Kilauea Iki Trail, the best Big Island hike – NOW FULLY REOPENED

One of the most memorable experiences during our recent Hawaii island hopping adventure, was hiking through the crater of an active volcano. And active proved to be quite accurate, since the 2018 Kilauea eruption took place just 2 to 3 weeks after our visit. Hiking the Kilauea Iki trail is an epic experience, one that should rank high up on your Hawaii bucket list. And the best news is that the Kilauea Iki trail has been fully reopened since 21 September 2019. So, what are you waiting for?

You’ll find everything you ever wanted to know about this spectacular Big Island hike in this article. We’ve added plenty of pictures of the hike too, mile by mile, so you’ll know exactly what to expect when hiking the Kilauea Iki trail.

Where to find the Kilauea Iki trail + current situation

The Kilauea volcano is located on the Big Island of Hawaii. It’s the youngest of Hawaiian islands and packed with volcanoes. Learn more about its volcanoes our article on the most surprising facts about Hawaii.
One of the reasons we opted for this island as our third stop while island hopping Hawaii, is that it is home to Hawaii Volcanoes National Park. This World Heritage Site and designated International Biosphere Reserve is home to not one but two active volcanoes: the Mauna Loa, world’s largest volcano, and the infamous Kilauea, which erupted in the spring of 2018.

We researched the park’s various hikes and decided to go for the The Kilauea Iki trail, a loop trail leading through the northern rim’s lush rain forest to the floor of the steaming but solidified lava lake of the Kilauea Iki (little Kilauea) crater. It’s one of the most popular Volcanoes National Park hikes and known to be one of the best Big Island hikes.

The Kilauea Iki trail was temporarily closed after the volcano’s eruption. Part of the trail was reopened mid-April 2019. It’s been fully reopenend since 21 September 2019.

Facts and figures about the crater and the trail

About the Kilauea Iki crater

This Kilauea Iki (little Kilauea) crater is the side crater to the Kilauea’s main crater. In 1959, it was the scene of an eruption with lava fountains up to 1,900 ft (or 580 m) high. The walls around the Kilauea Iki crater are nearly vertical because it’s a pit crater: a sunken surface with vertical walls, like an inverted cone.

About the Kilauea Iki trail

  • Distance: 4 miles (or 6.4 km).
  • Time: 2 to 3 hours. We’re no experienced hikers and it took us 2 hours and 45 minutes to complete the trail with 2 kids in town (8 and 6 years old at the time).
  • Difficulty: Medium. Some parts are pretty easy but the part where you transition from rain forest to crater lake is pretty steep and rocky.
  • Elevation: The Kilauea Iki trail begines at 3,874 feet (or 1180 m) above sea level. The decent and ascent go up to 400 feet (or 122 m).

You start the Kilauea Iki hike through lush rain forest along the crater rim.

Several overlooks would have given us an idea of what to expect further down the trail but the fog decided differently.

The path changes and gets more rocky. This is the area where molton rock has spattered after the 1959 eruption. Soon the trail will start descending.

This is the most difficult part of the Kilauea Iki trail because of the many large boulders that make the descent pretty challenging. These rocks fell of the cliffs during several powerful earthquakes.

The path is marked by stacked rocks. It’s still a bit uncomfortable to walk but you can see that this is the last rough episode. The Lehua blossom on the Ohia trees adds colour to the black lava. This strong tree, native to Hawaii, roots in the lava cracks when windblown seeds mix with water and nutrients.

As the Kilauea Iki trail becomes flatter, the lava starts to shw some color too. Oxidizing volcanic gases transform the iron-rich lava minerals in different shades. You can tell how proud the girls are for not having given up during the challenging part.

The trail is completely flat, apart from some big cracks. The crater floor is still steaming, several steam vents can be spotted. It’s rainwater that comes in touch with the hot rocks below the surface and vaporizes. When you touch the ground you can feel the heat coming through. Spectacular!

This is where the ascent to the rainforest begins but it’s also a good location to take a final look over the crater floor. It’s not nearly as rocky here as it is on the opposite side of the crater, where we descended. The trail is actually pretty easy in this part and, well, a bit boring.

You’ll find the Thurston Lava Tube (Nāhuku) ride across the road. NOTE: This tube has not yet been reopened. When you’re ready, take the last half mile (0.8 km) of the trail to the parking lot.

