Bathtub Island is located near Katherine Cove in Lake Superior Provincial Park in Ontario’s Algoma Country. The island is suitably named due to the basin like impression that fills with water when Lake Superior’s waves become high enough to reach it creating a natural “bathtub”. To reach the island, follow the coastal trail from Katherine Cove about 0.31 miles (.5km) south. Once you get to the shore the water is shallow and sand is soft enough that you can easily walk out to the island just off the shoreline. The island is made of smooth rock that can get very slippery to climb onto. It is short yet demanding hike with the reward of a satisfying soak in a bathtub overlooking Lake Superior.
