Getting There & Parking
Understanding how to get to Pere Marquette State Park is straightforward, as it's conveniently located on Illinois Route 100, also known as the Great River Road. This scenic byway leads directly to the park entrance, approximately 18 miles west of Alton, Illinois.
For those driving from Chicago, we recommend taking I-55 South to Exit 52 at Litchfield, then IL Rt 16 West to the junction of IL Rt 100. Proceed south on Rt 100 for about 10 miles to reach the park. From St. Louis, take I-270 North to US Hwy 367 North to Alton, then turn left on IL 143, and left again at the third stop light onto IL Rt 100.
Once you arrive, you'll be pleased to know there are no entrance or parking fees at Pere Marquette State Park. The park roads are paved and generally easy to navigate, even for RVs, though many visitors prefer to unhook their RVs and explore the park in a smaller vehicle. We advise arriving early, especially on weekends or during peak seasons, to secure the best parking spots and ensure easier access to popular trailheads.
Top Things to Do
When planning your visit, you'll find a wealth of things to do at Pere Marquette State Park. Our team has highlighted some of the must-do activities that showcase the park's natural splendor and recreational opportunities:
- Hiking and Trail Exploration: Pere Marquette State Park hiking trails are extensive, offering diverse terrain for all skill levels. Pick up a trail map at the Visitor Center to navigate the approximately 12 miles of marked trails. Don't miss the Goat Cliff Trail for panoramic views of the Illinois River, or the shorter Dogwood Trail for a scenic overlook of wetlands.

It begins at Pere Marquette State Park and stretches for approximately 20.5 to 22 miles along the Illinois River to Alton, offering fantastic scenic views. Bike rentals are available at the Pere Marquette Lodge, making it accessible even if you don't bring your own.
- Eagle Watching: In January and February, Pere Marquette State Park is renowned as a prime location for observing hundreds of wintering bald eagles. The park often hosts guided tours during this period, providing an up-close look at these magnificent birds.

Best Time to Visit
Our team has found that the best time to visit Pere Marquette State Park largely depends on your interests, as each season offers a unique experience:
- Fall (September-November): This is arguably the most popular time to visit, as the park's wooded ravines and bluffs erupt in vibrant fall foliage. Scenic drives along the Great River Road are particularly breathtaking, and hiking trails offer enhanced views.
- Winter (December-February): For wildlife enthusiasts, winter is prime time for bald eagle watching. Hundreds of eagles congregate along the Mississippi and lower Illinois Rivers, making Pere Marquette a premier viewing spot. The park often hosts guided eagle tours in January and February. While some services may scale back, trails remain open, offering a quieter, frost-kissed beauty.
- Spring (March-May): Spring brings renewed life to the park, with blooming wildflowers and active wildlife. It's an excellent time for hiking and exploring the trails before the summer heat. Guided Morel Mushroom Hunts are also a popular spring event.
- Summer (June-August): Summer offers warm weather perfect for boating, fishing, and longer hikes. However, it can be busy, and mosquitoes may be present, so plan accordingly. Family-friendly events like the Two Rivers Family Fishing Fair (June 6, 2026) are highlights.
Regardless of when you choose to come, we recommend checking the weather forecast before your trip, as trails can become muddy after rain.
