Scenic Trails & Tower Views at Sehome Hill Arboretum

Sehome Hill Arboretum is a peaceful forested park located in Bellingham, Washington, offering a refreshing outdoor retreat inside the city limits. Known for its combination of city convenience and natural splendor, this 180-acre green space sits close to the university district and provides visitors with lush old-growth evergreens, moss-covered trails, and diverse native plants that reflect the temperate Pacific Northwest environment. The arboretum is particularly popular because it balances easy access with a feeling of immersion in nature, making it a favored spot for both casual walkers and outdoor enthusiasts.

One of the arboretum’s defining features is the historic wooden observation tower that sits at the hill’s summit. From here, visitors enjoy sweeping panoramic views of Bellingham Bay, the San Juan Islands, and, on clear days, the snow-capped Canadian coastal mountains. Along with natural beauty, the arboretum preserves a slice of local history—the land once housed a granite quarry, and remnants such as old tunnels are still visible along the trails today. Winding paths vary from paved sections to more rustic, rocky routes, threading through dense fir and cedar forests. Birdwatchers often spot native songbirds, adding to the area's quiet charm.

Visitors often praise the well-marked and maintained trails that provide variety without steep climbs, making it an approachable destination for all ages. It is important to note that some trails can be uneven and overgrown in places, especially in wetter seasons. The arboretum has no public restrooms, and while the observation tower offers incredible views, it is not wheelchair accessible. Overall, Sehome Hill Arboretum stands out as a serene pocket of wilderness with notable vistas right in the heart of Bellingham.
