Mount Tom is a mountain peak in Hampden County, Massachusetts at about 363 m (1,191 ft) above sea level. The nearest town is Easthampton, about 3.3 km (2.1 mi) away (Mount Tom lies SSE of town).
Mount Tom, 1,202 feet (366 m), is a steep, rugged traprock mountain peak on the west bank of the Connecticut River 4.5 miles (7 km) northwest of downtown Holyoke, Massachusetts. The mountain is the southernmost and highest peak of the Mount Tom Range and the highest traprock peak of the 100-mile (160 km) long Metacomet Ridge. A popular outdoor recreation resource, the mountain is known for its continuous line of cliffs and talus slopes visible from the south and west, its dramatic 1,100-foot (340 m) rise over the surrounding Connecticut River Valley, and its rare plant communities and microclimate ecosystems. Located in Easthampton and Holyoke, Mount Tom is traversed by the 110-mile (180 km) Metacomet-Monadnock Trail and is the transmitter location for three Springfield–Holyoke television stations: WGBY, WGGB, and WSHM-LD, and for radio stations WHYN-FM and WWEI.

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.

Milky Way & night sky
From Mount Tom, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.2 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 7 (suburban / urban transition), so expect visible sky glow; drive away from towns for better results.

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: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.77 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 51% average cloud cover) and December as the cloudiest (68%). 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
- 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.
- Photograph the peak from a lake, meadow or ridge at sunrise when the face that looks east lights up first.
- Long lenses compress ridgelines; shoot the peak from several miles away to make it look massive.
- Check road and trail conditions with the managing agency before you go.
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.
