Bob Siebenthaler Natural Area honors long time support of land stewardship and former MetroParks commissioner Bob Siebenthaler. The short loop trail through the natural area takes hikers to one of the best locations to see spring wildflowers and an exceptional mature forest. Hikers can also connect to the 22-mile Twin Valley Trail (TVT). Relax by the banks of the Twin Creek, one of the healthiest waterways in the state. The Old Mill Campsites offers visitors an overnight experience in Germantown MetroPark (camping permit required). 

Over 300 different kinds of plants have been identified in this area making it one of the most diverse places within Five Rivers MetroParks. Be sure to come back often to explore and experience seasonal change in this remarkable area.
