🌾

Palouse · Bortle 3–4

The rolling wheat fields of the Columbia Plateau are one of Washington's most distinctive Milky Way landscapes. The gentle hills create curved horizon compositions unlike anything in the Cascades. Spring planting season and early summer produce the most vivid green fields. Check tonight's sky →

🏔️

North Cascades National Park · Bortle 2–3

Remote alpine terrain with glaciated peaks and turquoise lakes as foreground. The park's interior is only accessible by foot or boat — but the dark sky over Diablo Lake from the overlook is reachable by car and exceptional. Check tonight's sky →

🌊

Olympic Peninsula · Bortle 2–3

The remote coastline of Olympic National Park — Ruby Beach, Rialto Beach, and Kalaloch — provides sea stack and driftwood foreground under dark Pacific sky. Fog is the primary variable: check FogCast alongside StarCast before making the drive. Check tonight's sky →

🦅

Okanogan Highlands · Bortle 2

The remote northeastern corner of Washington near the Canadian border is some of the darkest sky in the state. The high plateau terrain and minimal population creates an accessible dark sky corridor that most Washington photographers don't know exists. Check tonight's sky →

🌋

Mount Rainier National Park · Bortle 3

The volcano is one of the most dramatic single-object foregrounds in the Pacific Northwest. Reflection Lakes and Paradise offer strong compositions. Cloud cover is the limiting factor — the mountain creates its own weather and clear nights require checking conditions specifically. Check tonight's sky →

🏕️

Colville National Forest · Bortle 2–3

Northeastern Washington national forest with dark sky, minimal development, and granite mountain foreground. Less known than North Cascades but significantly more accessible for overnight camping without backcountry permits. Check tonight's sky →

Planning Tips for Washington

Washington's split personality by geography makes location choice critical. Eastern Washington east of the Cascades has significantly more clear nights than the west side. Check StarCast specifically for transparency — smoke from summer wildfires can affect eastern Washington significantly in July and August.
