Washington Park Arboretum Trail

Route Description for Washington Park Arboretum Trail

The Washington Park Arboretum is 230 acres of pure beauty, featuring trees and flowers from countries around the world that border the Pacific. There are endless groves of trees, a gorgeous azalea feature, and unique flowers. Birdwatchers also flock (pun intended) to the park to see the range of species that come to enjoy the greenery.

This walk covers the arboretum from top to bottom, but we recommend taking the time to explore some of the features of the park that the trail doesn’t include. Stop into the greenhouses, stroll through the meadows, sit for a while in the Japanese gardens, or stroll the coastline on the islands.

While you can visit the arboretum throughout the year, we recommend coming in the springtime for the best possible experience. The Azalea Way, which is the main road through the arboretum, is in full bloom in the springtime.

Begin from the visitor center. While you can loop either way, we’ll describe this trail to end with the Azalea Way, which is a nice conclusion to your day. Walking north, the path splits three ways just past the maintenance building. Take the middle trail. You’ll cross the water onto Foster Island and head to the far shore for a view of the water.

From the shore, turn back and cross over to the mainland arboretum. Retrace your steps to the three-way junction and through the visitor center. Walk past the greenhouse and then turn right past the Sun House and the Shade House. You’ll walk down alongside the meadow and the nursery. Notice the groves of trees and plants as you go, each grouped together in impressive gardens.

Walk past the pond and then keep left at the junction. You’ll pass the legumes and then the witch hazels, taking a right and then another right to weave through the Pacific Connections Garden. Keep an eye on your map or route as you turn sharply left, right, and then left again onto a path heading south. Turn right twice to get onto the Arboretum Loop Trail, then take a slight right onto Azalea Way.

Admire the vibrant pink blooms as you wander back through the park. There are a few interesting trails, but you’ll keep going straight ahead back to the visitor center. If you’re here in the right season, the azaleas are truly stellar, so no need to rush this last section.

When you’re back where you began, you can either depart or find a new trail to explore.
