Sea Caves

The Sea Caves are the ultimate destination for an Apostle Island Adventure

We will get you into the Sea Caves like no one else

Within the Apostle Islands National Park there are many sets of Sea Caves.  The most popular are found on Sand Island, Devils Island and along the shore of the Mainland in Mawikwe Bay near Meyers Beach.  There are also many others through out the islands.  Check them out on our map by clicking the sea caves tab found along the top. 

Mawikwe Bay "Mainland" Sea Caves

Famous for the Ice Caves, the largest set of sea caves is just a short jaunt from our Cornucopia location.

This tour lasts 1.5-2 hours and the trip though the youngest rock formation in the Apostles is incredibly breathtaking.  We have been offering this tour since 2012, longer than any other company and we can navigate through the caves better, giving you the most intimate experience you can get on a power boat tour. 

Sand Island Sea Caves

The Caves on Sand are a smaller version of the type of caves you can see at Devils Island.  The formation here is more thinly laminated and denser than that found in the Orienta Formation of Mawikwe Bay, making them much more showy.  There are more pillars and tunnels in the Devils Island formation making it a hot spot for kayak exploration. 

A tour to Sand Island departs from Cornucopia and lasts approximately 3 hours. This includes the mainland caves as well as the Sand Island Caves and Lighthouse.

Devils Island Sea Caves

 

If you can get there just go.  It is incredible. The Devils Island formation is ancient sand flat deposits with shallow ponding on it.  This is what created the layering that makes these caves so unique. 

About 25 miles out from Bayfield, a 4 hour tour to Devils Island will take you right through the heart of the Apostle Islands viewing most of them on the way.  This trip is rich in history, geology, and beauty and includes multiple island stops where you can get out and explore on foot.
