Written By Issa Moffett

Your Guide to Nature Events in Seattle and Across the Greater Puget Sound and Olympic Peninsula Region

Earth Day week is here, bringing a full lineup of restoration events, bird walks, plant sales, and community science. Birds are migrating, tides are returning, and longer days mean more time to get outside!

As always, check event pages for updates, cancellation, registration or gear requirements before heading out, and be mindful stewards of the land, leave no trace, respect wildlife, and care for shared spaces.
