Charles Mears State Park

Charles Mears State Park sits right on the Lake Michigan shore in the charming village of Pentwater, in Oceana County. Though one of the smaller state parks on the coast, it is among the most popular — a compact gem with a wide sandy beach, a campground set right at the water’s edge, and the climbable sand dune known as Old Baldy.

The park’s beachfront campsites, just steps from the warm Lake Michigan water and the village, make it a coveted summer destination that books up fast. Old Baldy, a bare sand dune at the park’s edge, offers a short climb to sweeping views of the lake, beach and town. With its sandy beach, walkable connection to Pentwater’s shops and harbor, and classic Lake Michigan sunsets, Charles Mears is a quintessential small-town beach-park experience.

The wide sandy beach is the heart of the park — swimming, sunbathing and beach play on the warm Lake Michigan shore — with the climbable Old Baldy dune offering a short hike to sweeping views. A beachfront campground puts campers steps from the water, and the park connects on foot to the village of Pentwater’s shops, dining and harbor. Compact but classic, it is made for beach days, sunsets and small-town strolling.

Summer is peak, when the warm beach, Old Baldy and the village are in full swing — the coveted beachfront campsites book up far in advance. Late spring and September offer warm sand and water with thinner crowds. Fall brings quiet beaches and dramatic surf, and winter leaves a peaceful, snowy shore. Time a visit for summer beach days and the famous Lake Michigan sunsets, and reserve campsites as early as possible.

The park is named for Charles Mears, a 19th-century lumber baron whose mills and interests shaped Pentwater and the Oceana County shore during the lumber era. The land became a state park preserving public beach access in the heart of the village, and Old Baldy and the beachfront campground made it a beloved summer destination. The park’s history is woven into that of Pentwater, the charming town it sits within.

The park’s beach and the Old Baldy dune are part of the Lake Michigan dune-and-beach system, built from glacial sand carried by waves and wind over thousands of years. Old Baldy is a bare, climbable foredune, while the wide sandy beach is the active, ever-shifting shoreline. The dunes belong to the great eastern-shore freshwater dune system, and the village harbor sits where Pentwater Lake meets Lake Michigan.

The beach, dune and nearby Pentwater Lake host gulls, terns, shorebirds and migrating birds, with the Lake Michigan shoreline a migration corridor for raptors and songbirds. The wet sand and dune grass host shorebirds, and the harbor and lake draw waterfowl. Protected Great Lakes beaches in the region can host nesting piping plovers, so honor any posted closures along the shore.

Charles Mears protects a compact stretch of Lake Michigan beach and foredune, where pioneer plants like marram grass help anchor Old Baldy and the shifting sand. Heavy summer use makes the dune vegetation vulnerable, so keeping climbers to designated areas matters. The beach is part of the active Lake Michigan shoreline, and the nearby Pentwater Lake and channel add aquatic habitat to the village setting.

Charles Mears State Park, with its beachfront campground, the climbable Old Baldy and its walkable connection to charming Pentwater, is a beloved small-town beach-park experience and a quintessential Lake Michigan summer destination. Its coveted campsites, classic sunsets and village setting have anchored generations of family summer traditions on the Oceana County shore.

Charles Mears State Park is right on the Lake Michigan shore in the village of Pentwater, Oceana County, reached via Lowell and Hancock streets off US-31/Business 31. A Michigan Recreation Passport is required. The beach, beachfront campground, Old Baldy dune and day-use areas are within the compact park, with Pentwater’s shops, dining and harbor a short walk away. Parking and campsites fill fast on summer weekends.

The DNR manages Charles Mears to protect its beach and the Old Baldy dune while supporting heavy summer use. Visitors help by climbing Old Baldy only where permitted and keeping off vegetated dune areas, honoring any shorebird-nesting closures, keeping the beach free of litter and glass, and respecting the fragile foredune grasses that hold the sand. Protecting the dune and beach preserves the park’s appeal in its compact, busy setting.

Lake Michigan’s surf and rip currents can be dangerous, and currents near the Pentwater channel and pier are especially hazardous — heed beach warnings, never swim near the pier, and supervise children. The open beach and Old Baldy are shadeless and the sand gets hot; bring water, sun protection and footwear. Watch footing climbing the dune, and keep back from the channel and pier in rough conditions.

A Recreation Passport is required. Climb Old Baldy only in designated areas and stay off vegetated dunes to protect the sand-holding grasses. Pets must be leashed and are restricted from the designated swim beach. Glass is prohibited on the beach. Camp only in reserved, designated beachfront sites — they book early. Honor shorebird-nesting closures, and never swim near the channel pier. Check the DNR for current rules.

The charming village of Pentwater, with its shops, dining, marina and Pentwater Lake, surrounds the park, and the famous Silver Lake Sand Dunes, the Little Sable Point Lighthouse, and the towns of Mears and Hart lie close. Ludington State Park and its dunes are up the coast, making the Oceana County shore a rich cluster of beaches, dunes, lighthouses and small resort towns.

Reserve the coveted beachfront campsites as early as the window opens — they go fast. Climb Old Baldy for the view, enjoy the warm beach, and walk into Pentwater for dining and shops. Stay for the Lake Michigan sunset. Never swim near the channel pier, bring sun protection for the shadeless beach, and pair a visit with the nearby Silver Lake Sand Dunes and Little Sable Point Lighthouse.
