Swimming in Johnston: the indoor Summit pool, a free splash pad, and the lake nearby.

Here's the honest version: Johnston doesn't have an outdoor municipal pool. What it does have is a year-round indoor community pool at Summit Middle School, a free splash pad at the Town Center for hot afternoons, and, a few minutes north, the beaches at Saylorville Lake. Between the three, you're covered. Here's where to go and what it costs.

The quick version

Johnston has no outdoor municipal pool. For lap or open swim, use the indoor Summit Middle School pool (9500 Windsor Parkway) through Johnston Community Education - roughly $5 cash per visit, mostly weekend hours. For free water play, the Splash Pad at the Town Center runs Memorial Day-Labor Day, generally 10 a.m.-8 p.m. For outdoor swimming, head to Saylorville Lake's beaches just north of town.

The public pool

Does Johnston, Iowa have a public pool?

Summit Middle School Pool (indoor)

Johnston's public pool is indoor, at Summit Middle School, 9500 Windsor Parkway. It's an 8-lane, 25-yard pool that doubles as a community space, run by Johnston Community Education. Public open swim and lap swim are offered mainly on weekends - the exact days and times rotate, so check the monthly Community Education schedule before you go.

Lap swim is $5 cash per visit paid at the pool office (you'll sign a waiver), or grab a $45 punch card if you're a regular. Because it's a school pool, availability works around swim lessons, team practices, and the school calendar - the Community Education aquatics schedule is the source of truth.

Free & easy

Is the Johnston splash pad free?

Yes. The Splash Pad at the Town Center is free and open to everyone, with sensor-activated water features the kids trigger by stepping on the pads. It runs daily from Memorial Day through Labor Day weekend, generally 10 a.m. to 8 p.m. It's unsupervised, so an adult needs to tag along, and pets aren't allowed in the splash area. It sits in the Town Center park alongside a playground, basketball courts, and walking paths, so it's an easy stop.

Want to swim outdoors?

Since there's no outdoor pool in town, the closest open-water swimming is at Saylorville Lake, just north of Johnston, which has public swim beaches in season. It's a lake, not a chlorinated pool - check posted conditions - but it's the local outdoor swim. See our Saylorville Lake guide.
