Fathom Five National Marine Park

Dolomite, 420 million years old, rises through the sparkling waters of Lake Huron to form Fathom Five National Marine Park. This is a freshwater ecosystem of ancient rock formations, grassy cliff-edge forests, fascinating dive sites on 22 shipwrecks, and orchid species both plentiful and rare.

Visit for a day or backcountry camp on starry-skied Flowerpot Island—Fathom Five is equal parts mystery and recreation, ecology and culture—and a welcoming escape to nature.
