    Located 10 miles northeast of Rockford, Rock Cut State Park is a 3,100-acre recreation area that encompasses two natural grasslands, a natural creek area, a nature preserve and 162-acre Pierce Lake. The area was designated a state park in 1957 as a way of preserving a local polititian’s favorite fishing hole. Prior to this, the park and wider area has a long history of Native American residence, including the Mascouten, the Winnegabo, and the Chippewa. With abundant water and preserved natural areas, the park now supports a thriving habitat for local birds, fish and wildlife. And with year-round camping and outdoor activities, you can experience the many seasonal sides the park has to offer. The campground at Rock Cut provides 270 sites that can accommodate tent campers, as well as RV and trailer campers up to 40 feet. Back-in sites are mostly grassy and equipped with picnic tables, cooking grills and electrical hookups. The campground provides water faucets, restrooms, showers, and a dump station; the water and dump station are not available November through April. One of the park’s multiuse trails runs right through the campground, and provides access to the larger trail network. Most of the campground’s facilities are ADA accessible. Dogs are permitted in the park, but must remain leashed; alcohol is not permitted. For recreating in temperate seasons, more than 40 miles of hiking, cycling and equestrian trails allow you to explore the park’s woodlands and prairies. These are ideal ways to observe some of the local birds, animals, and wildflowers. For fun on the water, paddle around in a canoe or kayak, take a dip at Olsen Beach, or go fishing for some of the lake’s largemouth bass, bluegill, sunfish, pike and walleye. Several picnic areas throughout the park are ideal for group or family gatherings. In the snowy season, many of the park’s trails are open to cross-country skiing and snowshoeing, with gear rentals available. For more family fun in the area, check out the nearby Volcano Falls Adventure Park.

    cant wait to go back

    I ended up here because I was going to a music festival in the area, and they turned me away because I have a service animal. I wasn't going to do all that work for nothing and just go home, so I decided to look up my nearest campground and it was KOA in Milton. they made me feel welcome. they understood my dilemma. it was a wonderful weekend. lots of amenities and I just absolutely can't wait to go back next year. I'm going to try to make it a couple times. so much fun, just me and my dog. And one last the thing, my fellow campers were more than hospitable and very nice and I appreciate that very much.

    Great little campground

    We booked a weekend here for a soccer tournament we had in Verona, so we didn’t spend a lot of time on the property. The staff was amazing! Very friendly and helpful for us new to camping people. We booked online and they were also friendly when I messed up my reservation so thanks for that too. We booked in VIP 1, which is right next to the bath house. We wanted to be close to the showers (coin op). We figured since we’re at a sporting event that might be nice. Very quiet at night. We did have a little time to go fishing at the fishing pond. We didn’t catch anything but we had fun. The fishing pond is a ways from our camping area though. It would have been a long walk so we drove. WiFi is for a fee but it was fine. The fee wasn’t expensive (less than $5). No sewer hook up but there is a dump site so no big deal. Overall good stay.

    Wonderful Little Campground

    We stayed at this campground over Labor Day. The owner intentionally doesn't fill all of the sites in order to give people more space- a great luxury over a holiday like this. The sites are pretty small and only one 'sleeping structure' is allowed on each site but we found that Jeff was very willing to let us put up two tents (one for my wife & I 

    + one for the kids) because we were in the same family.

    The bathrooms and showers were very neat and well maintained. We didn't use the showers because they were paid but our friends did and had good things to say about them.

    The campground has a very nice playground (the favorite of the trip for one of my kids) and a lounge where anyone staying at the campground can rest with A/C, wifi, a phone charging area, and some board games.

    The primary drawback is that there isn't a lot of outdoor activities to do in the area. All the land is private so there's not great hiking (a little in the state park about 20 min drive away), IL law allows waterways to be privately owned so you can't kayak the river, etc. Galena is nearby if you want to go shopping and we really enjoyed going to Terrapin Apple Orchard and picking some apples (if you're there in the Fall). But all in all I would say this is a great campground to rest and relax at- probably not ideal for outdoor adventures.

