Pololū Valley Trail
ValleyBlack SandScenic Overlook Moderate
A short but steep descent from a jaw-dropping overlook into the floor of Pololū Valley, where a black-sand beach meets the crashing North Kohala surf. The lookout alone is worth the drive — the hike down is a bonus.
Tip The 10-minute parking at the lookout is strictly enforced. Hikers should park along the road. The trail is muddy after rain — bring traction.
End of Akoni Pule Highway (Hwy 270), past Hāwī and Kapaʻau
Kīlauea Iki Trail
VolcanicRainforestNational Park Moderate
One of the great walks in the national park system. You descend through native ʻōhiʻa rainforest into the crater of Kīlauea Iki, then cross the solidified lava lake — still steaming from vents below your feet. Surreal doesn’t begin to cover it.
Tip Park entrance is $30/vehicle (7-day pass). Note: the Kīlauea Visitor Center is closed for renovation through late 2026 — use the Welcome Center at Kīlauea Military Camp instead.
Captain Cook Monument Trail (Kaʻawaloa Trail)
Bay AccessSnorkelingHistorical Challenging
A relentless descent through dry kiawe forest to the obelisk marking the spot where Captain Cook was killed in 1779. The reward: Kealakekua Bay’s extraordinary snorkeling, with spinner dolphins, coral gardens, and water so clear you can see the bottom at 40 feet.
Tip The hike back is brutal — 1,300 feet of elevation gain in full sun. Start at dawn, bring 3+ liters of water, and wear sun protection. Only 12 parking spots at the trailhead.
Puʻu Waʻawaʻa Cinder Cone Trail
Cinder ConePanoramic ViewsNative Forest Moderate
A fascinating climb up an ancient cinder cone on the slopes of Hualālai, with panoramic views stretching from the Kohala mountains to the Kona coast. The surrounding forest reserve shelters rare native plants found nowhere else on Earth.
Tip Free. Park at the automatic gate and walk south along Vulcanite Road 1.5 miles to the cone trail.
Mauna Kea Summit Hike
SummitAlpineStargazing Very Challenging
At nearly 14,000 feet, the summit of Mauna Kea is the highest point in the Pacific — and the hike from the Visitor Information Station is one of the most challenging day hikes in Hawaiʻi. Thin air, volcanic scree, and alpine desert make this a true mountain experience.
Tip Acclimatize at the Visitor Information Station (9,200 ft) for at least 30 minutes before ascending. Not recommended for children, pregnant women, or those with heart or respiratory conditions.
