You Can Hunt For Michigan’s State Stone At These 10 Great Lakes Beaches
My grandmother handed me my first Petoskey stone when I was seven, plus I have been hunting for them along Great Lakes beaches ever since. The hexagonal patterns pressed into the surface are coral from an ancient sea that covered this part of the continent millions of years ago.
Finding one yourself is different from buying one in a gift shop. You walk the wet sand after a storm, flipping stones with your toe, checking the undersides where the pattern shows best.
Beaches across the state have earned reputations as prime hunting grounds.
Some sit near resort towns. Others require a drive down dirt roads to reach shorelines that feel untouched by anyone but the waves.
The hunt becomes addictive once you spot your first hexagon in the sand. After every storm, Michigan shorelines reveal Petoskey stones that patient walkers know exactly how to find.
1. Petoskey State Park
Wet gravel does most of the identification work for you along this famous stretch of Little Traverse Bay.
The park at 2475 M-119 Highway, Petoskey, MI 49770 has roughly a mile of Lake Michigan shoreline, and the Michigan DNR specifically identifies it as a popular place to search for Petoskey stones. That makes it an excellent first stop if you are still learning what the state stone looks like in the wild.
Walk where the waves repeatedly wash over bands of small rocks rather than concentrating only on dry sand. Unpolished Petoskey stones can look disappointingly plain when dry, but water darkens the limestone and makes the individual coral cells much easier to recognize.
The geology is ancient even though the rounded shape is not. Petoskey stones are fragments of colonial coral that lived roughly 350 million years ago, while glaciers and later wave action broke, transported, and polished the pieces into the smooth stones found today.
There is more here than rock hunting. The park has two modern campgrounds, dune landscapes, the half-mile Old Baldy Trail, and connections to regional trails.
A Recreation Passport is required for Michigan vehicles entering the state park.
For collecting, remember the state-land limit of 25 pounds per person per year.
2. Magnus City Park Beach
Downtown Petoskey remains close enough to see, but your attention quickly drops toward the gravel.
Magnus Park offers around 1,000 feet of Little Traverse Bay shoreline and is one of the local spots specifically recommended by the Petoskey Regional Chamber for state-stone hunting. The park is at 901 West Lake Street, Petoskey, MI 49770, making it unusually convenient for anyone who wants to combine beachcombing with restaurants, shops, and the rest of the waterfront.
The best strategy is slow movement.
Follow the wet edge of the lake and scan stones before picking anything up. The distinctive Petoskey pattern consists of tightly connected coral chambers, usually with a central point and radiating lines inside each cell.
Wetting a promising dry stone with a small spray bottle can save you from carrying fifty ordinary gray rocks around all afternoon.
Magnus is also a campground, with dozens of sites overlooking or sitting close to Little Traverse Bay. That means the beach can feel busier than more remote stops, particularly in summer.
3. Fisherman’s Island State Park
Six miles of mostly undeveloped shoreline give you considerably more room to search than the name “island” might suggest.
This 2,678-acre state park begins at 16480 Bell’s Bay Road, Charlevoix, MI 49720 and stretches along a wild section of Lake Michigan coast south of Charlevoix. The DNR specifically notes that its rocky shoreline is popular with Petoskey stone hunters.
The landscape feels much rougher than a municipal swimming beach.
Pebbles, driftwood, forest, dunes, and sections of stone-covered shoreline replace groomed sand, which is exactly why rockhounds like it. Petoskey stones can turn up alongside Charlevoix stones, another fossil coral with a noticeably tighter pattern of smaller cells.
Look in freshly washed gravel after calm has returned following a windy period. Winter ice and strong waves constantly rearrange the shoreline, meaning a section that looked picked clean during one visit can look completely different later.
Good footwear matters here.
The rocky shore can be tiring on ankles, and quieter stretches require more walking than urban beaches. Bring water too, since services become sparse as you move away from the developed day-use area.
The rustic campground closes September 15 for the remainder of the 2026 season because of culvert work, but the park itself remains a worthwhile shoreline destination.
4. Mt. McSauba Recreation Area And Beach
Six miles of mostly undeveloped shoreline give you considerably more room to search than the name “island” might suggest.
This 2,678-acre state park begins at 16480 Bell’s Bay Road, Charlevoix, MI 49720 and stretches along a wild section of Lake Michigan coast south of Charlevoix. The DNR specifically notes that its rocky shoreline is popular with Petoskey stone hunters.

5. Lake Michigan Beach In Charlevoix
A lighthouse, downtown streets, and a surprisingly productive stone beach all fit within the same easy walk here.
Michigan Beach Park sits at 95 Grant Street, Charlevoix, MI 49720, offering roughly 2,000 feet of Lake Michigan frontage near the channel and Charlevoix South Pier Light. Local tourism information specifically lists Petoskey stones among the attractions found along the shore.
That makes this one of the easiest hunting grounds on the list for beginners.
The beach contains both sandy stretches and areas where wave action collects gravel, so concentrate on those pebble bands rather than pacing the cleanest sand. Search just inside the wash zone, where stones remain wet enough for fossil patterns to show naturally.
You may also find Charlevoix stones.
They are another type of fossil coral but usually have smaller, tighter cells than the broader hexagonal chambers associated with classic Petoskey stones.
The park is unusually well equipped for a rockhounding stop, with restrooms, an accessible beach mat, playground, pavilion, walking paths, and easy access to downtown.
6. North Point Nature Preserve
The search feels quieter here because the beach is only one part of a much more sensitive landscape.
