterfalls, and rock formations shaped by erosion dominate the landscape. Lighthouses from the 19th century mark key points along the waterways. Historical sites document the region's development, from military posts to industrial monuments. Visitors can explore places like Pictured Rocks, where colored sandstone cliffs rise directly above the water, or Sleeping Bear Dunes, where sand piles up to 450 feet (137 meters) high. Mackinac Bridge connects the two peninsulas with a span of roughly 5 miles (8 kilometers). At Hartwick Pines State Park, pine trees stand several centuries old. Tahquamenon Falls ranks among the larger waterfalls east of the Mississippi. On Mackinac Island, Fort Mackinac dates to the 18th century, while the Heidelberg Project in Detroit presents contemporary art in an urban setting. This collection presents both natural and human-made sites across a region that stretches over both of Michigan's peninsulas.
