Sehome Hill Arboretum

It comprises 175.5 acres (71.0 ha) of second growth forest on Sehome Hill, adjacent to the campus of Western Washington University.

The park offers students and city dwellers over 5 miles (8 km) of public trails for walking and running and, in some areas, bicycling.

Unique features of the park include an 80-foot (24 m) wooden observation tower atop Sehome Hill, with aerial views of Bellingham Bay to the south.

There is also a large tunnel, hand cut into rock in 1923, originally used for car traffic in the early 1900s.

Its tall, thin shape shows its creation for cars like Model T Fords of the day.
