What to do
Hiking trails: Seven Lakes State Park offers extensive hiking paths around multiple lakes. "Seven Lakes has a great hike that takes you all around the lake, as well as smaller loops. You can find challenging hikes or an easy path. Sunrise is stunning here. Do make sure you bring plenty of bug netting/spray/gear if you come in the summer, the bugs are brutal," notes Maggie M. from Seven Lakes State Park Campground.
Swimming beaches: Camp Dearborn features multiple swimming areas for families. "Lots of beach area and water to fish or swim. Activities almost every night. Paddle boats, mini golf, golf, and more. Pull behind sites were easy to access. Staff are very helpful and responsive," writes Ryan S. who camped at the park in July 2025.
Fishing opportunities: Multiple lakes throughout Holly Recreation Area provide good fishing spots. "We love this place and so do my 3 dogs. We got a secluded campsite, and it's gorgeous- tucked into the woods and was easy to back into. You're far enough from people to where you don't really see a lot of them or hear them that often besides people walking by," says Ashley F. about Holly State Recreation Area.
What campers like

Family activities: Groveland Oaks County Park offers numerous amenities for children. "We joined a group site and meet up every major holiday at Groveland. We feel like we went up North without the driving four hours. The park is well laid out and includes a ton of fun activities for young and old," writes Mike N.
What you should know
Weather considerations: Holly area campgrounds can experience significant rainfall. At Detroit/Ann Arbor KOA, "After only a few hours of moderate rainfall, we arrived to a completely flooded park... it was completely underwater. When we told him the obvious, he said, 'they all are'," recalls Kara W.
Site selection: Carefully review campground maps when booking. "Some camp sites are squished up to others. Other camp sites have plenty of room. So when you are stuck in a spot that is tight it kind of ruins the experience. Weird thing is, the bigger sites are the same price," advises Kristin T. about Pine Ridge RV Campground.
Seasonal availability: Most rv campgrounds in Holly, Michigan operate seasonally. Haas Lake Park's season runs "Mar 29 - Nov 5," while Pine Ridge RV Campground operates from "May 1 - Oct 31." Always call ahead to verify current operating dates.

Tips from RVers
Site leveling concerns: Many Holly, Michigan RV campgrounds require leveling equipment. "Very pretty pull through sites, some are tight, but none are impossible. Knowledgeable and friendly staff. There's private land on either side and a dirt bike track that the neighbor owns on the north end, so if you've got a light afternoon napper, stay away from that end," suggests Mitchell C. about Pine Ridge RV Campground.
Water and electrical hookups: Camp Dearborn offers full-service RV sites. "Pull behind sites were easy to access. Staff are very helpful and responsive. There is a dump station on site," notes Ryan S., highlighting important amenities for RV campers.
Campsite spacing: Some rv campgrounds near Holly provide more space between sites than others. "Large sites big campground. Rained the whole weekend so couldn't enjoy it like we wanted to. Will go back," shares Dan H. about Haas Lake Park RV Campground, indicating the spacious nature of the sites despite weather challenges.
