About Muskego Park
Muskego Park is a 193-acre Waukesha County park in Muskego, Wisconsin, purchased in 1958 as the county's first regional park. For anyone hunting places to swim in the county, it is a straightforward swimming hole: an official beach with a roped-in shallow swim area, alongside 60 acres of old-growth hardwood forest, trails, and picnic facilities.
The park sits on Janesville Road in Muskego and combines a developed beach/picnic area with 60 acres of hardwood forest recognized as a Wisconsin State Scientific Area and inducted into the Old-Growth Forest Network in 2021; trails for hiking, biking, and horseback riding wind through the property.
Swimming at Muskego Park
Swimming is confined to a designated roped-in shallow area of a sand beach; there are no lifeguards, so swimming is at one's own risk. The county tests the water weekly for E. coli and blue-green algae and closes the beach if bacteria exceed 1,000 CFU/mL, which points to a still, monitored swim area (pond-like) rather than flowing water.
How to get to this swimming hole
The park entrance is at S83 W20370 Janesville Road, Muskego, WI 53150; a vehicle permit (annual membership or daily pass) is required to enter.
Parking: On-site parking is listed among the park's standard facilities.
The hike in
Multi-use trails for hiking, biking, and horseback riding wind through the park's 60-acre old-growth hardwood forest (Muskego Park Hardwoods State Scientific Area), but these are separate recreational trails, not the access route to the beach.
The swim beach is a drive-up facility reached directly from the on-site parking lot; no trail hike is needed to reach the water. Exact walk distance/time from the lot to the sand beach was not specified in official sources.
Plan your visit
Bringing kids
OK with supervision
The beach has a designated roped-in shallow swim area, which suits young kids, but the county explicitly states there are no lifeguards on duty, so direct caregiver supervision is required. Weekly E. coli/blue-green algae testing (closure at 1,000 CFU/mL) is an added safety backstop, and dogs are allowed in the same sand beach area as swimmers, which some families may want to factor in.
Parking

Backstory
