Access is exclusively by private boat or by a seasonal ferry service operated by the Thousand Islands Park and Recreation Department. Parking is available in Clayton at the municipal marina. No public transport directly serves the island.

Historical & Ecological Origin

Construction of the lighthouse was completed in 1847. It was built to guide ships through the treacherous waters of the Thousand Islands. The island itself is composed of Precambrian bedrock, characteristic of the Canadian Shield geological formation.

Facts & Legends

A notable historical detail is that the original keeper's dwelling, built concurrently with the lighthouse, was later demolished. A local anecdote suggests that during severe storms, the foghorn's sound could be heard for miles, leading some to believe it was a mournful cry.
