The site are in a downhill grade. The picnic tables are on a downhill grade. The sewer is almost unusable. It’s behind the camper and it’s uphilll. I most likely will not come here again. On a good note, the campground was clean.

We stayed at KOA Lost Island for 2 nights while on our way to a different destination. The KOA itself was nice and the staff very nice as well. It was HOT, so our shaded spot was perfect. Not sure we would have felt the same if we had a sight without any shade.

The campground is great but not so hot for tents.

Really nice park big sites

The sites were very nice spacious and clean. Not a lot of employees outside of the shop. The sites were pretty nice. Unfortunately, having no pool means the only swimming was in the pond. It smelled like sewage. It was down hill from all the camper dumpsites which concerned me. There was trash and what appeared to be a LOT of raccoon or small dog poop on the beach area. Too gross to use it.

Everything was great except for the beach. There were dead fish and goose poop everywhere. Definitely a turn off to this grandma.

Lots of dogs off leash. People don’t adhere to the speed limit. Other than that our stay was great until the next to the last day. The person on our passenger side pulled his 5th wheel in so his door was facing ours, put a big rug out, attached a leash to our tree and had kids toys everywhere. We didn’t say anything since we were leaving the next morning, but I don’t think it’s right to a

Short staffed so struggled finding my spot and took a few times around camp to locate. Bathrooms walls and floor could use a good scrub. Not a fan of the push button showers. No space or trees between sites so close to neighbors. Close to lots of restaurants and conveniences.

We wish you were closer to our home! Next time we are nearby, we would definitely stay again!

First off I want to say the staff are so nice!We haven’t stayed here since it first opened.It has igone down hill! The first cabin they put us in was absolutely disgusting. Stains on everything!I think the thing that bothered me the most was all the goose poop!There was a dead goose in the lake as well which depressed my kids.There are ways to deter geese!The lake to swim in was so gross with po

We lived in Waterloo for about 5 years in the late 90’s and decided to make a stop there for a couple of days on our way from Tennessee to Sturgis this year to revisit some of our past. This campground was amazing. We plan to come back and bring our son with us and spend a few days enjoying the camp and the waterpark that is close by. Very quiet and scenic campground and close to everything.

The only thing I would say is I would like to see a better playground for all ages. There are no swings or anything for real little kids 3 and under. Otherwise nice campground.

Always an enjoyable experience, we always just wish you had more trees.

It was beautiful, clean and the nicest staff. We got lost in Lost Island, it was perfect and I don’t think people realize this gem in Waterloo.

The bathroom and laundry room were covered with bugs. The swimming beach had goose poop and feathers all over. The office staff could not answer whether the lake water was monitored for bacteria, so we did not feel comfortable to swim. We would have preferred a pool. The campground layout was good.

The entire staff has an attitude problem, not welcoming at all. No Smiles, no Hello's, Nothing. It just seemed like all customers were a burden to them, instead of being guests. Guests we all are, and we have many choices. I will not recommend, nor return there again.

Nice campground, not very many employees compared to other KOAs. Beach was full of goose waster and pond full of moss.

I love how beautiful and clean the park is. The sites are so spacious. The beach is clean and the trail is relaxing and pretty packed with wildflowers. I love the attention to detail in the garden at the store. Gas station is such a great idea for campers! The employees were very helpful and sweet. Water park was a surprise and absolutely wonderful!

We went swimming at the little lake. The kids rode their electric scooters down. A teenager attempted to steal them. We told an employee and they said he is a problem every year. Why do you allow them to stay? Didn't feel safe after that situation and nothing being done. Site was nice but it was a haul to get up to the store. Store was clean and employees were friendly.

Our fourth time here. We like and know the area. However, this KOA continues to do the bare minimum in regards to upkeep, especially for a KOA Resort. Please take more care of this facility! Our fire ring had trash in it, bathrooms continue to have insects, and beach needs TLC. We want to be back, and each year we hope for better care of what could be an amazing campground. You can do better!

We love staying at the Waterloo KOA! The staff are very helpful, the cabin is always clean and ready, and it’s such a great location for keeping the kids entertained!

Great campground with lots of activities for families. Sites are wide and easy to access. Campground is located on a lake and has a beach. Didn't try it ourselfs, but the families there looked like they were having fun. Located next to a water park and an amusement park if your family needs more to do. The office has a well stocked store and a grill that delivers food items to your site.

Comfortable stay in a cabin. Loved the outside area and fire pit!

we were back in Waterloo for a family reunion and this park was our first choice. It's kept clean and well kept.

This campground is one of our favorites! The restrooms are always clean. The employees are so nice, helpful, and accommodating. We love KOA Lost Island and will continue coming back year after year! Thank you!

We stayed here doing a cross country road trip. We didn't get there until after dark. Our online registration had gotten mixed up, but the onsite person took good care of us, and even took us to our site. He was very appreciated! We would definitely stay here again if we were in the area.
