Pere Marquette State Park
RV Guide


Sitting on over 8,000 acres of protected land where the Mississippi and Illinois Rivers meet, Pere Marquette State Park is just begging to be explored on your next RV vacation. Just nine minutes away from the city of Grafton, Illinois, the park was first established in 1931 and is the perfect escape for nature lovers and history buffs alike. In fact, many of the park's natural features help tell its history. For example, a majority of rivers and streams in the park were originally formed by the movement of large glaciers millions of years ago.

The park is also rich in cultural history and was once home to several Native American tribes. Many artifacts left behind by these ancient tribes can be found throughout the park today including pottery fragments, spearheads, and even burial mounds. The park was later explored by its namesake Pere Marquette, a French missionary who stumbled across the park after failing to find a passage to the Pacific ocean from the Mississippi River.

A lot has changed since Pere Marquette trekked through the area. Nowadays, the natural wonders of the park are accompanied by a few additions such as bike trails, horseback trails, a Visitor Center, boat launches, picnic areas, and several lodging options. However, the important parts of the park have stayed the same, like the abundance of fish, the natural rock formations that create fun rock climbing areas, and the many species of birds that can be spotted flitting around the park. Regardless of when RV visitors come to Pere Marquette State Park, there is plenty to enjoy.

RV Rentals in Pere Marquette State Park



Pere Marquette State Park is a breeze to find since it is located right along the popular Illinois Route 100, also known as the Great River Road. The scenic byway takes visitors around the perimeter of part of the park and right to the entrance. The interior roads are paved and lack any sharp turns, so it's pretty easy to get around the park using any mode of transportation. The park roads are in good condition so guests will not have to worry about any narrow bridges or very steep inclines. Though not impossible to navigate the park via RV, many guests have found it much easier to hook up their RV and navigate the park in a car instead.

Be aware that the roads don't show off everything in the park. The hiking and biking trails are really what take guests through the park and let them get up close with nature. This is why many visitors also choose to bring bikes or scooters for exploring the park trails. The bike trail within the park is paved, so it's suitable for all members of the family and continues all the way to the city of Alton, almost 20 miles south of the park.

Seasonal activities in Pere Marquette State Park



Fishing along the Illinois and Mississippi Rivers is a popular recreational activity at Pere Marquette State Park. With boat launches readily available in the park, it's easy to get out and find a secluded spot to fish. Anglers can expect to catch a wide variety of fish from the diverse river ecosystem, including white bass, largemouth bass, catfish, drum, carp, bluegill, and more. The Two Rivers Family Fishing Fair is held annually in the park and is a great opportunity to fish as a family. For visitors who do not own their own boat, rentals are available.

Rock Climbing

Adrenaline junkies will love Pere Marquette State Park's rock climbing. While the limestone formations may not be suitable for beginners, experienced climbers and repellers will have a ball. Adventurous climbers can pack their trad racks for any of the dozens of trad climbs in the park, and sport climbers can send any of the dozens of bolted routes. The routes in the park range from 5.7 (easy) to 5.11 (difficult), so there's something for every level of climber.


With nearly a dozen miles of trails meandering through the park, there is plenty of opportunities for beginners and experts to explore the park while taking in breathtaking views of the surrounding natural beauty. There are nine scenic overlooks in total, spread out along the trails. The trails are easy to follow and are marked for hikers' convenience. If traveling with small children, the Ravine Trail is a great option at only a half-mile long. Visitors who are seeking a longer, more challenging hike will want to try the 2.5-mile Fern Hollow Trail.


Horseback Riding

Horseback riding is another activity that can be enjoyed year-round at Pere Marquette State Park. The park features over 20 miles of bridle trails that offer an excellent way to explore the 8,000-acre park. Some of these trails are seasonal and are not open during the whole year. Guests should be aware that during the off-season the Pere Marquette Stables is closed, so visitors will have to bring their own horse if they plan on exploring on horseback.


A favorite for bird lovers year-round, Pere Marquette State Park is home to over 200 species of birds. Although visitors won't be able to see all of the birds that call the park home, they can spot some of the most popular birds during the winter months. Bald eagles are known to perch in the trees and fly high above the park during the wintertime, and seeing one is a once in a lifetime experience for many people.

Exploring the Visitor Center

The Visitor Center is open year-round and features a 3D map of the park. The exhibits within the Visitor Center teach visitors about the natural, cultural, and geologic history of the park. These engaging exhibits also educate visitors about the wildlife in and along the Illinois River.
