We had a wonderful time my grand kids went fishing for the first time.The cabin that I stayed in did not have a coffee maker in it, Carl went and got a new one, not that is service,thanks can't wait for our next camping adventure in July.☺

It was wonderful. We have been before and we will retune again. It is clean and quite. We will be back because both of our boys are attending UNI. Better then a hotel in my opinion. Thank you

Very friendly and welcoming. This is a very large campground and was very well maintained. Great activities for a family.

nice location but the showers were too hot and the area around the fire pits was very unlevel, hard to sit around.

Everything was great!

The only reason I didn't give 5 stars is because the wifi did not work really great.

This is our favorite KOA, we recommended to friends in Biloxi, MS and they stayed on the way back to Minnesota and loved it!! Great group of people working at this park!

First off, the KOA was beautiful, my wife and I enjoyed our stay. Our only problem was when we made our reservation they didn't tell us that the showers weren't available. They did offer a cabin to shower in but it didn't have hot water. I hope the park works out these d4tails.

Our last night on the road this winter was great. This KOA staff went out of their way to make our stay great.

This is the best campground ever. We were there in the winter and I can't wait to go in the warmer weather. The camping cabins are so cute and they are situated around the lake/pond. The small beach area is great also.

Wonderful to have a campground for a one night stay when traveling through-and open all year! Great! We will definitely stop again, nice level spots and full service campground.

a beautiful park rather unique

Excellent facilities would be wonderful in summer Unfortunately the bathrooms with showers were closed while we were there. I think that the website should indicate that all facilities are not available in winter months. Staff was friendly and extremely helpful
Nov 12, 2014
Clean and very close to many shops, restaurants, a small lake, a casino and a water park. We will return in the summer!

Stay was great. They were very awesome to work with. We recommend to anyone who has a student at UNI and needs a place to camp.

Unfortunately I arrived during the off-season. I can see this place being a lot of fun during the height of summer. Very handy having a petrol station as part of the site.

Nice park, poor maintenance. Garbage at playground, no bags at dog park.

Loved the campground and the staff was super friendly and accommodating.
Oct 21, 2014
The staff is so friendly! I wish the cabins had more dishes etc. but I other than that, I love the cabins and having everything right there at the store too! With all the hustle and bustle in my life, it is so peaceful to stay right by the water.

This was our second stay at the Waterloo KOA. We love the location to visit family, and like that the grounds are dog friendly with a nice lake to walk around. The location is very clean, and the staff is helpful and friendly! We plan to continue to visit a couple times a year!

We recently stayed at this KOA for an extended period of time because my daughter who lives in Iowa was having a baby. We have nothing but good things to say about this KOA. The facilities are nice and set up for ease of use. There is a gas/diesel station on site. The store stays open until 10:00 p.m., and the staff was friendly and helpful especially Karl. This is an exceptional KOA campground!

Very customer friendly staff. Great location for warmer camping. Beach, swimming, beach volleyball, tropical atmosphere, and more would be great for family reunion and group meetings.
