There are no bike trails at the park, but Juneau County's 15-mile-long Omaha Bike Trail can be reached from the park via County Highway W to County Highway C into Camp Douglas. The Omaha bike trail also connects to the Elroy-Sparta State Trail and 400 State Trail in Elroy.
Mill Bluff is on both sides of Interstate 90-94. Take the Oakdale exit #48 or Camp Douglas exit #55 to U.S. Highway 12/16. Follow signs to the park.
