Sehome Hill Arboretum

​​​Escape to the Sehome Hill Arboretum, a 175.5 acre oasis located on the south side of Bellingham adjacent to the Western Washington University Campus. Wander along the trails through the native mature tree canopy. Classes are often taught here taking advantage of the natural habitat. Make sure to look up to see where the quarry once occupied the hill. Meander down the trail to find a geologic outcrop. Don’t forget to visit the observation tower, almost any of the trails in the Arboretum will lead you there. Climb to the top for sweeping views of the cityscape and Bellingham Bay. With 6 miles of trails you will be surrounded with the sounds of nature, have opportunities learn, observe, relax or have an adventure.

Master Plan

Bellingham Parks & Recreation Department, Western Washington University and the Sehome Arboretum Board of Governors jointly developed a Sehome Hill Arboretum Master Plan in 1978.  In the fall and winter of 2001-2002, the Board of Governors, WWU, and Parks & Recreation staff reviewed the existing Master Plan and initiated a Plan update.  Through a series of open houses, preliminary plans and alternatives were developed and discussed.  The Master Plan update reflects the incorporation of public comments and best management practices for the Arboretum.  The updated Sehome Hill Arboretum Master Plan was adopted by Bellingham City Council on February 9, 2004.
