A county park with a lagoon, ballfields and the Oak Leaf Trail, plus what the 2026 pool closure means and where to go next.
McCarty Park is the green patch on West Cleveland Avenue where a lagoon, baseball diamonds and a stretch of the Oak Leaf Trail share the same ground. Anyone looking up McCarty Park West Allis should know it is a county park, not a city one, and that its pool was set to stay closed for 2026. A 2026 CBS58 report says that pool was set to stay closed for the summer, so this guide starts from what is actually there: a walking loop, fishing water, play areas and a trail that runs toward downtown Milwaukee. Pair it with the West Allis attractions and a free afternoon gets a plan.
What McCarty Park is, and who owns it
McCarty Park sits at 8214 W. Cleveland Ave. and belongs to the Milwaukee County Parkway System, and the pool closure was announced by County Supervisor Justin Bielinski.

A reviewer describes a play area just outside the pool gates, and one visitor found the park beautiful in the early hours.
The pool: built in 1959, set to stay closed in 2026
The McCarty Park pool was not going to open in summer 2026. CBS58 reported on April 23 that the slide needed repairs, that attendance fell after the pool broke the previous year, and that lifeguards had already been assigned elsewhere.
County Supervisor Justin Bielinski said the repair estimate was something over $10,000, with the exact cost not yet known, and said he was just as disappointed as residents. FOX6 repeated the closure on May 26, 2026, when a county committee approved a splash pad grant for Washington Park Pool.
The pool has a longer record than that headline suggests. The Wisconsin Historical Society dates the concrete swimming and wading pool to 1959 and says a waterslide arrived in 2011, and it dates the bathhouse beside it to about 1960.
Google reviewers who swam there in earlier summers mention two diving boards, lap lanes, a slide and a kiddie pool, and one calls it a place where kids always had a blast.
The CBS58 report adds that the wading pool has a separate management team and could still open, but it does not say whether it will, so treat any water play at McCarty this year as unconfirmed. County officials pointed families to Cool Waters aquatic park, which the report put about four miles away.
Walking the lagoon and joining the Oak Leaf Trail
Reviewers describe a walkway around the park and its water, and that loop is the easiest reason to come. One reviewer calls it a nice walkway around the park, another describes a creek crossed by what looks like two to four bridges, and a third describes a bench in the shade by a family of geese and ducks.
The county's trail page says the Kinnickinnic Line of the Oak Leaf Trail passes through McCarty Park on its way along the Kinnickinnic River Parkway. That line runs about 15 miles from the Museum Campus to Hart Park, so a walk here can turn into a long bike ride toward downtown Milwaukee.
The page adds that trail segments inside county parks are generally open from 6 a.m. to 10 p.m., and that some stretches share the road with traffic, so a first ride deserves a look at the map.
One caution comes up in the reviews. A visitor warns that a waterway and pond cut through the park, so parents of small children should keep them close.
Fishing is part of the park too. A park-guide site describes the lagoon as a fishing spot, and the same page records an urban birding scene with herons among the sightings.
Parking, access and picnic space
Google's profile for McCarty Park shows free street parking, and it also lists paid lot and street parking, so read the signs where you leave the car.
The profile marks a wheelchair-accessible entrance, parking and restroom, and tags the park as good for children.
For a group, the county rents the McCarty Park Pavilion online with a maximum capacity of 80. The county's rental page does not list a kitchen or restrooms for this pavilion, so ask when you book.
The park has hosted one-off events as well. A 2018 TMJ4 story covered a 10,000-square-foot puzzle maze that set up here for the summer, and a 2019 Shepherd Express listing showed a Traveling Beer Garden tour stop at the park. Ask the county about anything current.
Breakfast or lunch a few blocks away
The nearest sit-down meal is Michael's Family Restaurant, about 0.3 miles west of the park. It serves traditional American dishes with daily specials.
More diners, pancake houses and supper clubs are covered in the West Allis restaurants roundup.
Greenfield Park, the bigger neighbor to the west
If McCarty Park feels small, Greenfield Park is the larger version, about 2.7 miles west and sitting on the Waukesha County line.
The county's trail page says the Root River Line of the Oak Leaf Trail meets the New Berlin Trail in Greenfield Park. A reviewer who runs a 5k route there links up with the Oak Leaf Trail to complete it.
Golfers have a reason to make the trip as well. Greenfield Park Golf Course, a par-69 course added in 1923, is described by reviewers as mostly straight with narrow fairways, and others mention views from holes 14 and 15, and the park pavilion holds 75 for rentals. You can read more on the Greenfield Park Golf Course page.
The park once had a Works Progress Administration pool, and Living New Deal says its water was warmed in small lagoons before it entered the pool. Today the park's Google summary describes a family water park with waterslides, so this is the place to point swimmers while McCarty's pool was set to stay closed, though check the season first.
Pairing the park with the State Fair neighborhood
Wisconsin State Fair Park lies about 1.7 miles north of McCarty Park, which makes the park a calm alternative on a fair day. Anyone driving to the fair should read up on parking at the Wisconsin State Fair beforehand, and WI State Fair is the event's own page.
The fair has been in West Allis since 1892, and the 175th fair ran August 6 to 16, 2026. FOX6 said the fairgrounds stretch from 84th Street east to 77th Street.
A few other stops round out a day. The farmers market, about 1.6 miles northeast, has been a community staple since 1919, and The Picklr West Allis, about 1.7 miles west, has 10 indoor pickleball courts. Visitors staying overnight can look at the hotels near the interstates before they book.
What to expect, honestly
McCarty Park is a neighborhood park, not a destination with a gift shop. The pool was set to stay closed this summer, the county's pavilion page lists no hours or restroom details, and the lagoon is described as a fishing spot.
Bring a snack and a bike, take the lagoon loop first and decide on the Oak Leaf Trail when you see how the weather behaves. A pool that was set to stay closed for repairs still leaves McCarty Park with its lagoon, its ballfields and its trail.
