Robert Mattke Park in Fredericksburg serves as the western trailhead for the Plum Creek Bike & Nature Trail, offering over 5 miles of scenic biking and walking trails (3/4 paved, 1/4 crushed rock) that wind along Plum Creek.

The park features a gazebo shelter and butterfly garden, providing a pleasant starting point for recreational access to the East Fork Wapsipinicon River area. Parking is available at the park entrance on 270th Street.
