The central Illinois region surrounding Princeton features predominantly prairie terrain punctuated by river valleys, with elevations ranging from 450-700 feet above sea level. Camping options cluster along the historic Hennepin Canal system with its 80-mile waterway linking the Illinois and Mississippi Rivers. Summer temperatures typically range from 60-85°F with higher humidity, while spring and fall offer milder conditions with occasional rain.
What to do
Hiking along canal paths: At Hennepin Canal Lock 21 Campground, visitors can access the 80-mile trail system directly from camp. "No reservations. We only saw two other campers, so lots of spaces. Pit toilets along the canal. Well kept. Small gravel bike trail along most of the canal. Nice place to kayak and canoe," notes Jeff and Linda L.
Fishing opportunities: The canal system and nearby lakes offer multiple fishing spots within walking distance of campsites. "There's lots to do at this park—they rent kayaks, paddleboats, and basic fishing boats. There's some good fishing, if that's your thing," writes Stacie H. about Chief Keokuk Campground.
Off-leash exercise: Hickory Grove Campground provides a designated dog park where pets can run freely. "Sites give you TONS of room and they are all FHU," notes Dan M. The campground connects directly to the Hennepin Canal bike trail, offering additional exercise options for pets and owners.
What campers like
Spacious sites: Condits Ranch offers particularly large campsites appreciated by those traveling with animals. "Condit's Ranch is family friendly and away from it all. Sue and the staff could not be nicer. We did tent camping and the setup was perfect. Huge lot. Fire pit and electric," reports Mike P.
Quiet atmosphere: Despite its popularity, many campgrounds maintain peaceful environments. "It was booked solid but you can not tell. Very quiet and peaceful campground," shares Ryan B. about Chief Keokuk Campground, making it ideal for pets who may be sensitive to noise.
Shaded pine forest: The tall pine trees at Chief Keokuk Campground create a distinctive camping environment. "A lovely campground. It's nestled in a pine forest so if you love hammock camping, this place is perfect. The sites are spread out enough that you don't feel like you are on top of other campers," explains Stacie H.
What you should know
Primitive canal camping: The Hennepin Canal Lock campgrounds offer basic facilities only. "This small campground has separate space for equestrian campers and those without horses. There are picnic tables, vault toilets and water. The campsites are all on grassy areas with trees at the edges," explains Art S. about Lock 21.
Leash requirements: Most campgrounds enforce strict leash policies. At Hennepin Canal Lock 11, "The camp sites here are right between the parking lot and the fishing spots so all the fishermen and hikers go right through your site," notes Holly J., making proper leash control especially important.
Water conditions: Water access points vary in quality throughout the season. "The primitive nature of canal campgrounds means pet owners should pack sufficient water, as potable sources are limited," according to camping guidelines. Jeff F. confirms: "Water was available on my visit 10-7 thru 10-10. The place is clean and well kept, including the pit toilets."
Tips for camping with families
Seasonal activities: Green River Oaks Camping Resort organizes themed weekends for families with pets. "The staff at Green River Oaks Resort really put a lot of thought and love into the campground. Everything is very family friendly. They have a wonderful activity director that loves children, and the children adore her," shares Nicole K.
Pool facilities: Multiple campgrounds offer swimming options during summer months. "Place was clean, they have a nice little store filled with goodies, kids enjoyed the pools and other activities they had going for the weekend," mentions Jeremy L. about Green River Oaks.
Site selection: Choose sites strategically based on pet needs. "Our campsite, 85, had nice shade and lots of trees. You can see and hear your neighbors but there is decent separation. We had space to hang a hammock and have a fire, with a full picnic table as well," describes Kim L. about Starved Rock Campground.
Tips from RVers
Hookup considerations: Pleasant Creek Campground offers various site types for different RV needs. "The sites up on the hill are nicely spaced out and deep. We will definitely be back. The only issue we had was the narrow road up the hill, I would hate to be half way up and meet another camper coming down," cautions Rodney D.
Seasonal limitations: Many campgrounds operate seasonally, affecting water and electrical services. "One of our favorite places to camp, kayak, and fish. The only downside is no water/sewage hookup," notes Jeremy K. about Chief Keokuk Campground.
Site drainage: Heavy rains can affect low-lying camping areas. "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. about Pleasant Creek Campground, important information for RVers with pets.
