This year International Dark Sky Week is April 13-20, 2026.
International Dark Sky Week is a global celebration of the natural night, inviting everyone to step outside, look up, and rediscover a sky filled with stars.
IDSW introduces newcomers to the idea of light pollution and highlights how protecting darkness supports wildlife, human health, and our own sense of wonder.
There are many simple and memorable ways to take part. Enjoy a campfire and share stories, connect with a local astronomy club to look through a telescope or learn the constellations, or head out on a night hike to experience the world after sunset. You can also attend a presentation about light pollution, support astrotourism in your community, talk with local leaders about better lighting practices, or make small changes around your own home to help preserve the night.
If you are in the valley, you can join one of the many Dark Sky Week programs happening throughout the week, each designed to help you experience the night in a new way.
See below our list of events, descriptions, and ways to register for the event.
IDSW Event Descriptions
Astronomy for the Soul: Lake Wenatchee State Park
Settle in along the peaceful shores of Lake Wenatchee and let the night sky become your guide to restoration. In partnership with WVAC, this program invites visitors of all ages to lean back in a chair or stretch out on a blanket as we explore constellations and the awe‑inspiring structures that shape our universe.
Rooted in the Park Rx philosophy, Astronomy for the Soul encourages slowing down, breathing deeply, and reconnecting with the natural world as a pathway to well‑being. The gentle rhythm of the lake, the quiet of the forest, and the brilliance of the stars create a calming space where you can feel grounded, safe, and fully present.
Give yourself permission to unwind, refill your cup, and let the night sky ease the stress of everyday life—one peaceful moment at a time.

CDLT Cosmic Hiking
CDLT Cosmic Hiking offers a chance to explore the half of nature most people rarely experience: the night. Join WVAC and the Chelan‑Douglas Land Trust at the Mountain Home Road Trailhead in Leavenworth for a guided ridge‑line hike with sweeping views of the Leavenworth valley and the surrounding mountains. Along the way, the group will pause at several points to dive into individual constellations, their stars, and the stories they hold across different cultures. At the final stop, all of these constellations come together in a larger narrative of the cosmos.
Trail conditions may require a change of venue. If so, the program will move to the Jacobsen Preserve Trailhead in Wenatchee.
