What campers like
Challenging dune hikes: At Indiana Dunes State Park Campground, visitors appreciate the Three Dune Challenge hiking trail. "The 3 dune challenge is not really a challenge if you are moderately healthy but it is fun and scenic! The cool soft sand feels fantastic, definitely best hiked barefoot," suggests Greg S., who enjoyed this distinctive terrain feature.
Dog exercise areas: Dog owners appreciate the designated exercise spaces at various dog friendly campgrounds near Thornton. "We have a nice big field for the dog to run. Nature trails and of course Cedar Lake. People seemed friendly," reports Christopher G. about his experience at Cedar Lake Ministries RV Park.
Clean shower facilities: Campers frequently mention the condition of bathroom facilities, with Blackwell Family Campground receiving positive notes. "The bathhouse is newer and kept fairly clean. I don't think they're checked everyday though because the ladies stalls were out of toilet paper our second morning," shares Lisa S., noting the maintenance routine could be more frequent.
What you should know
Highway noise levels: Several pet-friendly campgrounds near the Thornton area are located near major highways, which impacts noise levels. "You can throw a stone and hit a semi driving by to I-80. There's a lot of traffic given the proximity to Chicago. If you're able to sleep with large trucks driving in the background, you'll be fine," warns Iris A. about Martin's Camping Ground.
Seasonal water potability: Water systems may not operate year-round at some locations. "The water is not yet potable so bring your own or check with the park team to ensure it's drinkable when you go," advises Hatie P. from her early spring visit to Camp Bullfrog Lake.
Train noise disruptions: Several campgrounds experience regular train noise throughout the night. "The only reason I rate this park a three is that it's very close to train lines and the trains going through and blasting their horns all night long. If you're a heavy sleeper and can deal with that, you'll be just fine," cautions Kaley A. about her experience tent camping at Indiana Dunes State Park.
Tips for camping with families
Best sites for privacy: At Dunewood Campground, families can find more secluded options among the wooded sites. "The sites are decently private with good tent pads. Shower house was clean with good hot water. A camper sink for dishwashing was a nice bonus," reports Katherine T., highlighting amenities particularly valuable for family camping.
Free firewood benefits: Some campgrounds include firewood with your stay, saving families additional expenses. "Each site comes with a free bundle of oak firewood which is nice to use on the fire pits," mentions Josh M. about Camp Bullfrog Lake, though other campers noted quality issues with the wood sometimes being wet or hard to burn.
Gate closure timing: Families should note that park gates may close earlier than expected. "If you are staying here to see Chicago the gates close for the park an hour after sunset," warns Rich M. about Blackwell Family Campground, an important consideration for families planning evening activities off-site.
Tips from RVers
Site layout considerations: RV campers should research site layouts before booking. "Sites # 4 and 5 probably have the longest length parking pad," shares Tim K. about Camp Bullfrog Lake, adding "There is NO shade during the day. None at all due to the trees within the campground being small."
Limited hookup availability: Not all campgrounds provide full hookups. "No water hooks up. Water on site but, not ideal. Really nice views," reports Kaitlin M. about Camp Bullfrog Lake, suggesting that RVers arrive with full water tanks and empty waste tanks.
Leveling challenges: Several campgrounds have uneven sites requiring additional setup time. "Spaces are small, muddy, and un level," notes Beth B. about Martin's Camping Ground, adding that "Sewer connection at our site was technically on neighbors…we had to use extension."
