Petoskey State Park
Michigan’s Premier Fossil-Hunting Beach on Little Traverse Bay
Petoskey State Park sits on a crescent of sand along Little Traverse Bay, roughly 3 miles northeast of downtown Petoskey and 6 miles south of Harbor Springs. Its mile-long beach is one of the most reliable spots in the world to find Petoskey stones — Michigan’s official state stone — fossilized Hexagonaria percarinata coral that’s roughly 350 million years old. Wave action continuously tumbles new specimens onto the shore, making every visit a treasure hunt.
Beyond the stones, the park delivers towering coastal dunes, two well-equipped campgrounds, and direct access to the 26-mile Little Traverse Wheelway — a paved trail that connects Charlevoix and Harbor Springs. Whether you’re here for a geology lesson, a sunset beach walk, or a multi-day camping trip, Petoskey State Park punches well above its 305-acre weight class.
🪨 The Complete Petoskey Stone Guide
Petoskey stones are fossilized rugose coral colonies. Each stone contains tightly packed, six-sided cells (corallites) with a signature dark “eye” at the center and radiating lines — a honeycomb pattern that becomes vivid when the stone is wet. Dry, they look like ordinary gray limestone, which is why experienced hunters carry a spray bottle.
🔍 Stone-Hunting Pro Tips
- Best time: Early spring after ice-out, during rain, or right after a storm — wave action deposits fresh stones
- Where to look: Walk the waterline slowly; check gravel patches and rocky areas near the beach ends
- Identification trick: Spray or dip stones in water — the hexagonal coral pattern will instantly appear
- Collection limit: 25 pounds per person per year from state parks
- Polish at home: Many Petoskey-area shops sell polishing kits, or use 220-grit then 600-grit sandpaper
