Adventures in the Wild
From volcanic trails to pristine night skies
Written by a Local Expert
Leilani AkoKahuku Unit of Hawaii Volcanoes National Park
Far from Kilauea's glowing crater lies the Kahuku Unit. This 116,000-acre expanse shows a different volcano experience. Rolling pastures, historic ranchlands, and recovering native forests tell stories of time and transformation.
The 1868 lava flows are no longer barren rock. They're integrated into grassy meadows and ranch roads. Here you see how earth heals over time.
Kahuku is open Thursday through Sunday, 8 AM to 4 PM. It's closed Monday through Wednesday. Entry is included with your Hawaii Volcanoes National Park pass. No potable water is available. Bring your own.
🌳 Protecting Native Forests
To prevent Rapid ʻŌhiʻa Death, use the decontamination station before accessing upper trails. This fungal disease devastates native forests. Following protocols protects our trees.
Free guided hikes and orientations are often offered. Check the official park calendar for schedules.
Three Trails, Three Experiences
🚴 Palm Trail (2.6 miles loop)
Perfect for hiking or biking. It crosses scenic pastures with volcanic features and offers panoramic coast views. Great for families and beginners.
🌲 Puʻu o Lokuana Trail (2 miles)
Follows historic ranch roads. You'll see impressive lava tree molds from the 1868 eruption. These are casts left when lava flowed around living trees.
⛰️ Pit Crater Trail (2.4 miles)
For experienced hikers. Demanding climb with significant elevation gain leads to a massive pit crater rim. An untouched Hawaiian rainforest lives within the steep walls.

Adventures in the Wild
Coastal Adventures and Underground Worlds
The Ala Kahakai National Historic Trail connects ancient coastal communities. A rewarding section runs from Punaluu toward Kawa Bay. This route follows old government roads across lava fields. You'll pass sacred sites including the Kaʻieʻie and Keʻekū heiau.
⚠️ Coastal Safety Requirements
Sea cliffs erode continuously and can collapse without warning. Stay well back from edges.
Sharp lava rock covers much of the ground. Sturdy, closed-toe shoes prevent serious cuts.
Large, unpredictable waves can sweep over ledges. Never turn your back on the ocean.
Kula Kai Caverns: Journey Underground
For underground adventure, visit Kula Kai Caverns in Ocean View. This thousand-year-old lava tube system offers guided tours through volcanic plumbing. Unlike sea caves carved by water, lava tubes are conduits formed by flowing magma. You'll climb down ladders and learn unique geology.
🕳️ Lava Tube Formation
Learn how flowing magma creates these natural tunnels and the unique geology that makes each cave system different.

Stargazing on the Southern Frontier
When night falls, Kau reveals breathtaking skies. Remote location and minimal development create virtually no light pollution. This makes it one of Hawaii's premier stargazing locations.
Light pollution maps rank Kau in the darkest categories. The Milky Way appears not as a faint cloud, but as a brilliant, textured river of stars.
Manuka State Wayside Park sits just off Highway 11. It's designated as a Bortle 1 site, the darkest possible classification. Accessibility and pristine skies make it ideal for telescopes or simple star watching.
Prime Stargazing Locations
🌌 Manuka State Wayside
Bortle 1 designation (darkest skies). Easy highway access with parking and some facilities.
🌠 Ka Lae Parking Areas
Dramatic foregrounds for stargazing. The celestial sphere arches over the vast, dark Pacific.
⭐ Mauna Ulu Lookout
Higher elevations in Hawaii Volcanoes National Park offer phenomenal dark-sky viewing away from any town lights.
🔭 Highway 11 Pullouts
Multiple safe pullout areas along the highway offer excellent sky access and easy vehicle access.
💡 Stargazing Success Tips
Plan around a new moon to eliminate moonlight and see the faintest stars and galaxies.
Bring a flashlight with red filter to protect night vision while reading star charts or setting up equipment.
Pack warm layers. Wind at Ka Lae and elevation elsewhere make for chilly evenings, even in tropical Hawaii.
Under Kau's pristine skies, you'll see the universe as our ancestors did. The Milky Way stretches across the heavens like a cosmic river. Shooting stars streak through the darkness. This is where earth meets cosmos in perfect, humbling silence.
🔭 What to Bring
- Red-filtered flashlight
- Warm blankets/layers
- Comfortable chair
- Star chart/app
- Binoculars/telescope
