Twin Falls is a waterfall in Jerome County, Idaho at about 1,072 m (3,517 ft) above sea level. It sits roughly 6.2 km (3.9 mi) N of Kimberly.
Twin Falls is a waterfall on the Snake River in the Snake River Canyon of South Central Idaho on border of Twin Falls and Jerome counties. The name refers to the two parallel falls that existed prior to dam construction, of which only the north (river right) channel remains. The city of Twin Falls, located a few miles downstream, is named for the falls. Twin Falls is located downstream of Milner Dam and upstream of Shoshone Falls and Pillar Falls.From the Wikipedia article “Twin Falls (Idaho)”, 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
Waterfalls photograph best in soft, even light: overcast days, deep shade, or the hour after sunrise before direct sun hits the water. Bright sun on white water blows highlights and adds harsh contrast.

Local time (America/Boise), 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 Twin Falls, 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 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 ≈ 20.65 mag/arcsec². Aurora needs roughly Kp 6.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 32% average cloud cover) and December as the cloudiest (72%). 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 waterfall
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- A 3-stop ND filter lets you use slow shutter speeds even when the light is bright.
- Shoot a vertical and a horizontal frame; tall falls often work better in portrait orientation.
- Use 1/4 to 1 second for a silky look; 1/500 s or faster freezes individual drops.
- A circular polarizer cuts glare on wet rocks and leaves and deepens greens — rotate it while watching the rocks, not the sky.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. Work out exposures with the depth of field, ND filter and NPF rule calculators.
