Hiking
The Kīlauea Iki Trail is an extraordinary hiking experience that transports you from a vibrant rainforest into the heart of a volcanic crater. This 3.6-mile (5.8 km) loop takes you across a solidified lava lake, a surreal landscape dotted with cracks and steaming vents, before ascending back through lush vegetation. You'll encounter native Hawaiian plants like ʻŌhiʻa and Hāpuʻu as you descend into the crater, then navigate the barren, otherworldly floor, guided by rock cairns.
Planning your visit to this easy trail, which typically takes about 1 hour and 42 minutes to complete, is straightforward. The trailhead is at the Kīlauea Iki Overlook within Hawaiʻi Volcanoes National Park, but parking can be limited, so arriving early is a good idea. With 545 feet (166 metres) of elevation gain, the trail has some steep sections; hiking clockwise is recommended for a more gradual ascent out of the crater. Always wear sturdy hiking shoes to protect against the sharp lava rock.
This trail is a geological marvel, offering a tangible connection to the powerful 1959 eruption where lava fountains soared incredibly high. Walking across the crater floor, you're directly on the remnants of that event, observing unique features like solidified lava and steaming ground. The dramatic contrast between the dense, humid rainforest and the dry, volcanic crater floor makes this one of the most captivating and educational hikes in the park.

Frequently Asked Questions
How long does it typically take to hike the Kīlauea Iki Trail?
The Kīlauea Iki Trail is a 5.3 km (3.3-mile) loop. Most hikers complete it in approximately 2 to 3 hours, depending on their pace and how much time they spend observing the unique volcanic landscape.
What is the difficulty level of this hike?
This trail is generally considered moderate to challenging. The main challenge comes from the steep 122-meter (400-foot) descent into and ascent out of the crater. Hiking across the crater floor requires careful footing due to uneven lava rock and fissures. While komoot rates it as 'easy' based on overall stats, the varied terrain and elevation changes make it more demanding than a typical easy hike.
Where is the trailhead and parking for the Kīlauea Iki Trail?
The trailhead for the Kīlauea Iki Trail is located at the Kīlauea Iki Overlook within Hawaiʻi Volcanoes National Park. There is a dedicated parking lot at the overlook.
Are dogs allowed on the Kīlauea Iki Trail?
No, pets are generally not permitted on trails within Hawaiʻi Volcanoes National Park, including the Kīlauea Iki Trail, to protect wildlife and natural resources. Service animals are an exception.
Do I need to pay an entrance fee or get a permit to hike this trail?
Yes, the Kīlauea Iki Trail is located within Hawaiʻi Volcanoes National Park, so an entrance fee is required to access the park. You can find current fee information on the official NPS website. No special permits are needed for day hiking the Kīlauea Iki Trail itself.
What is the best time of year to hike the Kīlauea Iki Trail?
The trail can be hiked year-round. However, conditions can vary, including hot, dry, wet, or windy weather. The crater floor is exposed to the sun, so mornings are often preferred to avoid the midday heat. Be prepared for rain at any time, especially in the rainforest sections.
What kind of terrain can I expect on the Kīlauea Iki Trail?
The terrain is incredibly diverse. You'll start by descending through a lush, wet rainforest with roots and rocks, which can be muddy. Once on the crater floor, you'll walk across a solidified lava lake, which is uneven, rocky, and features deep earth cracks and fissures. You'll follow rock cairns (ahu) across this otherworldly surface. The return ascent is steep but shorter, leading back into the rainforest.
What are the main points of interest along the route?
This trail offers a striking contrast of scenery. You'll hike through a vibrant Fern Rainforest, enjoy views from the Kīlauea Iki West Overlook, and experience walking directly across the Kīlauea Iki Crater Trail, a solidified lava lake. You can also see volcanic steam rising from cracks and the vent from the 1959 eruption. The nearby Nāhuku (Thurston Lava Tube) is also a popular stop.
Does the trail intersect with other paths?
Yes, the route also passes through sections of the Crater Rim Trail, Kīlauea Iki Trail, Lava Tube Trail, Thurston Lava Tube (Nāhuku), and Byron Ledge Trail.
What is an insider tip for hiking the Kīlauea Iki Trail?
Many hikers recommend doing the loop clockwise. This makes the ascent out of the crater slightly easier, as the steeper section is shorter. It's also advisable to start early to avoid crowds and the midday sun on the exposed crater floor.
What should I bring for a hike on this trail?
Given the varied terrain and exposure, essential items include sturdy hiking shoes, plenty of water, sun protection (hat, sunscreen, sunglasses), and rain gear. The weather can change quickly, and parts of the crater floor are completely exposed.
