Puʻu Huluhulu is a volcano in Hawaii County, Hawaii. It sits roughly 37 km (23 mi) NW of Volcano.
Puʻu Huluhulu is a volcanic cone located near the center of the Island of Hawaii in the State of Hawaii. It is located on the southern side of Hawaii Route 200 (Daniel K. Inouye Highway, also known locally as Saddle Road), directly across from the highway's intersection with the Mauna Kea Access Road. Puʻu Huluhulu is Hawaiian for hairy hill (puʻu=hill and huluhulu=hairy). The cone is a kīpuka, which is an older volcanic hill covered with vegetation, surrounded by the younger lava flow. The hill is located on Hawaii Route 200 and is a native tree sanctuary and a nature trail. Beginning in July 2019, various groups opposed to the Thirty Meter Telescope gathered at Puʻu Huluhulu to block Mauna Kea Access Road and temporarily stop its construction, despite the Hawaii Supreme Court's ruling to allow construction to move forward.From the Wikipedia article “Puʻu Huluhulu”, licensed under CC BY-SA 4.0.

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.

Milky Way & night sky
From Puʻu Huluhulu, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.8 hours on a moonless night), and the core peaks around 41° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.85 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show January as the clearest month (about 50% average cloud cover) and March as the cloudiest (62%). August 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
- 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.
- Long lenses from 20–60 miles away make large stratovolcanoes dominate the horizon.
- 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.
