Petoskey State Park

Petoskey State Park sits on the shore of Little Traverse Bay between Petoskey and Harbor Springs in Emmet County, a beautiful Lake Michigan beach park in the heart of northern Michigan’s resort country. Its sandy beach, low dunes and clear bay waters make it a classic summer destination — but the park is especially famous for one thing: hunting Petoskey stones.

These fossilized coral pebbles, the official state stone of Michigan, wash up along the bay’s shore, and combing the beach for their distinctive hexagonal pattern is a cherished tradition that draws rock hounds and families alike. Beyond the stone hunting, the park offers swimming, dune trails, a campground and sweeping views across Little Traverse Bay, all within easy reach of the charming towns of Petoskey and Harbor Springs. Petoskey State Park is a quintessential northern-Michigan beach experience.

The park’s sandy Little Traverse Bay beach is the centerpiece — swimming, sunbathing and, famously, hunting Petoskey stones along the shore. Dune trails climb the wooded dunes for bay views, and a campground serves overnight visitors. The clear, often calmer bay waters are pleasant for paddling and wading, and the park’s setting between Petoskey and Harbor Springs makes it an easy base for exploring northern Michigan’s resort towns, beaches and trails.

Summer is peak, with warm bay water for swimming and the beach in full swing — reserve campsites early. Spring and fall are prime for Petoskey-stone hunting, when storms and waves churn up fresh stones and the beach is quieter; wet stones show their pattern best. Fall brings color to the surrounding hills, and winter leaves a quiet, snow-dusted shore. Time a visit for stone hunting in the shoulder seasons or summer beach days.

The park was established to preserve public access to the Little Traverse Bay shore in the heart of northern Michigan’s historic resort country, where Petoskey, Harbor Springs and Bay View have drawn summer visitors since the 19th century. The Petoskey stone — named for the area and designated Michigan’s state stone — has long made these beaches famous, and the park celebrates and protects that tradition along with the bay’s natural beauty.

Petoskey stones are fossilized colonial coral that lived in the warm seas covering Michigan some 350 million years ago; later ground and scattered by glaciers and now tumbled smooth by Lake Michigan’s waves, they wash up along Little Traverse Bay with their distinctive hexagonal ‘eye’ pattern. The park’s low dunes and sandy beach sit on the glacially shaped shore of the bay, part of the limestone-rich geology that makes the region a treasure trove of fossils.

The beach, dunes and surrounding forest host white-tailed deer, fox and a variety of birds, with Little Traverse Bay and the Lake Michigan shoreline drawing waterfowl, gulls and migrating songbirds and raptors. The dune grass and wet sand host shorebirds, and the bay’s clear waters support fish. The park’s setting on the migratory shore makes for pleasant birding alongside the stone hunting and beach days.

The park protects a stretch of Little Traverse Bay dune-and-beach ecology, from the pioneer marram grass of the foredunes to the forest on the stabilized dunes. The fragile dunes are easily damaged, so staying on trails matters. The bay’s clear waters and the fossil-rich shore are part of the limestone-influenced ecosystem of the region, where geology, water and habitat combine to create the famous Petoskey-stone beaches.

Petoskey State Park is woven into northern Michigan’s identity, its beach the most famous place to hunt the Petoskey stone — the state stone and a beloved symbol of the region. Set amid the historic resort towns of Petoskey and Harbor Springs, with their Hemingway connections and Victorian charm, the park anchors a quintessential northern-Michigan summer tradition of beach days and stone hunting on Little Traverse Bay.

Petoskey State Park is on Little Traverse Bay between Petoskey and Harbor Springs in Emmet County, reached via M-119 off US-31. A Michigan Recreation Passport is required. The beach, dune trails, campground and day-use areas are within the park, with easy access to the towns of Petoskey, Harbor Springs and Bay View. The bay-shore setting makes it a convenient base for exploring the region.

The DNR manages Petoskey State Park to protect its dunes, beach and bay shore while supporting heavy summer recreation and stone hunting. Visitors help by staying on dune trails to protect the fragile vegetation, honoring any shorebird-nesting closures, taking only a reasonable number of Petoskey stones (collecting limits apply on state land), and packing out litter. Protecting the dunes and shore preserves both the beach and the famous stone-hunting tradition.

Little Traverse Bay is often calmer than the open Great Lakes, but Lake Michigan can still build waves and currents — heed conditions and supervise swimmers. The water is cold outside summer. The dune trails are sandy and hilly; wear sturdy shoes. Bring sun protection for the open beach, and watch footing on wet, slippery stones while hunting. Supervise children near the water and on the dunes.

A Recreation Passport is required. Collecting Petoskey stones is allowed within state collecting limits (generally a modest amount per person per day on state land) — follow current DNR rules. Stay on dune trails to protect vegetation. Pets must be leashed and are restricted from the swim beach. Camp only in reserved, designated sites. Honor shorebird-nesting closures, and check the DNR for current rules.

The resort towns of Petoskey, with its historic Gaslight District, Harbor Springs and Bay View lie close, along with Little Traverse Bay, the Tunnel of Trees scenic drive (M-119), Walloon Lake, and Lake Charlevoix. The Lake Michigan shore, the wineries and the broader Little Traverse region surround the park, making it part of one of northern Michigan’s most beloved and scenic areas.

Hunt for Petoskey stones along the shore — look for the hexagonal pattern, and wet the stones or look after a storm when they show best — while respecting collecting limits. Reserve campsites early for summer, and enjoy the calmer bay water for swimming. Pair a visit with Petoskey’s Gaslight District, the Tunnel of Trees drive and Harbor Springs for a classic northern-Michigan getaway.
