About Mckinley Marina Roundhouse
McKinley Marina is the largest marina in the southeastern part of Wisconsin. There are three sections. The Milwaukee Yacht Club has their headquarters in the Marina. There are multiple boat launches as well as many slips. Some winter storage is available. There are a few restaurants and snack shops to service the area. It is especially nice that even if you don't have a boat you can access the Marina. There is a long walkway that follows the breakwater; you can walk it or fish from it. Between the park and the Marina, you can spend an entire day here. It is a public marina (operated by Milwaukee county).
