What to do
Fishing opportunities: Rock Creek State Park Campground attracts anglers seeking crappie and largemouth bass. "Rock Creek is known for its crappie and large mouth bass fishing. The lake has lots of features like brush piles, vertical structures, mossy areas and you can go over by the bridge and fish the rocks," notes one visitor.
Paddling activities: The lakes provide excellent paddling conditions for various watercraft. "Very nice lake. You can rent fishing boats, pontoons, kayaks, and canoes," explains a Rock Creek camper. At Pine Lake State Park Campground, visitors can "paddle on upper or lower Pine Lake" and access multiple fishing spots.
Hiking options: Several campgrounds maintain trail systems for day hiking. "There are good hiking trails, including a walk through some wildflowers," reports a camper at Timmons Grove County Park. Pine Lake State Park features "hiking trails all around lower Pine Lake" where visitors can observe wildlife and native plants.
Disc golf course: Newton KOA offers an on-site disc golf course for campers seeking recreational activities beyond water sports. The course layout accommodates players of various skill levels and provides a land-based activity option when water conditions are unfavorable.
What campers like
Waterfront camping: Many campers appreciate lakeside sites. "We dry camped right on the water's edge for $6 a night," reports one visitor to Rock Creek. At Otter Creek Lake and Park, campers enjoy "lake front camping. Sunset over the lake!" according to a reviewer who found the setting ideal for evening relaxation.
Wildlife viewing: Several campgrounds support diverse wildlife. At Timmons Grove, "bird watchers will love this place. Also expect to see deer and turkeys," notes a camper. The relatively undeveloped shorelines around many lakes provide natural habitat for waterfowl and other species.
Clean facilities: Campers frequently mention facility maintenance. At Union Grove State Park Campground, visitors appreciate that "bathrooms and shower rooms are new and super clean. Campground is well kept," while Pine Lake receives similar praise for updated facilities where "they've recently updated the bathroom/shower houses to be shared bathroom spaces with individual shower 'closets'."
Multiple lake access: Pine Lake State Park offers the unusual feature of two connected lakes. As one visitor notes, "Fishing is good here, as are the hiking trails. Can paddle on upper or lower Pine Lake."
What you should know
Highway noise levels: Some campgrounds experience significant road noise. At Riverview Park Campground in Marshalltown, "It is right next to the highway. When I was there in a tent, the hog trucks would drive by all night (loud and smelly)." Similarly, Newton KOA sits "literally a single stone's throw from I80" where "you'll be hard pressed not to see or hear it during your entire stay."
Site spacing varies: Campground density differs across locations. At Rock Creek, "RV sites are close and busy" while "the sites both tent and RV are simply too close for you to enjoy the place." However, Wolf Creek Recreation Area offers more privacy where "the tent sites are spread out and it is fairly easy to find one without neighbors too close."
Seasonal limitations: Most campgrounds close during winter months. Union Grove operates from May 1 to September 30, while Newton KOA runs from April 1 to October 31. Some facilities like shower houses close earlier than the campgrounds themselves.
Mosquito conditions: Insect activity can impact camping comfort. As one Riverview Park camper noted, "Mosquitos are really bad here," while another campground visitor mentioned "bugs are bad this time of the year." Bringing appropriate repellent is essential during summer months.
Tips for camping with families
Playground access: Wolf Creek Rec Area provides family-friendly amenities. "The campground has a nice playground, which was a feature we enjoyed when my daughter was little," reports a regular visitor. Similarly, Riverview Park includes a "playground for the kids" among its facilities.
Swimming options: Several parks maintain designated swimming areas. At Pine Lake, campers appreciate the "beach swimming" area on lower Pine Lake, though water quality can vary seasonally. One visitor to Outback Campground noted, "Jump into the nearby water and let the kids have a blast!"
Educational opportunities: Otter Creek offers nature-based learning. "Nature Center offers education displays and programs," notes a visitor, making it suitable for families seeking educational components to their camping trip.
Budget-friendly sites: Tent camping costs range from $6-18 per night across the region. Wolf Creek Recreation Area charges "$10/night" for tent sites, while electric sites cost more at "$15/night." This price difference allows families to camp economically if willing to forgo hookups.
Tips from RVers
Electrical service variations: Kellogg RV Park provides full-service sites. "The sites are 20/30/50 amp. No water or sewer at the sites but there are water spigots dispersed through the campground and full dump station as you come in/leave," explains one RVer. At Riverview Park Campground, "Full hook up for reason price. Has electric and water sites, too."
Site leveling considerations: Some campgrounds feature uneven terrain. At Newton KOA, visitors note that "sites are level (#62)" while Union Grove has "some sites that are off with level & weird (ie stairs/door open on an incline and away from the table)."
Year-round accessibility: For winter travelers, Kellogg RV Park remains "open year around" with "nice large sites and no need to unhook," making it convenient for overnight stays during off-season travel.
Off-season availability: Many RVers prefer camping outside peak season. Rock Creek State Park becomes less crowded in autumn when "we stayed during the fall and it was practically empty." Similarly, Wolf Creek Recreation Area is "never too busy even on holiday weekends."
