Mount Tremper — a mountain peak in Ulster County, New York at about 829 m (2,720 ft) above sea level — is a classic subject for landscape photographers. It sits roughly 12.4 km (7.7 mi) NNW of Shokan.
Mount Tremper, officially known as Tremper Mountain and originally called Timothyberg, is one of the Catskill Mountains in the U.S. state of New York. It is located near the hamlet of Phoenicia, in the valley of Esopus Creek. At 2,740 feet (840 m) in elevation, it is well below the higher peaks of the region. Its slopes were a source of two major local products during the 19th century: hemlock bark, a source of tannin, and bluestone used in construction. Later it was the site of Tremper House, one of the Catskills' earliest railroad resorts. Henry Ward Beecher and Oscar Wilde were among the guests there.From the Wikipedia article “Mount Tremper”, licensed under CC BY-SA 4.0.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
Golden hour & blue hour by month
Summits catch first and last light — alpenglow can turn rock pink or orange minutes before sunrise and after sunset while valleys stay in shadow.

Local time (America/New York), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Mount Tremper, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.3 hours on a moonless night), and the core peaks around 19° above the southern horizon. Our light-pollution model puts the sky at about Bortle 4 (rural / suburban transition), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 20.83 mag/arcsec². Aurora needs roughly Kp 5.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 53% average cloud cover) and December as the cloudiest (78%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this mountain peak
- Long lenses compress ridgelines; shoot the peak from several miles away to make it look massive.
- Afternoon thunderstorms are common in summer at high elevations — plan summit hikes for early morning.
- Snow on the summit holds detail best when you expose for the highlights and lift shadows later.
- Alpenglow lasts only a few minutes; set up and focus beforehand.
- Clouds around the summit add drama — a clear blue sky is often the least interesting condition.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Early summer keeps snow on the peaks with green valleys below; autumn adds aspen or larch color in many ranges.
Suggested gear: Telephoto lens, Lightweight tripod, Warm layers, Microspikes in shoulder seasons. Work out exposures with the depth of field, ND filter and NPF rule calculators.
