The Ottawa area sits along the Illinois River where flat prairies meet unexpected canyons and sandstone bluffs at 482 feet above sea level. The region receives 39 inches of annual rainfall that creates seasonal waterfalls in the canyons. Summer temperatures average 85°F with high humidity requiring careful planning for tent camping in exposed sites.
What to do
Wildlife viewing at Buffalo Rock State Park: The campground's primitive sites connect directly to hiking paths with excellent wildlife spotting opportunities. "Real live Buffalo are a treat for kids and animal lovers. A number of trails around effigy mounds make for a nice walk," notes Bill M. The park serves as a quieter alternative to crowded nearby attractions.
Kayaking the Illinois River: Kayak Starved Rock Campground offers direct water access for paddlers. "If you have never sojourned to Starved Rock SP, you're in for a real treat. With more than 13 miles of trails and nearly 20 canyons to trek through, there's no shortage of absolute amazing hiking that awaits you," explains Stuart K. The campground's riverfront location provides views across to Starved Rock's cliffs.
Hiking at Matthiessen State Park: Located just beyond Starved Rock, this lesser-known park offers 5+ miles of trails through carved valleys. "We arrived at 1045am even tho check in was 3pm and no 1 was at our site... we took the dog and hiked Matthesion state park, which was beautiful and only a mile or so passed the starved rock state park entrance," shares Caitlin C. from Kayak Starved Rock Campground.
What campers like
Secluded tent sites: Buffalo Rock State Park Campground offers truly private camping experiences. "Camp sites aren't actually in buffalo rock, they're across the street at I&M canal. You have to walk a bit to get there but the sites are great. If you're looking for privacy this is it," explains Amanda P. These hike-in sites require carrying all supplies from the parking area.
Riverfront camping: Many campers appreciate the Illinois River views at waterfront sites. "Our site was wonderful and was on a point on the river that has a 180 degree view of the river. There is a picnic table and fire pit at the site," reports Paul R. about his stay at Kayak Starved Rock Campground. These sites fill quickly during summer weekends.
Shaded camping areas: Illini State Park offers wooded sites for summer heat relief. "We loved the shade of the wooded section. We had a spot that gave us enough blockage to keep our reactive dog calm," shares Art S. The park's Whitetail Campground section provides the most tree coverage for tent campers.
What you should know
Seasonal flooding concerns: Low-lying campsites near creeks and rivers can flood during heavy rain. "The bulk of the campsites are down in a valley and ours was along the creek. A heavy downpour resulted in water up over our ankles all through the site!" warns Jackie S. from Pleasant Creek Campground. Request higher ground if rain is forecast.
Water availability varies: Some campgrounds require visitors to filter their own water or carry in supplies. "No restrooms but there is a water source you can filter. Saw lots of wild life," notes Jess about Buffalo Rock State Park Campground. Always confirm water sources before arrival, especially at primitive sites.
Campsite spacing considerations: Density varies significantly between campgrounds. "The biggest thing we disliked about this place is how close the campsites are to one another. With a tent at every site, you're almost right on top of the next site, enough to clearly hear the person snoring two tents over," reports Cullen S. about Kayak Starved Rock Campground.
Tips for camping with families
Playground access: Starved Rock Family Campground offers family-friendly amenities. "Small dog area (not the best fencing though if your dog is an escape artist), pool, showers, RV amenities, amazing park for children, front office has everything you could imagine," notes Tony K. The playground provides entertainment after hiking.
Weekend activities: Some campgrounds schedule regular family programs. "They do an extremely large Halloween event Columbus Day weekend. Jam packed for this event. Awards for site decoration. Campsites set up haunted houses, candy for kids, drinks for adults. Fun to see adults and kids all dressed up," describes Lisa T. about Glenwood RV Resort.
Pet-friendly trail options: The I&M Canal Trail connects multiple pet-friendly camping areas with safe walking routes. "Walk to Ottawa is very magical," comments Jess about Buffalo Rock State Park. The flat terrain makes these trails accessible for families with varying hiking abilities and dogs of all sizes.
Tips from RVers
Electrical hookup access: Illini State Park's Great Falls Campground offers designated RV sites. "I stayed in Whitetail Campground for a few days. It was very quiet, especially during the week, and secluded. I stayed in site 63, a back-in site with electricity that is shared with another campsite," explains Inez W. Some sites require extension cords to reach electrical boxes.
Site leveling challenges: Many RV sites throughout the region require leveling equipment. "What we didn't like is the powdery gravel sites (muddy when wet) that were not very level, and the long road in is very rough," notes Bea about Glenwood RV Resort. Pack leveling blocks even for designated RV sites.
Dump station access: Plan dump station usage timing carefully during busy periods. "The dump station was also up a one way in/out hill. You had to make a tight U-turn coming down from your site to get up to it. Plan on going early otherwise you're going to get stuck on the hill waiting," advises Brian A. about Pleasant Creek Campground. Most pet-friendly camping near Ottawa, Illinois requires strategic timing for facility use during peak weekends.
