Whether you're looking for family fun or peace and quiet, you'll find it at Milton KOA! Nestled in the rolling hills and valleys of Southern Wisconsin's countryside, Milton KOA is isolated from today's frantic pace-yet, it's only minutes from the Wisconsin-Illinois border. We are very proud of the resort we have built.

In just 26 years it has gone from an empty field to one of the highest rated campgrounds in the county. Whether it is the immaculately landscaped grounds or the clean and modern facilities, we are so sure you will enjoy your stay with us that we guarantee it. So if you are vacationing with us for a week or two or just passing through for a night, your stay with us will be one of the highlights of your trip.
Services
Our clean, modern facilities are what set us apart from other campgrounds. The 7,500 square-foot clubhouse has three levels of amenities and entertainment for your pleasure, including video games, TVs, meeting rooms, free showers and restrooms, and a full store for your convenience!

For whatever you need to make your camping vacation awesome, our huge on-site store is filled to the brim so that you don't have to venture outside the campground to keep the KOA fun going!The Snack Attack Shack at Milton KOA is serving up a delicious menu of burgers, pizzas, ice cream, and more. Our restrooms and showers at Milton KOA are immaculately clean, convenient, and easily accessible from wherever you're staying at the campground.

Every year we bring some of our grandchildren with us. We enjoy this park and there are a lot of things for the kids to do. The grounds are clean, the facilities are clean and we like the fact that it's family-owned! Keep up the good work and we will see you next year! Too many campgrounds claim they are a resort but you realize this place is different as you turn onto their landscaped long drive back into the resort.
There's always a party going on poolside at Milton KOA! Chairs, tables, conversation, and sunshine. The pool is the gathering place for splashing the day away with friends and making new acquaintances. Jump in and make waves or enjoy a dip near the waterfall. Without question a staple of a camping vacation, horseshoes is an outdoor favorite that is always the scene of fun, competition, and great memories made in the outdoors!

Overall very clean and well kept. Nice bathrooms. Our first time staying at a KOA. It is a little more congested than the state parks we usually stay at, but a group of us had 6 sites all backing up to 1 community fire ring and we had a blast. The trick or treat camping was awesome most people had a station for kids and another for adults. The costume contest and the haunted barn were a good time too. Hoping we can find a weekend that works for trick or treat camping next year.

Always have a good time there. Well maintained campground. Lots of activities for the kids and adults. The kids were disappointed that they couldn't pre-order donuts on Saturday night for Sunday morning.

Staff is super friendly and helpful. Emaculate bathrooms and clubhouse. Vary nice pool. Water electric and sewer hook-ups available at a large portion of the camp sites. Food delivery from the snack shack is fast and delicious. Twice daily garbage pick up. Plenty of activities for the whole family. This is one of the best campsites I have ever seen. Only complaint is that we weren't staying longer.

My family & I love this campground. We visit several times during the season. The campers and campground staff are always so friendly and they have an amazing pool. Their snack shop and store is equally amazing. Thank you again!

This campground is now a KOA Holiday. Grounds upkeep is unbeatable. We had rain that washed away some of the gravel on the road and maintenance was out the next day taking care of it all. Garbage pickup is conveniently picked up at your site each day. They have a well stocked camp store that also serve a good selection of food you can call on your order and they will deliver it to you at the site. You can also order firewood to be delivered. Restrooms cleanliness is exceptional. Staff is very professional. We are full-time right now and we stayed for a couple of months. All in all it was a great

This KOA is beautiful!! Well groomed, manicured lawns, very clean updated bathrooms and showers. Well organized camp spots. Convenient hook-ups with dumping drain for sewage. Very nice pool with unique shape. Jacuzzi for the grown-ups. Well tended flower beds throughout. Nicest KOA we've ever been to. Highly recommend!

This was our Labor Day disaster! Heavy rains I can understand, a little mud is ok, but this was insane!
We could not even step foot out of our RV without sinking in ankel deep water.
This rv "resort" is way to expensive. We have been camping here for 15+ years with 7 other families and have not seen any "improvements" that would justify the outrageous cost increases. Staff is extremely difficult to work with and the customer service is non-existent. Time for a new place!