    Quiet Spot

    Pulled into the loop, and the host greeted us immediately. Confirmed our spot and backed in. Level spot with a fire ring and metal picnic table. Our spot was back by the road but was still nice. They have very clean bathrooms with showers. Volleyball net, swings, and spots for boats. Would definitely stay again and enjoy the lake a bit more.

    Great for families

    Lots of playgrounds for kids age 2-10. Pit toilets smell- I’d avoid sites around them. Hot Showers by lot 30 and at pool. Pool is not heated as stated- definitely not 80 degrees. West tower is the best for sunsets. Site 75 was nice as it was a bit back from the road and you can’t see your neighbors.

    Nice spot for summer camping.

    I've visited this campground twice and it's been a hit both times.

    Pros:

    - Scenic overlook is gorgeous.

    - The dense tree cover and near-constant slight breeze help to both keep this campground cool and the mosquitos at bay.

    - Well-kept vault toilets.

    - Close to a many points of interest.

    Cons:

    - Some of the sites are strangely graded and situated.  One site near ours had the fire pit at the very edge, making sitting around it virtually impossible.  14 was a pretty site but had a large tree in the middle of it.

    - Using the County website to reserve the site was clunky and time consuming.

    Tower Hill State Park

    Cool spot, underwhelming experience.

    I have stayed at this campground three times in the last decade or so.

    Pros:

    - Excellent location if you're looking to recreate on the Wisconsin River or visit the American Players Theater across the way.  

    - Interesting history about the Shot Tower on site.

    - Nice little hiking trails.

    Cons:

    - Every time I've visited we've dealt with lots of mosquitos, but nothing comes close to our most recent visit!  It was a mosquito massacre.  So terrible that after coating ourselves in DEET and eating dinner there the first night, we actually booked another campsite about a half hour away (Brigham County Park - a gem!) and abandoned this site altogether.  

    - Vault toilets were fragrant.

    Great, friendly, affordable, convenient

    We needed a place after visiting the House on the Rock and couldn't find anything with hookups nearby. We stumbled upon Tom's Campground hoping to find a site. We pulled in and Tom met us at our camper as soon as we got to the top of the hill and before we even got out. He was very friendly and informative. Showers were good enough but we aren't picky, 7 minutes for $0.25. The area was beautiful.

    Yellowstone Lake State Park

    Def do not recommend for summer 2024!

    I wanted so badly to love this campground experience, but just didn't. Site 19 was an easy walk-in that theoretically had nearby vault toilets, parking, and water.

    Each site only had space for one car to park before walking in. Not a huge deal, but annoying as there were 2 of us who drove separate and we had to problem solve. When we got to the site I was shocked to see that what was labeled as a tent site had literally NO flat space to actually set up a tent. Spacious site, but fully sloped.

    Also, what I would have loved to know, is that the vault toilets are closed because they are doing construction to build something new in that space. Construction that starts loudly each day at 7am. Honestly every site from about #35 down was affected by the noise because the construction is happening in the middle of the loop (and actually blocking some of the one-way road as well).

    The park in general was okay. Per the usual, the pet areas were lacking. No beach at all, just grass covered in goose poop and one cut out on the raised shore between tall grasses and foliage where a dog could potentially jump in. Certainly nowhere for a human to enjoy the water with their pups unfortunately.

    Ok but you have to work around the events going on because you have to leave when they are going on!

    Nice quiet place no neighbors usually bothering you showers and toilets could be better but overall ok

    Madison Campground

    Cute campground - near Madison

    We were in Site# B1. We had Full hook- up with a gravel pull-thru. We travel towing a 14 foot trailer and were able to fit both in our pull through site. My jeep though did not fit. The site was easy to level.