North Point Nature Preserve begins along McSauba Road, Charlevoix, MI 49720, immediately beside the Mt. McSauba recreation area.
The preserve protects roughly 28 acres of wooded dunes and undeveloped Lake Michigan shoreline, with about 1.5 miles of trails winding between forest, sand, and overlooks.
Petoskey stones can be spotted along the shore, and regional tourism guides include North Point among Charlevoix’s better-known hunting locations.
This is a place where I would emphasize looking over collecting.
The preserve protects threatened plants including Pitcher’s thistle, Lake Huron tansy, and Pumpell’s bromegrass. Those species survive in a narrow coastal habitat where trampling can do real damage, so use the established trails and avoid wandering through dune vegetation simply because a patch of beach looks easier to reach that way.
Once on the shoreline, scan wet gravel close to the water.
A compact magnifier is useful if you want to compare fossil structures without pocketing every candidate. You may see Petoskey stones, smaller-patterned Charlevoix stones, and other fossil fragments mixed among ordinary limestone and glacial rocks.
The undeveloped atmosphere makes this especially satisfying after busier Charlevoix beaches.
7. Point Betsie Lighthouse Beach
Few Petoskey stone hunts come with a better object on the horizon.
The red-roofed lighthouse at 3701 Point Betsie Road, Frankfort, MI 49635 has stood beside Lake Michigan since the nineteenth century, and the public beach around it is one of the better-known rockhounding locations in the Frankfort area.
Mixed gravel accumulates along stretches of shoreline where waves constantly rearrange the stones.
That movement is exactly what fossil hunters want.
Petoskey stones are easier to identify when wet, so work slowly along the waterline and let the lake reveal patterns for you. After a period of strong waves, newly exposed gravel can contain stones that were buried beneath sand only days earlier.
The setting adds plenty even when the search is slow.
Point Betsie first entered service in 1858, and the lighthouse remains open for seasonal tours in 2026 from May 16 through October 11 on its published schedule. The surrounding dunes are also environmentally significant, supporting threatened Great Lakes plants.
Free parking is available near the lighthouse, although summer traffic can stretch along the road.
Stay off fragile dune vegetation and give rough water more respect than your search instinct.
A good Petoskey stone will still be there once the waves calm down.
8. Frankfort Public Beach
Soft sand dominates at first glance, but the gravel mixed along the waterline tells a more interesting geological story.
Frankfort Public Beach sits at the west end of downtown around Fr. Marquette Circle, Frankfort, MI 49635, with Lake Michigan spreading beyond the pier and North Breakwater Lighthouse.
Michigan geological guidance specifically identifies Frankfort’s public shoreline as a known fossil-hunting locality.
That does not mean Petoskey stones will be sitting in neat piles.
You have to look for the areas where the lake has concentrated pebbles among the sand.
Freshly washed bands near the surf are best because moisture exposes fossil structures. Petoskey stones show larger connected coral chambers, while other fossil corals may appear as dots, chains, or tighter honeycomb patterns.
The beach is unusually easy to incorporate into a town visit.
Downtown Frankfort begins only a few blocks away, and the park has public restrooms, seating, accessible paths, and a broad stretch of shoreline.
Wind direction can transform the hunting conditions from one day to the next.
A calm beach may expose little gravel, while recent waves can uncover an entirely new strip.
9. Empire Beach
The stones here compete with the scenery for attention.
Empire Beach Village Park is at 10484 Niagara Street, Empire, MI 49630, just a block from the center of the village and immediately west of Sleeping Bear Dunes National Lakeshore. The beach is public village property rather than part of the national lakeshore, an important distinction because federal rules prohibit removing stones from Sleeping Bear beaches.
Along Empire’s shoreline, mixed glacial rocks and fossils can appear wherever waves expose gravel beneath the sand.
Petoskey stones are possible, but this is also an excellent place to practice identifying the wider variety of Michigan beach geology. You may encounter igneous stones carried south by glaciers, colorful metamorphic material, limestone, and several kinds of fossil coral.
Wet everything suspicious.
A stone that looks blank when dry can reveal a crisp fossil pattern the moment water crosses its surface.
The park also has a playground, picnic facilities, grills, potable water, restrooms, and the small Robert H. Manning Memorial Lighthouse near the boat launch.
Be especially aware of boundaries if you walk farther along the coast.
Once you enter Sleeping Bear Dunes National Lakeshore, rocks and fossils must remain where you find them.
10. Peterson Park
Your reward for descending the long staircase is one of the rockiest beaches on the list.
Peterson Park sits at 10001 East Peterson Park Road, Northport, MI 49670, on the western side of the Leelanau Peninsula. From the parking area above the bluff, a viewing platform looks across Lake Michigan before stairs drop to roughly 1,000 feet of public shoreline.
Unlike broad sandy swimming beaches, this coast is loaded with cobbles.
That makes it excellent terrain for a careful Petoskey stone search. The Michigan Mineralogical Society lists Peterson Park among the region’s known state-stone locations, and local rockhounds also report Charlevoix stones, chert, and other interesting material here.
Wet surfaces make everything easier.
Look for the broad hexagonal coral cells of Petoskey stones and compare them with the much smaller packed circles of Charlevoix stones. Chert, meanwhile, often appears smoother and waxier without the organized fossil structure.
The physical challenge is worth remembering.
Loose cobbles make walking slower than the distance suggests, and anything you carry down eventually has to come back up the staircase. There is an accessible overlook, pavilion, playground, picnic area, restrooms, and paved parking above the beach.
