Mt. Hood sits about 50 miles east of Portland, so the city’s glow stays low in the western sky. Lakes like Timothy, Lost and Frog open up a wide sky, and in winter the Sno-Parks, at about 4,000 to 6,000 feet, give you the longest nights of the year. Pick a clear night with little moon, give your eyes half an hour to adjust, and the sky fills in.
Clouds, the moon and darkness decide what you will see. Check all three the day you go, and again before you lose signal: some forest roads have no cell service at all.
Open the National Weather Service point forecast for Government Camp, or move the point to your spot, and look at the sky cover for the hours after dark. The lower the number, the clearer the sky.
A bright moon washes out faint stars and the Milky Way. Aim for nights near the new moon, or wait for the moon to set. NASA's moon phase table lists every new and full moon.
The sky isn't fully dark until about 1.5 hours after sunset. At Government Camp that's around 6:30 p.m. in early November, but not until about 11:30 p.m. in late June.
Check weather, road conditions and alerts before you drive up. Forest Service roads aren't plowed, and fire closures can shut whole areas.
Lakes give you open sky and a mirror for the stars. Campgrounds let you stay out after dark, so book a site if you want the whole night. Seasons below are for 2026 and change every year.
Portland General Electric runs this big south-side lake with the Forest Service. West Shore day use is open 6 a.m. to 10 p.m., and campgrounds such as Hoodview open the Friday before Memorial Day.
Travel Oregon picks this north-side lake for stars reflected in still water. The resort campground ran May 1 to Oct 10. The day-use store and boathouse keep 8 a.m. to 5 p.m. hours, so camp if you want the night.
Right off US 26, east of the 26/35 junction. The campground (May 22 to Sep 30) and the Sno-Park are both open 24 hours.
South of Timothy Lake on FR 58. The campground and day use are open 24 hours in season (May 23 to Oct 12). No swimming in the lake.
A fire lookout you can rent Nov 1 to May 31 for $85 a night on Recreation.gov. From Dec 1 to Apr 30 you reach it only by ski, snowshoe or snowmobile, 3.5 miles from Skyline Sno-Park.
The classic Mt. Hood reflection, but day use is sunrise to sunset only. To stay after dark, book the campground (May 22 to Oct 31).
Know where you can be after dark. Trillium Lake day use is open sunrise to sunset only, so after sunset the lake is for registered campers. At Timberline, camping isn't allowed in the parking lots or anywhere inside the ski-area boundary, and the Main and Salmon River lots are marked no overnight parking.
The bright center of the Milky Way rises in the southeast, in Scorpius and Sagittarius, and looks best when the moon is new or a thin crescent. From Mt. Hood it never climbs more than about 16 degrees above the southern horizon, so pick a spot with an open view to the south. At lakes where the mountain fills the northern view, like Trillium, the core is behind you.
The core is up only in the last hours before dawn.
The easiest months. The core is up around midnight, but full darkness is short.
Look soon after dark. The core sets a little earlier each week.
The core isn't up during full darkness. Enjoy the winter stars instead.

Shower dates change every year. These peaks and moon phases are for 2026-27, from the International Meteor Organization and the American Meteor Society, and the two sometimes differ by a night. Hourly rates are best-case numbers.
Winter brings the longest nights. Around Dec 21, full darkness at Government Camp runs from about 6:15 p.m. to almost 6 a.m. Lake roads such as Trillium's are gated, so the Sno-Parks become the place to go, and an Oregon Sno-Park permit is required Nov 1 to Apr 30.
Allowed at Mt. Hood Sno-Parks except Timberline Lodge, the Summit rest area and the Government Camp Loop. At Trillium Sno-Park, park overnight only in the marked spots on the far east side.
White River West (4,200 ft) and Bennett Pass (4,700 ft) sit on OR 35. Rose City Astronomers have held member star parties at White River. Bennett Pass's lot has a 5% grade, so good tires are a must.
Plows usually come through at night. Park toward the middle of the lot, don't block the berms, move your car between nights, and don't camp on snow within 300 feet of the lot.
Skibowl lights 37 runs for night skiing until 10 p.m., and Mt. Hood Meadows also runs night skiing in midwinter. Keep the lit slopes out of your view.

Do
Don't
Drive forest roads with care after dark. Forest Service roads aren't plowed or maintained for winter travel, GPS apps won't show which ones are snowed in, and log trucks won't make room for you. On the highways, a "Carry chains or traction tires" sign means they must be in your car, and "Chains required" means put them on. Dress warmer than you think: feeling cold and sluggish or having trouble thinking clearly are signs of hypothermia.
Yes, on a clear night with little moon. Mt. Hood is about 50 miles east of Portland, and a light-pollution map shown at a 2024 Wasco County meeting rated the Mt. Hood area class 3 on the Bortle scale, against class 7 for Portland. No sky meter sits on the mountain itself, so there is no official darkness reading. At the measured Portland sites, the Milky Way doesn't stand out.
Only if you're camping there. Trillium Lake day use is open sunrise to sunset only, so after dark the lake is for registered campers. The campground ran May 22 to Oct 31 in 2026, and seasons change every year. For a spot that's open all night, try Frog Lake's campground or Sno-Park.
All Mt. Hood Sno-Parks except Timberline Lodge, the Summit rest area and the Government Camp Loop. At Trillium Sno-Park, park overnight only in the marked spots on the far east side of the lot. You need an Oregon Sno-Park permit Nov 1 to Apr 30: $4 a day, $9 for three days or $25 for the year, plus any agent fee. Follow posted signs, or your car may be towed.
Summer brings the Milky Way, but around the June solstice full darkness lasts only about three hours, from roughly 11:35 p.m. to 2:45 a.m. Winter nights are long, with full darkness from about 6:15 p.m. to 6 a.m. around Dec 21, but forest roads aren't plowed and you'll be at a snowy Sno-Park. In any season, pick a night near the new moon.
No. Goldendale Observatory became an International Dark Sky Park in 2010, but the status was rescinded in 2017. As of fall 2026 its telescope programs are paused because of staffing, and Washington State Parks is running movie nights and ranger talks through March 2027 instead. A free reservation is required to visit the visitor center or a program.
No. The University of Oregon observatory near Bend says it remains closed to the public until further notice, as of its Sep 25, 2026 update. When it reopens, note that its road isn't suited to passenger cars and high clearance is recommended.
Not in wilderness. Recreational drones can't take off from, land in or be flown from designated Wilderness Areas, and pilots must follow FAA rules everywhere. See our wilderness guide for where those areas are.
Usually. Trillium, Frog Lake, Clear Lake and Little Crater Lake day use cost $10 a vehicle, and only the $30 annual Northwest Forest Pass is accepted there; America the Beautiful passes don't work at Trillium. Timothy Lake sites are $10 a day or take the annual Northwest Forest Pass, a National Forest day pass or an Interagency pass. Lost Lake Resort takes only its own annual pass. In winter, Sno-Parks need an Oregon Sno-Park permit. See recreation passes.