    Our site was shaded with lots of trees. This was a larger sized lot with our neighbors not too close (but we did choose a premium site with a patio and paid extra to be on the end).

    This specific lot comes with a concrete patio The lot comes with a picnic table and fire hole in the ground.

    They have a community Outdoor kitchen-y area with picnic tables.
    They do not provide garbage service at your site so you must walk to garbage dumpster.

    You are allowed to ride personal golf carts. There is really not a need to have a Golf cart because it is a smaller campground.

    They do have a Swimming pool.
    There is a Playground. They also offer horseshoes and a volleyball court.

    They have a great general store.

    The streets are gravel so not great for riding bikes but there are great places to ride bikes outside of campground, especially around Middleton and Madison.

    They have cabins for rent and tent areas.

    They have one shower house. The shower house has the typical stalls. These are kept mostly clean.

    There is a laundry facility. It is a cash only facility, but they have a change machine.

    They have a fenced in dog park and many grassy areas to walk dogs.

    There were no trails to hike in the campground.

    Some fun things to do outside of the campground are the Saturday Farmer’s Market in Madison and multitude of bike trails.

    Rock Cut state park

    Not well maintained

    We have a 30 amp trailer. When we got there, the electricity wasn't working. It was 93° on a Saturday. We called the Rangers and asked them to look at our site breaker since it kept tripping. They came, told us the park was old and not updated but then ultimately told us it was our trailer. We had to rent a motel for the night because we couldn't even pull out the slide or anything. This was after spending about 6 hours pulling apart all the electrical in the trailer. Went to camping world the next day just for us to use their plugs and it was fine. We thought maybe it was our cord so we bought a new one and still nothing. We called the Rangers again who came to look at it. Told us that the park was just so old that it probably couldn't keep up and moved us to a 50 amp sight. The 30 amp plug there would work for about 2 mins and then would keep tripping again. So we ended up having to go back to camping world to get an adapter to use the 50 amp. Wasted about 30 hours of our trip over their electrical not being updated and they knew that. Tried to reach out to get the first night reimbursed since we literally couldn't even stay there or use our trailer. Was told we had to come back the next day to speak to the head ranger, came back and he wasn't there again. Was told he would call us two different times and never got a call. Will never stay here again.

    Basic

    While the location is great for fast travels into Madison, or getting to great hiking areas. My only complaint is that not every pull through is provided with a fire ring to burn wood (they almost seem random) and that the check in building is a bit bare. Otherwise, great location, great (partial) amenities, and good customer service.

    Okay if other campgrounds are full or for just 1 night

    Easy to get to from I-90 but also a bit too close so there is road noise. The price may be a little high at $66.00 per night but the sites are all drive through and can handle large rigs. Not bad for a quick one-night stay. Many available sites even on memorial weekend 2024

    Crazy Horse Campground

    Used to be a great place to camp

    Unfortunately, I can no longer say this is a great, affordable place to stay. The weekly rates increased by over $75 a week for the full hookup sites this season.  

    There was also a link to last years pricing still active until 4/16 that has since been deactivated when I asked to have my pricing adjusted to that amount. Seems deceptive to me, having 2 different prices in 2 different places on their site.  They will not honor the price and told me if I don't like it I can find somewhere else to camp. 

    Also, they no longer offer kayaks, which was the big draw to the campground. 

    We may keep our reservation this year, but likely won't be back next season.

    Canoe paddle and sandbar camping

    Paddle trip in early June 2023. From Prairie du Sac to Spring Green, about 21 miles? Went mid week, saw one Boy Scout troop but generally nobody else.

    Campsite was beautiful with a fire pit and some left over wood from the previous group. BUT, even though you couldn’t see the road you could hear it. It’s a truck route so at 6:30am it was busy with trucks and noisy which definitely took away from the vibe of dispersed camping.

    Water levels were good. Weather was beautiful.

    Only camped one night. We rented the canoe and they ran the shuttle for us, which was very easy to arrange. Would do this again!
