Tree Planting Celebration with Mountains to Sound Greenway


Join more than 200 volunteers at the annual tree planting celebration at the park and plant a tree (or shrub) together! The celebration this year will include food, music, and plenty of tree planting fun for the whole family.

This year is extra-special. It marks the 200,000th tree planted in partnership with Carter Subaru. Their support has helped Mountains to Sound plant forests throughout the Greenway, and they can’t wait to continue– with your help, of course!

This event is part of 20 years of restoration along Issaquah Creek, supporting salmon habitat in this critical area. Celebrations will begin promptly at 10 a.m. and include planting activities, education stations (sign-up day of), coffee, light lunch, snacks, and more.

Planting events are great for individuals, families, groups, and work teams. With a goal of 1,000 native trees and shrubs to be planted, you will all be able to plant a tree and leave a bit muddier! No experience necessary, and all training provided. 

Register here to join us at this year’s event, and please reach out to if you have any additional questions.
