Located in Westchester County, New York, Untermyer Park is a botanical garden. The nearest town is Hastings-on-Hudson, about 3.2 km (2.0 mi) away (Untermyer Park lies SSW of town). It is listed on the National Register of Historic Places.
Untermyer Park and Gardens is a historic 43-acre (17 ha) city public park, located in Yonkers, New York in Westchester County, just north of New York City. The park is a remnant of Samuel Untermyer's 150-acre (61 ha) estate "Greystone". Situated on the steep land arising from the eastern bank of the Hudson River to the bluff on top of it, the park's principal feature is the Walled Garden, inspired by ancient Indo-Persian gardens, in which are found a small Grecian-style open-air amphitheater with two opposing sphinxes crouching atop paired Ionic columns; a classical pavilion; a stoa and loggias; and a circular, open-air tempietto called the Temple of the Sky. A long staircase leads from the Walled Garden to an Overlook with views of the river and the Palisades.From the Wikipedia article “Untermyer Park and Gardens”, licensed under CC BY-SA 4.0.

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 Untermyer Park, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° above the southern horizon. Our light-pollution model puts the sky at about Bortle 9 (inner-city sky), 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: 9 Bortle 9 — Inner-city sky. Only the Moon, planets and a few bright stars are visible. Modeled zenith brightness ≈ 17.86 mag/arcsec². Aurora needs roughly Kp 6.0+ 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 48% average cloud cover) and December as the cloudiest (70%). 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 botanical garden
- Seasonal exhibits (orchids, tulips, cherry blossoms) draw crowds — arrive at opening.
- Kaleidoscopic and abstract images are great for flower close-ups — try the online kaleidoscope tool.
- A macro lens or close-up filter opens a world of detail — try a shallow aperture against a soft background.
- Many gardens restrict tripods or charge for photography; check the rules before you go.
- Backlit petals glow; position yourself so the sun is behind the flower.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Spring bulbs and blossoms, summer perennials and autumn color; glasshouses offer winter subjects.
Suggested gear: Macro lens, Diffuser, Small reflector. Work out exposures with the depth of field, ND filter and NPF rule calculators.
