Kīlauea Iki and Crater Rim Trail

This moderate hike usually takes around 3 hours and 20 minutes to complete the full loop. However, allow extra time to enjoy the unique scenery, take photos, and explore the various viewpoints.

The trail offers a dramatic contrast in terrain. You'll start by descending through a lush, dense rainforest, which can be muddy and slippery, especially after rain. It then transitions onto the solidified lava lake floor of the Kīlauea Iki crater, which is barren, dry, and uneven with sharp lava rock. Steam often rises from cracks in the crater floor. The ascent back out of the crater is more gradual, leading you back into the rainforest along the rim.

This trail is packed with unique sights. You'll walk across the Kīlauea Iki Crater Trail, a solidified lava lake, and pass by Kūkamāhuākea (Steam Vents). Other notable spots include the Kīlauea Caldera North Overlook and the Haʻakulamanu (Sulphur Banks) Overlook. The route also connects to the popular Nāhuku (Thurston Lava Tube).

The trail is rated as moderate to challenging due to steep, rocky sections and uneven, sharp lava terrain. While the experience is incredible, it might be strenuous for very young children or those new to hiking. Hikers should be prepared for a 400-foot descent and ascent. It's best for families with older children who are accustomed to hiking on varied terrain.

Parking is available near the Kīlauea Visitor Center within Hawaiʻi Volcanoes National Park. The trailhead for Kīlauea Iki is typically accessed from the parking lot across from the Thurston Lava Tube (Nāhuku). Parking can fill up quickly, especially during peak hours.

Hawaiʻi Volcanoes National Park is open year-round, and the trail can be hiked in any season. However, weather conditions can vary greatly. The dry season (April to October) generally offers sunnier and drier conditions, while the wet season (November to March) can bring more rain, making rainforest sections muddy and slippery. Early mornings are often best to avoid crowds and afternoon heat or rain.

No, dogs are generally not allowed on most trails within Hawaiʻi Volcanoes National Park, including the Kīlauea Iki and Crater Rim Trail, to protect wildlife and natural resources. There are limited pet-friendly areas within the park, such as paved roads and parking lots, but not on this specific hiking trail.

Given the varied conditions, it's wise to pack layers of clothing, sturdy closed-toe hiking shoes with good grip, a hat, and sunscreen. Bring plenty of water and snacks, as there are no services directly on the trail. Rain gear is also recommended, as weather can change quickly. A flashlight or headlamp is useful if you plan to visit the nearby Nāhuku (Thurston Lava Tube).

Yes, the route primarily follows sections of the Crater Rim Trail and the Kīlauea Iki Trail. It also briefly connects with the Lava Tube Trail, which leads to Nāhuku (Thurston Lava Tube).

Many hikers find that hiking the loop clockwise offers a more gradual ascent out of the crater. If you go counter-clockwise, you'll experience a steeper descent into the crater and a more spread-out climb out. Both directions offer incredible views, so choose based on your preference for steepness.
