Hiking
The Kīlauea Iki and Crater Rim Trail Loop offers an unparalleled journey from a dense rainforest into the heart of a volcanic crater. You'll descend through lush ʻōhiʻa trees and ferns, then traverse the solidified lava lake of Kīlauea Iki, an otherworldly landscape where steam rises from cracks and rocks can be warm to the touch. This moderate 6.4-mile (10.3 km) hike, with 711 feet (217 metres) of elevation gain, takes about 2 hours and 56 minutes, providing a dramatic contrast in scenery as you pass the Puʻu Puaʻi cinder cone.
For a smoother experience on this Kīlauea Iki trail, wear sturdy hiking shoes to navigate the rocky and uneven lava terrain. It's often recommended to hike the loop in a clockwise direction, as the ascent out of the crater on the west side is more gradual. Always check the national park's official site for current conditions, as volcanic activity can impact trail access.
What truly sets this route apart is the chance to walk directly across a crater floor that was once a molten lava lake, a powerful reminder of the 1959 eruption. The Kīlauea Iki geological features, like the

This loop typically takes about 2 to 3 hours to complete, covering a distance of approximately 6.4 miles (10.3 km).
What kind of terrain and scenery can I expect on this hike?
The trail offers a dramatic contrast. You'll hike through a lush, high-elevation rainforest with ʻōhiʻa trees and ferns, then descend into the otherworldly, barren landscape of the Kīlauea Iki crater floor, a solidified lava lake. Steam often issues from cracks in the earth, and you'll follow rock cairns across the lava.
Is the Kīlauea Iki and Crater Rim Trail Loop suitable for beginners?
This trail is generally rated as moderate to challenging due to significant elevation changes, including a 400-foot (122-meter) descent to the crater floor and subsequent ascent. The terrain can be steep, rocky, and uneven, with razor-sharp lava on the crater floor. It's best for hikers with some experience.
Where does the trail start and where can I park?
The main trailhead for this loop is located at the Kīlauea Iki Overlook parking lot within Hawaiʻi Volcanoes National Park. Another common starting point is near the Nāhuku (Thurston Lava Tube).
What unique geological features can I see on this trail?
You'll walk across the solidified lava lake of the Kīlauea Iki crater, formed during the 1959 eruption. Look for steam issuing from cracks in the earth and feel for warm rocks. You'll also see the Devastation Trail and the Nāhuku (Thurston Lava Tube), and pass the Kīlauea Iki East Overlook and Kīlauea Iki West Overlook.
Is there a recommended direction to hike the Kīlauea Iki and Crater Rim Trail Loop?
Many hikers recommend completing the loop in a clockwise direction. This makes the descent on the Nāhuku (Thurston Lava Tube) side more significant, while the ascent on the west side is generally more gradual.
What is the best time to hike the Kīlauea Iki and Crater Rim Trail Loop?
The trail is accessible year-round. However, be prepared for varying weather conditions, including hot, dry, wet, and windy weather. The crater floor has strong sun exposure, so early mornings or late afternoons might be more comfortable, especially on sunny days.

What wildlife might I see on this trail?
While hiking through the rainforest sections, especially along the Crater Rim Trail, you might spot native Hawaiian birds like the ʻapapane. The barren crater floor offers a different kind of natural wonder, with unique plant life adapting to the volcanic environment.
Does the Kīlauea Iki and Crater Rim Trail Loop connect with other trails?
Yes, the route incorporates sections of several well-known paths. You'll hike along portions of the Crater Rim Trail, the Kīlauea Iki Trail, the Byron Ledge Trail, and the Devastation Trail, as well as the Lava Tube Trail which leads to Nāhuku (Thurston Lava Tube).
