July 4th Stargazing Aurora NYE World Events

Stargazing in Goldendale Observatory State Park Heritage Site, WA (2026)

Sky quality: see note
🌠 Perseids 2026 — a rare moonless peak. The shower peaks overnight Aug 12 into pre-dawn Aug 13 on a new moon, so the sky stays fully dark all night — the best Perseid conditions in years. Best rates are 2–5 AM local; just look up (meteors appear all over the sky). Before you go: YOU CANNOT SHOW UP. From these skies, expect a strong showing under clear, dark conditions — not the '100 per hour' quoted elsewhere. Full Perseids 2026 guide →
🌠 Geminids 2026 — the year's strongest shower, on a dark-sky night. Peaking overnight Dec 13 into the morning of Dec 14, on a thin waxing crescent moon that sets early evening, so the sky stays dark for the whole night. Good activity starts as early as 9–10 PM local — earlier than most showers — and climbs to a peak around 1–2 AM. Unlike almost every other shower, the Geminids come from an asteroid (3200 Phaethon, not a comet), producing slower, more colorful, easier-to-track streaks. Before you go: YOU CANNOT SHOW UP. From these skies, expect a strong showing under clear, dark conditions, outpacing even the Perseids. Dress for winter — it's a cold-weather shower. Full Geminids 2026 guide →

Clear-sky outlook

Washington State Park Heritage Site and public observatory — NOT a DarkSky-certified park. Houses a 24.5-inch Cassegrain reflector, one of the largest public telescopes in the United States. Observing is through the observatory's telescopes during structured, reserved programmes; there is no unstructured open-field stargazing here. Reservations are free but required; unscheduled visitors are turned away.

Sightlines: Hilltop site at 2,100 ft above the Columbia River with open horizons, but observing is through the observatory's telescopes during structured programmes rather than from an open field.

Programme Schedule

april to september: Solar programs 3-5 PM; evening programs 9 PM - midnight

october to march: Solar programs 2-4 PM; evening programs 7-10 PM

operating days: Thursday-Sunday per Washington State Parks; one secondary source says Friday-Sunday for autumn/winter. Verify the current calendar before travelling.

note: Live telescope views are offered during all programs, weather permitting. Reservations are required and free — book through the Washington State Parks online calendar.

Can you actually stargaze here? Booking or permit required — you cannot just show up

YOU CANNOT SHOW UP. Reservations are required to enter the visitor center or observatory, and Washington State Parks states plainly that unscheduled visitors and groups will be turned away. Reservations are free and booked through an online calendar; slots are removed as they fill. On operating days the park grounds close when the visitor center closes; on ALL OTHER DAYS the grounds close at sunset. There is no general-access stargazing here.

Common mistake: People assume an observatory is a place you can go and look at the sky. It is not — it is a booked programme venue on a five-acre site, with no camping, no overnight parking, and grounds that close at sunset on non-operating days. A conflicting FAQ on a Friends-of-the-observatory page says reservations are only needed for groups over five; the official Washington State Parks guidance supersedes it. Book first.

Entry fee: Admission and program reservations are FREE. A Washington State Discover Pass is required to park: $10 per day or $30 annual per vehicle.

Seasonal closures: Program times shift between the April-September and October-March schedules. Confirm on the official calendar.

1602 Observatory Drive, Goldendale, WA 98620. No camping and no overnight parking on the 5-acre site. Nearest camping: Brooks Memorial or Maryhill State Parks. Washington State Discover Pass required for parking ($10/day or $30/year).
