Camping sites near Alton, Illinois are situated along a corridor where the Mississippi and Illinois Rivers converge, creating diverse bottomland ecosystems. The region experiences four distinct seasons with spring wildflower blooms in April and May, while fall brings vibrant foliage from late September through early November. Winter camping options remain limited primarily to Pere Marquette State Park with temperatures typically ranging from 20-40°F December through February.
What to do
Hiking at Pere Marquette State Park: The park offers challenging trails with significant elevation changes unusual for Illinois. "Pere Marquette has many options for your stay... The hiking is worth the effort. The views from the bluffs are gorgeous," notes Shawn M., who recommends the bluff trails for panoramic river views.
Cycling on Katy Trail: Sundermeier RV Park provides direct access to this popular trail system. "You can literally be parked right at the Katy Trail. Through the gate at the rear of the campground, and you can bike for miles. Easy ride in to St. Charles a wonderful historic river town on the Missouri River," writes Cheryl K.
Paddling at St. Peters' Lakeside Park: Water activities close to urban amenities make this a popular choice. "This is a great place to kayak and camp if you don't want to drive that fare and live in the city. We love going here and watching the sunsets," says Lindsey C. about St. Peters' 370 Lakeside Park, which rents kayaks and paddleboats on-site.
Birdwatching during migration seasons: Horseshoe Lake State Park offers prime viewing opportunities during spring and fall migrations. Visitors can observe diverse waterfowl using the Mississippi Flyway. "This is a great place when the geese are migrating thru," mentions Kent B.
What campers like
Budget-friendly primitive camping: Horseshoe Lake State Park Campground offers very affordable sites with basic amenities.

Another camper noted, "Great spot in a beautiful area close to St. Louis. No power but access to drinking water and waste water dump for just 8$."
Privacy between sites: Spacious site layouts at certain campgrounds provide more solitude than others. "Very primitive camping. The campsites are spaced comfortably apart. The grounds are well maintained," reports Wendy about Horseshoe Lake State Park Campground.
Wildlife viewing opportunities: The confluence of major rivers creates habitats for diverse animal species. "We visited in the summer busy season... There are great hiking trails and the scenic drive to the park by the Mississippi and Illinois rivers is worth the trip alone," shares Michael M. about Pere Marquette State Park Campground.
Year-round availability: Pere Marquette State Park Campground operates throughout winter, unlike most area campgrounds. "The lodge has a restaurant and giant chess board!" mentions Leah H., highlighting indoor amenities during colder months.
What you should know
Noise considerations: Industrial areas and transportation corridors create sound issues at some campgrounds. "We stayed in a tent spot... It's not in the prettiest location, very industrial and the train tracks run close. First night one came through blowing its horns around 5am," writes Peter H. about St. Louis NE-Granite City KOA.
Flight paths and train traffic: Casino Queen RV Park sits beneath air traffic patterns and near railway lines. "There are trains every 15-30 minutes all day long. Casino has a metro stop that takes you into St Louis over the river," explains Josh F., though he adds, "There is train noise but we couldn't hear it with the air conditioners running."
Urban industrial settings: Some campgrounds near Granite City exist in manufacturing zones. "When you first pull down the road you'll be worried you're going to end up in the train yard, but the campground is hidden and actually really quiet and secluded," notes Jessica N. about St. Louis NE-Granite City KOA.
Reservation requirements vary: Some parks require advance planning while others offer self-registration. "Self service pay system makes it simple, easy, and fast. Camping can be reserved but no need. Just pick your spot go to the office building, and fill out the form, pay and slide in envelope and drop in box," explains Travis about Horseshoe Lake.
Tips for camping with families
Playgrounds and recreation: Cahokia RV Parque offers family-friendly facilities close to city attractions. "We had a great experience in the 4 nights we spent here. The grounds, pool, laundry, and bathrooms were all in excellent repair and clean. The park was quiet, but very family friendly," writes Lee T.
Park convenience for St. Louis attractions: Location matters when planning city excursions. "We camped here for a trip to the city for St Louis cardinals game and zoo. My kids loved the jumping pillow at the park. Minimal playground but they still enjoyed it," says Sarah S. about St. Louis NE-Granite City KOA.
Biking opportunities: Rental options make family activities accessible without bringing equipment. "The park/campground rents paddleboats, kayaks, and canoes in addition to different kinds of bikes. There is a walking trail around the lake (4+ miles)," mentions Mats about St. Peters' 370 Lakeside Park.
Meal conveniences: On-site food options simplify family camping logistics. "Do NOT miss the BBQ place in the parking lot... fantastic food and a 10% discount for park customers," recommends Lee T. about Cahokia RV Parque.
Tips from RVers
Hookup configurations: Utilities placement can require extra equipment. "Utilities are set up weird on all sites - Water and electric are at the very rear of the site by the sewer, so you will need a decent sized hose to reach if your water intake is in the front of your camper," warns Josh F. about Casino Queen RV Park.
Electrical safety concerns: Some parks have infrastructure issues. "The water pressure was so strong that I could barely open the water pump!" reports Susan L. about St. Peters' 370 Lakeside Park.
Security considerations: Gated facilities provide additional safety in urban settings. "You need a code to get in the gate, so you must register in advance... Security is proactive in patrols and are friendly and helpful," notes Greg S. about Casino Queen RV Park.
Road access challenges: Some parks require careful navigation. "A little sketchy getting off east bound ramp then having to cross three lanes of traffic to make a left hand turn at the first light. Entrance to campground is tight, swing wide," cautions James P. about St. Louis NE-Granite City KOA.
