🦅

Steens Mountain · Bortle 1–2

The fault-block mountain rises to 9,700 feet above the Alvord Desert — one of the most dramatic landscapes in Oregon. The Alvord hot springs and desert playa at the base provide foreground, while the summit ridge gives above-the-horizon dark sky in every direction. Check tonight's sky →

🏜️

Hart Mountain · Bortle 1–2

Remote antelope refuge in the Oregon high desert with Bortle 1–2 skies and almost no visitors after dark. The hot spring at the campground makes it a legitimate overnight destination — soak in 100°F water under the Milky Way. Check tonight's sky →

🔥

Crater Lake · Bortle 2–3

The deepest lake in the US sits in a caldera at 6,000 feet elevation. The lake surface reflection and Wizard Island make exceptional foreground. Snow at the rim is common into June — check road conditions before planning. Check tonight's sky →

🌊

Oregon Outback · Bortle 1

The high desert lake country south of Burns is one of the least light-polluted regions in the continental US. No official park designation — just genuinely remote high desert with almost no human light sources for miles. Check tonight's sky →

🌾

Jarbidge Wilderness · Bortle 1

Straddles the Oregon-Idaho border in one of the most remote corners of the lower 48. Bortle 1 skies with canyon and mountain foreground. Long drive on unpaved roads — serious commitment but serious darkness. Check tonight's sky →

🌿

Palouse · Bortle 3–4

The rolling wheat fields of eastern Oregon and Washington are more accessible than the remote desert locations. Peak season is late spring when the fields are green and early summer before harvest. The gentle hills create unusual curved horizon compositions. Check tonight's sky →

Before you go

Planning Tips for Oregon

Oregon Milky Way season is May through September. Eastern Oregon locations are best — western Oregon's coastal marine layer and Cascades weather make conditions less predictable. Check StarCast for transparency specifically: even clear nights can have poor transparency from wildfire smoke in late summer.
