Sehome Hill Arboretum

Sehome Hill Arboretum covers about 175 acres of second-growth forest with Douglas Fir, Western Hemlock, and Western Redcedar trees spread throughout. The woodland also contains diverse shrubs and plant communities typical of the Pacific Northwest landscape.

Coal mining claims began in the 1850s, leading to tunnel construction across the hillside. After logging ended in 1906, the land was converted into a public park.

The arboretum serves as a meeting place where students and researchers monitor forest ecology and share findings about native tree species. Local visitors come here to connect with the regional landscape and understand how the forest changes over time.

The arboretum is accessible from the Bill McDonald Parkway entrance and offers over 6 miles of walking trails for pedestrians only. The grounds are open from early morning until dusk, with several additional access points throughout the property.

A wooden observation tower about 80 feet tall offers views of Bellingham Bay and surrounding peaks. A hand-carved tunnel from 1923 lets visitors walk through rock formations and experience the site's geological past.
