The park is also known as Fowler Woods (due to its proximity to Fowler Middle School) and as Summer Creek Natural Area (because Summer Creek flows through the property). The 48 acre park is the largest nature park in Tigard and was purchased by the city of Tigard through a bond measure passed in 2010.

Located at the confluence of Summer and Fanno Creeks, Dirksen Nature Park is home to a variety of ecosystems that support a strong diversity of plant and animal species. The education center is an off white portable classroom with a small blue Tualatin Riverkeepers sign on it.

For more information about the current status of Dirksen Nature Park’s restoration, access, and infrastructure improvements click here.

The Education Center at Dirksen Nature Park is located at 11130 SW Tigard Street, Tigard OR. When mapping to the education center be sure to enter the correct address, the triple “1” often throw people off. Also, do not map to “Dirksen Nature Park” it will take you to the wrong Park entrance.
