Overview

Union Grove State Park offers a tranquil retreat for travelers seeking the quiet beauty of rural Iowa. Centered around a picturesque 110-acre man-made lake, the park is renowned for its lush greenery and rolling landscapes. It provides a peaceful atmosphere where the sounds of nature replace the hum of highway traffic, making it a hidden gem for those who enjoy the slower pace of the Midwest and a connection to the outdoors.

Location & Surroundings

Situated just outside the charming town of Gladbrook, IA, the park is nestled within the heart of Tama County. The surrounding area is characterized by rolling timbered hills and expansive farmland, offering a quintessential Iowa experience. The lake itself is bordered by dense woods and prairie, creating a secluded environment that feels private and immersive, providing a scenic backdrop for every visiting RVer.

Many sites are well-shaded by mature trees, providing relief during warm summer afternoons while offering a scenic view of the water or the surrounding forest.

Nearby Attractions & Things to Do

Outdoor recreation is the primary draw here, with fishing and boating topping the list of popular activities. The lake is well-stocked with crappie, bluegill, and channel catfish, providing ample opportunities for anglers.

We enjoyed our weekend stay here. It’s a small campground with 11 or so spots and two cabins. There are toilets and showers. Each camping spot had electricity and water. Even though the campground was full this weekend it was quiet and peaceful. There is a good size lake a couple of shorter hiking trails. We picked this location due the reasonable price and it was right in between home and Ames for the football game.

The lake is absolutely beautiful! There are many spots to stop and have a picnic. The waterfall is pretty but took us a bit to find - there is a small gravel parking area by the intersection of C ave & 220th street. (I'm 99% sure that's where it is.) Walk over to the bridge and you can't miss the waterfall. I only give the 4/5 rating because the walking paths could have been better maintained or trimmed back but I also understand nature takes over rather quick. The guard rail at the top of the waterfall was very loose too so don't lean against that! Overall it was a great experience and I will be returning :)

A small yet beautiful park. There are two well maintained cabins in the campground that overlook the lake and would be a perfect retreat for a family looking to step away from the daily hustle. We enjoyed a small hike and picnic on the southern edge of the lake, it is rare to enjoy the sound of falling water in Iowa. While not a big destination, it was a cute stop to gain 300 pts on my Iowa State Parks Passport!

The campsite itself is fine expect one pretty big issue. THE FLIES!!!! I understand we’re outside but it was really bad. We had the citronella candles, wristbands, bug spray, fly strips and still had to use 2 fly swatters with no reprieve. The video is after 3 founds of battle all day.

Terrible lake quality. I don't know who dropped the ball but the fishing is no good waters unsafe to swim in. Great area but the lakes in desperate need of attention. I know its been dredged it takes time. This isn't a time issue anymore its water quality. I thought their's supposed to be airaraters but I never seen them running.
