The park contains limestone cliffs that form part of the Niagara Escarpment, a geological formation extending through the Great Lakes region. Winter temperatures near Combined Locks typically drop to the low teens in January, while summer camping season brings temperatures averaging in the mid-70s with moderate humidity levels from June through August.
What to do
Hiking seasonal trails: Several campgrounds near Combined Locks offer hiking opportunities with varying difficulty levels. Mauthe Lake Campground offers trails for all seasons, with one reviewer noting, "Lime kiln trail is difficult but so worth it." Many trails connect to the Ice Age Trail system, where a camper mentioned, "Some trails on the Ridgeline offer vista views and moderate inclines that add to the adventure."
Water recreation: Lake Winnebago provides multiple access points for fishing, kayaking and canoeing. At Calumet County Park, a reviewer highlighted, "Located along the shores of Lake Winnebago the views are beautiful. There is no beach for swimming but plenty of areas for fishing. The park also has a marina/boat launch." Water quality typically remains good through early summer.
Wildlife observation: Natural habitats around Combined Locks support diverse wildlife populations. At Hickory Oaks Campground, campers reported, "We saw so much wildlife! Chipmunks, ducks, a great horned owl, and countless birds to name a few." Morning and evening hours provide optimal wildlife viewing opportunities at most area campgrounds.
What campers like
Spacious campsites: Many campgrounds near Combined Locks feature well-separated sites. One camper at Calumet County Park shared, "Excellent county campground with some of the largest sites we've come across. Things we look for in a campground: space from neighbors, shade, and quiet. This park checked all the boxes!" Sites with electric hookups typically range from 30-50 feet in length.
Clean facilities: Well-maintained bathrooms and shower buildings consistently receive positive mentions. A camper at Devils River Campground stated, "The bathrooms/showers were very clean and well kept. They also had laundry services!" Most campgrounds in the area maintain regularly cleaned facilities with scheduled maintenance days.
Quiet atmosphere: The peaceful setting appeals to many visitors seeking relaxation. At Mauthe Lake Campground, a camper noted, "The sites are well separated for privacy." Another mentioned, "Campground facilities are clean, 30 amp at the electrical site worked perfectly. Other campers amazingly friendly."
What you should know
Seasonal considerations: Area campgrounds typically operate from April through October with limited winter access. At Devils River Campground, a reviewer advised, "The New Hope Cave is only open to tour 1 weekend of the month. It is usually the 3rd Saturday of the month but there were scheduling conflicts." Water systems at most campgrounds shut down after mid-October.
Insect preparation: Summer months bring mosquitoes and flies to wooded camping areas. One camper at Devils River Campground warned, "The only negative with our stay (which the campground can't help) were the mosquitos, flies, and bees. So bring bug spray!!!" Peak insect activity occurs from June through August, particularly near water features.
Reservation requirements: Most campgrounds require advance booking, especially during summer weekends. A camper noted, "They don't have a ton of sites and they are reserve only. The weekdays are extremely quiet but the weekends get a little busy due to the seasonal sites." Reservations typically open 11 months in advance for state parks and 6 months ahead for county facilities.
Tips for camping with families
Swimming options: Several campgrounds offer designated swimming areas for children. At High Cliff State Park, a visitor commented, "Really cool cliffs to climb/hike. There is also a lime kiln to hike to and see. There are two playgrounds for the kids as well." Swimming beaches typically open from Memorial Day through Labor Day.
Recreational programs: Some campgrounds schedule family-oriented activities during summer months. At Fremont RV Campground, a camper shared, "My family really enjoyed the 'Hey Ride.' Will be returning!!" Another noted, "Great waterfront camping. Great outdoor waterpark. Fun dance for kids on Saturday night."
Fishing accessibility: Easy fishing access makes for enjoyable family outings. A visitor at Hickory Oaks mentioned, "Well stocked pond, easy to catch bluegill." Most fishing ponds don't require licenses for children under 16, though adult supervision remains necessary for younger children.
Tips from RVers
Site selection: Choose appropriate sites based on rig size and hookup needs. At Osh Vegas Palms, a reviewer noted, "Grass Sites with easy entry for our 42 ft motor home without disconnecting our tow vehicle. 50 amp, water. And this small campground has great WiFi!" Most campgrounds provide site dimensions on their reservation systems.
Utility considerations: Check campground listings for available electrical amperage and water connections. A camper at High Cliff State Park mentioned, "Great spot, lots of trails, and the bathrooms were clean. Only gripe is the uncertain schedule they have for turning on water for the season. First week or two of may is a safe bet, but no promises." Dumping stations typically remain open throughout the camping season.
Access logistics: Navigate campground roads carefully, especially with larger rigs. One camper advised, "We have a 30 foot camper and the site we were on, let's just say we had a hell of a time backing up and smashed one of our back windows in the truck that's how tight it was." Most campgrounds provide turn-around areas for larger vehicles at campground entrances.
