Very nice new park. Lots of amenities, spacious sites. Would suggest more signage to find park. Will definitely re-visit.

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.

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

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.

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.

The ground is eroded and rough in spots. I turned my ankle while setting up and walking to the dog park. I am OK but it may be an issue to someone else.
