Emerging from the clear waters of Lake Superior are the colorful golden red arches of the Apostle Islands sea caves. You'll find the caves on the outer shoreline of several of the islands. The delicate, arching caves were formed by the weathering action of Lake Superior's wind and waves on the sandstone shoreline. Oxidized iron in the rock gives the caves a burnt orange, rusty color. Some of the caves feature a rippling pattern in the rock, formed by the same weathering action, nearly a billion years ago.
Because the caves are located at the base of steep cliffs that drop straight into the lake, they are accessible only by boat. Perhaps this limited access is what makes them special, as they offer a place to enjoy the solitude and powerful beauty of the Apostle Islands and Lake Superior.
During periods of extremely calm weather, it's possible to paddle into the caves to explore their beauty and intriguing sounds. Sea caves can be both seen, and heard. The action of the waves pouring through the caverns causes the caves to sound deep, percussive notes.
Devil's Island and Sand Island are home to some of the most dramatic and colorful sea cave formations. Getting to Devil's Island by kayak typically entails a multi-day expedition. Self-supported or guided kayak tours to the island can be arranged though outfitters in Bayfield, including Trek and Trail (trek-trail.com) or Living Adventures (livingadventure.com). Because Devil's Island is exposed to weather from the open lake, arranging a visit to the caves requires a combination of good weather, a knowledgeable guide, and solid boating experience.
If your time is limited, consider visiting the caves on Sand Island, or the caves east of Meyers Beach. Sand Island is much closer to the mainland compared to Devil's Island, and the shoreline surrounding the caves offers more protection from the weather. Meyers Beach is accessible from the mainland, and the caves are a one-mile paddle from the parking lot.
Boating on Lake Superior is a serious endeavor, and you should only venture out into the lake with an experienced guide or captain. Even if you already have extensive boating experience, it is advisable to check with the National Park Service, local kayak companies, or sailing charter operators prior to getting on the water. A sudden change in the weather can turn a relaxing paddle to the sea caves into a fight for survival, as the steep, rocky shoreline of the cave area offers no protection from wind or waves.
