Seattle Naturalists’ Event Roundup: April 13th - April 19, 2026
Your Guide to Nature Events in Seattle and Across the Greater Puget Sound and Olympic Peninsula Region
With International Dark Sky Week underway and a new moon on the horizon, this is prime time for stargazing, astrophotography, and reconnecting with the night. By day, spring migration is in full swing, low tides are returning, fungi, plant workshops, and stewardship!!
