Kilauea Iki Trail

Hiking the unique Kilauea Iki Trail in Hawaii Volcanoes Park 2023

One of the most unique and must do hikes in Big Island is the Kilauea Iki Trail. The Kilauea Iki trail is in Hawaii Volcanoes National Park on the Big Island of Hawaii.

This Kilauea Iki hike has it all! Walking through a lush tropical rainforest, walking inside a former lava crater lake (how cool is that!), having the chance to see an awesome huge lava tube, amazing views, all in a moderate 3 mile trail that is doable by most people.

I recently visited Big Island with my family and spent a week exploring the entire island. The Kilauea Iki trail was on my Hawaii hiking bucket list and it was one of the first things we did in our Big Island itinerary. Even before the beach!

Where is Kilauea Iki Trail

The Kilauea Iki trail is in Hawaii Volcanoes National Park in the Big Island of Hawaii.

Hawaii Volcanoes National park was established in 1916 and is home to two of the world’s most active volcanoes – Mauna Loa and Kilauea, and represents the sheer power of volcanoes to reshape land.

In 1959, the Kilauea Iki volcano erupted creating a gigantic crater filled with lava lake. Over the years the lava lake solidified and is now called the Kilauea Iki crater. In the Kilauea Iki Trail you will walk inside this crater of solidified lava lake. I cannot think of anything more mind blowing! Definitely a bucket list hike in any Big Island itinerary!

How to reach the Kilauea Iki Trail

Kilauea Iki trail is in Hawai’i Volcanoes National Park, which is in the southeast region of Big Island, Hawaii. Hawaii Volcanoes National Park entrance is on Hwy 11. Once past the entrance gate of Hawaii Volcanoes National Park, the Kilauea Iki Trailhead is only around 1.5 miles and takes about 5 minutes to drive.

Parking for Kilauea Iki Trail

There are three parking lots near Kilauea Iki Trail that can be used to park for this hike.

  1. Main parking lot at the Kilauea Iki Trailhead – This parking lot is right at the trailhead and the most busy. The trail starts from this parking lot. This is the most convenient place to park. If the parking lot is full, I recommend waiting for 10-15 minutes for someone to leave. We found a parking spot this way.
  2. Parking lot at Thurston Lava Tube – If the main parking lot is full you can try the parking lot at Thurston Lava tube. To reach this parking continue further down the Crater Rim drive and you will reach this smaller parking lot in 0.4 miles.
  3. Parking lot at Kilauea Visitor Center – The last alternative is to park at the Kilauea Visitor Center which is 1.5 miles away and is a bit of a walk to reach the trailhead.

How to hike the Kilauea Iki Trail

The Kilauea Iki Trail can be divided into four parts. Climbing down via the Crater Rim Trail, walking across the crater floor, climbing back up through the rainforest, visiting the Thurston Lava Tube and finally making your way back to the Kilauea Iki Trailhead (Assuming you have parked there).

Which direction should you hike the Kilauea Iki Trail?

You can do the Kilauea Iki trail clockwise or counterclockwise from the Kilauea Iki trailhead. I recommend doing this hike counter-clockwise i.e. start at the right side entrance from the parking lot.

Here’s why you should do this hike counterclockwise – If you start counter clockwise your return climb will be through a shaded lush rainforest which is great for the climb part of this hike. Also at the end of the climb is the Thurston lava tube and you can cool off in the lava cave. The rest of this hike is described in this counter clock direction.

Crater Rim Trail – First part of Kilauea Iki Trail loop

In the first part of the Kilauea Iki Trail loop you go down a forest path via the Crater Rim Trail. This part is easy as it is all downhill with some flat areas. The downhill grade is gradual making it a pleasant walk.

There are a couple of overlooks here with rail guards to look down at the crater below. You will see a faint line in the middle of the crater which is the trail path on which you will be walking once you reach down. If you see closely you will see people walking on that path. They look really small from up here.

The Crater Rim trail towards the end descends down into the crater. There are some steps here and some uneven grades but nothing too difficult.

Walking inside the Kilauea Iki Crater – Second part of Kilauea Iki Trail loop

Once you are down on the crater floor you start your journey across the crater floor. The crater floor is uneven and broken and it is very important here to stay on the trail path.

You will see huge broken lava rocks and uneven surfaces around you. It is surreal to think that this was a molten lava lake less than 75 years ago.

The walk across the crater floor is around a mile. If it’s a sunny day this is where you might need water as there is no shade on this path.

You might see native trees and flower blooms growing on the lava rocks and crater floor. Kids were climbing on the broken lava rocks.

Puupuai is a giant cinder cone that you can see on one side of the crater. Once you reach the other end of the crater You will find the path to go up the crater.

You will see the Ohia native tree growing in the lava rocks. The tree has some showy red flowers that look so pretty against the black lava rocks landscape.

Climb up through a lush rainforest – Third part of Kilauea Iki trail

If you did this hike counter clockwise, the way back up from the crater passes through an lush rainforest. It is shaded and cool and the elevation here doesn’t feel that bad. We were easily able to climb back up admiring the various trees and tropical plants.

There are a few clearings here to glance at the crater that you just walked presenting a different angle for photos. As we were walking through the rain forest fog started to set in and the crater views were not that clear.

Visit the Nahuku Thurston Lava Tube – Optional fourth part of Kilauea Iki trail

Once you reach the top of Crater Rim drive you will see the Thurston lava tube right across the street from the parking lot. I highly recommend you make time to visit this 500 year old lava tube as it is huge and amazing. It is one of the biggest lava caves I have seen till date.

The total walk inside the lava cave is around less than half a mile and easily doable by all. There are no steps in the lava tube. The cooler temperature inside the lava tube feels great after the climb back up from the crater.

The lava tube has lights inside during the day from 8 AM to 8 PM. There might still be some dark corners for which you might need a headlamp or phone light. There might be some low ceilings for which you might need to watch your head. There also might be some water puddles on the floor of the cave.

Making your way back to the Kilauea Iki Trailhead

After visiting the Thurston Lava Tube, you will notice a trail path across the parking lot that takes you back to the Kilauea Iki Trailhead. This trail path is mostly flat and less than half a mile.

There is an overlook here to take a final peak at the Kilauea Iki crater. After a short walk you will reach the Kilauea Iki Trailhead. What a rewarding hike!