What makes this the best Big Island hike

In our opinion, three things make the Kilauea Iki trail the most spectacular Big Island hike:

  1. The diverse landscape: Rainforest vs lava and the naked lava vs the blossoming Ohia tree.
  2. The spectacle: Seeing the steam coming through the vents and feeling the heat coming from the ground makes you realize how active this volcano still is. You can literally feel the force of nature.
  3. The well-marked path: You can’t get lost so you can take it all in without having to trace your steps.

Cost & how to reach the Kilauea Iki trail head

  • Drive up to Hawaii Volcanoes National Park and pay the entrance fee of $25 per car. If you plan on visiting the other Hawaiian National Parks (Haleakala National Park and Pu‘uhonua o Hōnaunau National Historical Park) within the year, you could also go for the Tri-Park Pass at $50.
  • Head towards the entrance and make a right on to Crater Rim Drive. You’ll find the Kilauea Iki parking lot about 2 miles (3.2 km) down the road.
  • You can choose to hike the Kilauea Iki trail in either direction.

It’s very well doable to visit Hawaii Volcanoes National Park on your own. However, if you consider joining a guided tour, here are some excursion options.

How to prepare for the Kilauea Iki Trail

  • Form the entrance, before heading to the Kilauea Iki trail head, drive down to the Visitors Center. Why make a stop there? Kilauea is an active volcano and the conditions are always subject to change. The same goes for the wind, moving toxic sulfur dioxide and volcanic gases to different areas of the park. So, make sure to check the latest conditions before starting any Kilauea volcano hike.
  • Since you’re high above sea level, the weather is pretty unpredictable but generally a bit on the cool side. Bring a raincoat or poncho and some sunscreen too. Our day started out rainy and foggy but after an hour the sky cleared and the temperatures went up.
  • The terrain is rocky and steep so make sure to wear sturdy shoes.
  • A map is not really required since the Kilauea Iki trail path is well-marked. On the crater floor the aha (stacked rocks) mark the trail. This guide is pretty interesting since it points out some features you might otherwise easily miss.

Best time of day to hike the Kilauea Iki Trail

Temparature-wise, Big Island hikes are usually best taken in the morning. However, since the Kilauea rises high above sea level, you could get away with an afternoon walk too. Doing so, you will also avoid the foggy conditions that are more common in the morning.

We started hiking the Kilauea Iki trail around noon and the fog only cleared around 1PM. It would have taken too long to wait for twilight. Still, we could see some glowing lava in the Halema’uma’u crater. Look closely at this picture and you will see the orange glow in the crater.

Spiritual importance of the Kilauea volcano in Hawaiian culture

In Hawaiian culture, the Kilauea volcano, and more specific the Halemaʻumaʻu crater, is said to be the home of Pele, the goddess of fire. Many native Hawaiians still believe that lava is her physical embodiment.

That spiritual belief is still very much alive. We saw a young Hawaiian man patiently waiting in line at the viewpoint next to the Jagger museum’s parking lot. He was holding a kind of box made out of palm leaves. I approached him and asked him, respectfully, if this was an offering to Pele. He confirmed and said it was a food item made from macadamia nut. I could see he was bothered by the other visitors standing on some rocks to be able to take a better picture of the lava. In Hawaiian culture, it’s considered very disrespectful to move rocks, let alone stand on them. Consider this and be respectful when visiting mount Kilauea. Have another look at the previous photo where you can see the offerings on the ground (one of which is a flower).

How to combine the Kilauea Iki trail

There are plenty of options to combine this hike. Our favorites would be:

  • Driving the Chain of Craters Road, 18.8 miles long, which is said to be spectacular.
  • Having a break at Punaluʻu black sand beach, just half an hour drive from Volcanoes NP. You’ll find some turtles there too.
  • Still some energy left? Then how about a hike to the intriguing Papakolea green sand beach?

Hotels near Hawaii Volcanoes National Park

Volcano Village is a popular holiday village close to Hawaii Volcanoes National Park and amidst the rain forest. However, most accommodations here are pretty basic and didn’t really appeal to us. And since Hilo is actually just a 40 minute drive away, we chose to keep the Grand Naniloa Hotel as our travel base for Hawaii Volcanoes National Park too. It’s the best hotel around on the island’s east side and it offers gorgeous views over Hilo bay.
