Located in northern Wisconsin, the Apostle Islands National Lakeshore Mainland Sea Caves offer an extraordinary glimpse into the raw power and beauty of nature. Carved into sandstone cliffs, these intricate cave systems are a picturesque marvel, presenting a perfect blend of stunning geology and the serenity of vast, open waters.

History The Apostle Islands were formed by the forces of glaciers, waves, and weather over millions of years. The sandstone, the primary geological feature of the islands, is easily eroded by wind and water, leading to the creation of the stunning sea caves. These natural marvels have attracted human beings for centuries, from early Native American tribes to contemporary explorers and tourists.

How to Get There The Apostle Islands Mainland Sea Caves are accessible from the Meyers Beach Road, off Highway 13, about 5 miles east of Cornucopia, Wisconsin. The parking lot is an additional mile down Meyers Road. The sea caves can be visited by kayaking during the summer months, and in winter, when Lake Superior freezes over, via a marked trail over the ice (conditions permitting).

List of Attractions

  1. Kayaking: Paddle along the coast to explore sea caves, arches, and hidden chambers.
  2. Ice Caves: Visit in cold winters when the caves transform into a wonderland of ice formations.
  3. Hiking: Trails along the cliffs provide tremendous views of Lake Superior and the sea caves.
  4. Wildlife Viewing: Spot a myriad of birds, and occasionally mammals like bears and wolves.
  5. Photography: Capture the astonishing natural beauty in every season.

Ticket Information Visiting the Apostle Islands National Lakeshore is free; however, some amenities or services may require fees, such as camping or docking overnight in the park. Also, during the winter season, there is a user fee for access to the Ice Caves.
