Huron Islands Wilderness

The Huron Island Wilderness is located on and makes up the entirety of the Huron National Wildlife Refuge. Created when President Theodore Roosevelt designated the small islands a national bird sanctuary to protect large colonies of nesting gulls, all eight of the Refuge’s islands are now managed as wilderness. Of these islands, only Lighthouse Island is open to public access. The eastern-most island is known as Cattle Island in memory of the livestock marooned there in 1860 when a cargo ship, the Arctic, ran aground. This incident prompted the construction of a lighthouse on the Lighthouse Island, also known as West Huron Island. The lighthouse was completed in 1868 and remains active within the Wilderness.
