Kaluahonu — a volcano in Kauai County, Hawaii at about 131 m (430 ft) above sea level — is a rewarding subject for landscape photographers. It sits roughly 4.4 km (2.7 mi) ENE of Koloa.
Sunrise & sunset directions
At Kaluahonu the sunrise point swings a long way through the year: about 64° (ENE) at the June solstice and 115° (ESE) in late December. Sunset moves from 296° (WNW) in June to 245° (WSW) in December, and the midday sun climbs to 88° in summer but only 45° in winter.

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
Volcanic cones and lava fields have strong shapes that read well in side-light; dark basalt needs careful exposure.

Local time (Pacific/Honolulu), 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 Kaluahonu, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.7 hours on a moonless night), and the core peaks around 39° 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 ≈ 20.76 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 39% average cloud cover) and March as the cloudiest (54%). September is the warmest month and February the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this volcano
- Long lenses from 20–60 miles away make large stratovolcanoes dominate the horizon.
- Check local volcanic activity notices and area closures before visiting.
- Snow-capped volcanoes reflect alpenglow at sunrise — shoot from a lake or meadow for a reflection.
- Lava rock is sharp and unstable; stay on trails.
- Check road and trail conditions with the managing agency before you go.
Season: Summer for high trails; winter and spring for snowy cones viewed from below.
Suggested gear: Telephoto lens, Tripod, Sturdy boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
