crsytal bay sea cave on lake superior near tettegouche state park

Crystal Bay Sea Cave

mile 58.9
Length: 0.2 miles Difficulty: moderate to difficult due to unkept trail

 

Crystal Bay is a little crescent of loveliness on calm days. The short, steep path contains loose rock and can be a slippery when dewy or after rains. You will see some old concrete blocks that were part of the original structures built in 1902 when (now global) 3M began their operations. The beach is small cobbled stone with one of Lake Superior’s largest sea caves to the north and cliffs to the south. You need a boat to get to the cave but can easily see it from the beach. On wild and windy days – especially during the gales of November – the nor’easters drive waves into the southern wall, making for mammoth crashing waves. This is safest viewed along Highway 61. Park off the shoulder of the highway near mile marker 60 on the northeast side of Crystal Creek. Take the path on the right/south.
