Things to do nearKīlauea Iki Crater
Kīlauea Iki Crater on Hawaiʻi Island is a hardened lava lake within Hawaiʻi Volcanoes National Park, offering dramatic geology, sweeping caldera views, and rare native rainforest.
Kīlauea Iki Crater sits within Hawaiʻi Volcanoes National Park on the Big Island and last erupted in 1959, when a lava fountain reached over 1,900 feet, filling the crater with a lake of molten rock roughly 400 feet deep. That eruption lasted weeks and reshaped the landscape permanently.
Today visitors descend 400 feet through native rainforest on the 4-mile loop trail before stepping onto the crater floor itself. Cairns mark the route across the hardened lava, and fumaroles occasionally release wisps of steam, reminding you that the ground remains geologically active beneath the surface.
The surrounding forest shelters native plants including ʻōhiʻa lehua and tree ferns, and the contrast between the lush green canopy and the stark black lava below defines the hike visually. Rangers at the nearby Kīlauea Visitor Center offer geology talks and trail updates worth seeking out before you set off.
Kīlauea Iki Crater stands as one of the most accessible and visceral encounters with volcanic geology anywhere in the United States, making it a compelling destination for anyone drawn to the raw, living landscape of Hawaiʻi.
7-day forecast
Chance of rainTips for visiting Kīlauea Iki Crater
Start the Kīlauea Iki Trail early in the morning to avoid midday heat and to catch the crater floor in soft light with fewer crowds.
Wear sturdy closed-toe shoes with good grip, as the lava surface is uneven and can be sharp in places.
Bring a light rain jacket even on sunny days, since the crater rim passes through rainforest where showers arrive quickly.
Look for ʻapapane and other native honeycreepers in the ʻōhiʻa trees along the rim section of the trail.
Stop at the Thurston Lava Tube, located just minutes from the trailhead, to extend your visit with another distinct volcanic landscape.
