Pere Marquette State Park
Illinois’ Largest State Park at the Meeting of the Great Rivers
Pere Marquette State Park — 8,050 acres near Grafton, Illinois — is the largest state park in Illinois and one of the most scenically dramatic. Perched on limestone bluffs at the confluence of the Illinois and Mississippi Rivers, the park offers sweeping panoramic views of the river valleys below — a landscape that has drawn visitors since Father Jacques Marquette and Louis Jolliet paddled through in 1673.
The park’s centerpiece is the Pere Marquette Lodge — a magnificent 1930s Civilian Conservation Corps (CCC) rustic stone-and-timber structure featuring a legendary 700-ton stone fireplace, one of the most photographed features in the Illinois state park system. With its location on the Great River Road (Illinois Route 100) and Meeting of the Great Rivers Scenic Byway, the park is a destination for bald eagle watching, bluff-top hiking, and historic lodge stays.

Bald Eagle Watching: Illinois’ Premier Eagle Site
Pere Marquette is one of the premier bald eagle viewing destinations in the Midwest. Each winter, bald eagles migrate south from Canada and the northern states to congregate along the ice-free stretches of the Illinois and Mississippi Rivers near the park. The confluence of two major rivers creates ideal feeding conditions — open water where eagles can hunt for fish.
| Eagle Viewing Detail | Information |
|---|---|
| Season | Late December through early March |
| Peak viewing | January and February |
| Best time of day | Early morning (dawn) and late afternoon (before sunset) |
| Where to look | Treetops along bluffs, ice-free river sections, near locks and dams |
| Events | “Bald Eagle Days” — interpretive programs, video presentations, guided tours |
| Reservations | Required for Eagle Days programs — call (618) 786-3323 |
💡 Eagle Viewing Tip: Stay in your vehicle or at marked viewing areas — eagles are less disturbed by cars than by people on foot. Bring binoculars or a telephoto lens. The bluff overlooks along Route 100 between Grafton and Alton offer excellent vantage points. Dress warmly — you’ll be outside in January temperatures.
Trails & Hiking: 12 Miles of Bluff-Top Trails
Pere Marquette offers approximately 12 miles of marked hiking trails that wind through rugged limestone bluffs, forested ravines, and ridge-top overlooks with dramatic views of the river valleys below. The trails range from easy woodland walks to strenuous bluff climbs.

| Trail | Distance | Difficulty | Highlights |
|---|---|---|---|
| Goat Cliff Trail | 1.5 miles | Easy-Moderate | Leads to McAdams Peak — best panoramic views |

Sam Vadalabene Bike Trail
The Sam Vadalabene Great River Road Bike Trail — a 20-mile paved multi-use path — connects Pere Marquette State Park to Alton, Illinois. The trail runs parallel to the Great River Road and the Mississippi/Illinois Rivers, offering some of the most scenic cycling in the Midwest. The route passes towering limestone bluffs, river floodplains, and the charming town of Grafton. The trail is generally flat with a few short hills near the park entrance.
Wildlife & Nature
Pere Marquette’s 8,050 acres of forested bluffs and river bottomland support rich wildlife diversity. The confluence ecosystem — where the Illinois River meets the Mississippi — creates a mixing zone of habitats: upland oak-hickory forest on the bluffs, floodplain forest and wetlands below, and the rivers themselves.
White-tailed deer are abundant in the forest. Wild turkeys forage on the ridgetops. Pileated woodpeckers — the largest North American woodpecker at 16-19 inches — hammer at dead trees in the mature forest. Spring migration brings waves of warblers through the canopy — the bluff-top location creates a natural funnel for migrating songbirds following the rivers north. Great blue herons and belted kingfishers fish the river edges. In the bottomland, river otters have made a strong comeback after reintroduction efforts.
The Great River Road & Scenic Driving
Pere Marquette sits on Illinois Route 100 — part of the Great River Road, a National Scenic Byway that follows the Mississippi River for 3,000 miles from Minnesota to the Gulf of Mexico. The stretch of Route 100 from Alton to Grafton is considered one of the most scenic drives in Illinois, winding past towering limestone bluffs, historic river towns, and the site where the Illinois River meets the Mississippi — the Meeting of the Great Rivers viewpoint near Grafton.
History: Marquette, Jolliet, and the Meeting of Rivers
The park is named for Father Jacques Marquette, the French Jesuit missionary who — along with explorer Louis Jolliet — paddled up the Mississippi and into the Illinois River in 1673, becoming the first Europeans to explore this confluence. A large memorial cross marks their journey at the park’s entrance. The park was established in 1931 as Piasa Bluffs State Park — named for the legendary Piasa Bird, a fearsome creature depicted in Native American cliff paintings that early French explorers recorded on the bluffs along the Mississippi near Alton.
