Dark Sky Island

55 sq miles of isolated darkness in the northern reaches of Lake Michigan

Beginning at sunset, deepening into evening’s rosy dusk, Beaver Island delivers all the glories of the night sky on an unmatched canvas of black. The Milky Way, meteor showers, galactic events, satellite flares, the Northern Lights and more. All in an atmosphere of quiet peace, little traffic, scenic areas, trails and waterways that mark your path to discovering the joy of relaxing under the stars.

Welcome to the dark side.

The Milky Way in full view as a soft breeze passes through. Saturn and Jupiter welcome you to the night, their glow providing the perfect path for nature to find its way. Constellations known and new introduce themselves as you gaze into the dark sky. Quiet. Silence. Darkness.

Welcome to Beaver Island, Michigan.

Our Mission

We believe that darkness brings light, life, and health. Every decision made by every individual, whether a resident or a visitor, can positively or negatively affect the many delicate ecosystems on Beaver Island. By treasuring its complexities and respecting its fragility, we can protect life that thrives under dark skies through proactive communication, education, training, and structure.

The Proposed Beaver Island Dark Sky Sanctuary

The prestigious International Dark Sky Sanctuary designation is held by only 14 locations in the world, 7 of those in the United States and only one other on an island. This certification would increase awareness and the growing need for education around the importance of maintaining the island’s dark skies while ensuring that the island’s natural resources, wildlife, and ecosystems are protected.

We’re proud of our numbers.

Beaver Island is unique in many ways. Our location in an inky dark spot in the middle of northern Lake Michigan gives some of the darkest night skies in the world. Sky quality measurements (SQM) are measured on a scale from 16 to 22 with 16 indicating maximum light polution and 22 indicating the absence of all light polution. Readings all over the island are consistently exellent.

Knowledge is Power

Light Pollution is a hazard to your health

For most Americans, the night sky is getting ever brighter. This causes significant harm to the health of human beings, animals and the ecosystem as a whole.
