THE SUN IS OUT across the Puget Sound, and the region is fully waking up to early May energy. Migratory birds are active across shorelines, parks, and forests, wildflowers are blooming in prairie and woodland spaces, and low tides are revealing rich intertidal life along the coast. Here is your weekly event round from a variety of nature organizations from Monday, May 4th to Sunday, May 10th.

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