Agate Beach

Agate Beach is a public beach on Lake Superior's shoreline in Michigan's Upper Peninsula, stretching roughly 2 miles along the water. The shores feature natural rock formations and tidal pools that create the beach's distinctive character.

The beach took shape through thousands of years of Lake Superior's waves and erosion, which sculpted the rock and exposed minerals. This geological history created the mineral deposits that define the shoreline today.

The beach draws collectors and amateur geologists who search for semi-precious stones among the rocks and shoreline. Visitors often combine a walk here with the hunt for special minerals that line the water's edge.

The beach is accessible from the parking area via marked trails and is open from sunrise to sunset. Wear sturdy shoes, as the terrain with rocks and uneven ground can be challenging underfoot.

Strong storms wash deposits of chalcedony and semi-precious stones onto the shore, making it popular among mineral collectors. Visitors often report finding more stones than usual after such weather events.
