Hawai'i

Hawaii's walking is volcano and sea cliff — Mauna Kea and Haleakalā above, the Nā Pali coast and the Kalalau Trail below. Around the year 1100 Hawaiians climbed to the summit of Mauna Kea to quarry stone, because the basalt up there is denser than anything lower down. They carried up food, water and firewood and built shelters to keep the work going through the cold.

When to hike Hawai'i — trade winds, flash floods, and the month that changes everything

high10 src

Hawai'i has no bad month for hiking — but it has dangerous months. November through March brings Kona storms and flash floods. Hurricane season runs June through November. The trade winds that keep trails comfortable break down 10-15 times per year. The data on which months deliver the best conditions per island.

45+ people have drowned along the Kalalau corridor. Kīlauea erupted yesterday. The permit system just changed platforms. Maui is phasing out 7,000 short-term rentals. And the summit road on the highest peak voids your rental car insurance. Most Hawai'i hiking guides describe a paradise that requires zero preparation. They are describing a place that kills people who believe that.
