About This Access Site
Idle Isle Park offers a dedicated boat launch on Little Muskego Lake in Muskego, Wisconsin. This 7-acre community park provides convenient access for kayakers, canoeists, and motorboats, with a maintained boat ramp and dedicated trailer parking area. The facility includes restrooms, a fishing pier, and a small swimming beach. **Note:** All vehicles require payment to enter the park; launch fees cover both boat launching and vehicle/trailer parking with no additional charge.

The concession stand is open seasonally (Memorial Day through Labor Day, Monday-Friday 10 AM–5 PM, Saturday-Sunday 9 AM–4 PM, weather dependent). Before visiting, check current conditions and any seasonal closures—recent improvements have occasionally required temporary launch closures. If the main launch is unavailable, three alternative launches serve Little Muskego Lake, though parking may be limited at those sites. The park's location at W182S6666 Hardtke Drive makes it easy to find and provides a solid base for exploring this popular local lake.
