Union Park is a 51-acre park in Des Moines, full of nostalgia and fun for all ages! Unique park highlights include a working carousel, formal gardens, and a splash pool. But that’s not all – visitors also enjoy the green space, playgrounds, picnic areas, and more.
A Brief History of Union Park
The area around Union Park was once called Thompson’s Bend, so named after the original landowners. The City of Des Moines bought 27 acres from the Thompson family and established Union Park in 1894. And in the early years, it had an aviary, pavilion, and greenhouse.
In the 1970s, a rocket slide got installed and became a favorite among kids. And then, in 1998, a historic carousel came to Union Park, thanks to Buz Brenton of the Des Moines Heritage Carousel Association. The association worked with the city council on an operating agreement. As a result, the carousel now offers tens of thousands of rides to kids each year.
The historic park entrance underwent restoration in 2012. And formal gardens have always been a part of the park, and you can still stroll through them today.


Things to Do at Union Park
Ride the Heritage Carousel
Heritage Carousel is a nostalgic, turn-of-the-century replica carousel, complete with band organ music! It’s worth stopping for a ride on one of 30 animals (or chariots) on this 37-foot, 3-row wood carousel. Another great feature is its wheelchair accessibility.
Not only is the carousel fun, but it’s a fantastic work of art! Carousel animals are all hand-carved and painted. Plus, it features paintings of landmarks around the Des Moines area, like the Botanical Garden and the Salisbury House.
Cost to ride:
- $1 for adults
- 50 cents for kids (adults standing beside small children ride free).
- Season passes, wristbands, punch cards, and tokens are available for frequent riders.
Hours of operation:
- Memorial Weekend – August (when school starts): Tuesday – Sunday, 11 am – 7 pm.
- Late August – September, open on weekends only.
- Available for private rental.
Adopt an animal!
To keep rides affordable, the Des Moines Carousel Foundation relies on donations. Adopting (and naming!) carousel animals, you can help them out! For more ways to contribute, see the website.
See the Heritage Carousel of Des Moines website for more information on the carousel.

Play at the playgrounds
A visit to the Union Park Rocket Slide is a must. And other play structures around the park are fun for all ages.
Cool off at the splash pool
The zero-depth entry splash pool and pad with sprinklers are on the park’s north end. Not only that, but it’s near the carousel and other playgrounds, so the kids can have a ton of fun. Did we mention it’s free!? For hours, see the city’s website.

Explore the gardens
A formal garden with several planted areas is on the park’s southeast side (between Thompson and E. 9th). Stroll through the gardens during the summer months to see what plants are blooming. Or sit on one of the many benches and enjoy the surroundings. You can also rent the area for your next event!
Play tennis
Make a game of tennis part of your visit to Union Park! The tennis court is on the park’s north side (Guthrie Ave), near the splash pool.
Have a picnic
Union Park is a beautiful place to picnic. There’s so much to do and see there you’ll want to pack a lunch or grill dinner. Picnic benches are in several areas at the park.
The open-air shelter can be reserved and is otherwise first-come, first-serve. There are also two enclosed shelters available by reservation. For more on rentals, see the Des Moines Park Shelters page.
Winter activities at Union Park
Sled down the hill on the park’s west side! You can also cross country ski through the park’s green space or explore the park on snowshoes. Snowshoe rentals are available at Birdland Marina at Captain Roy’s.
