Overview: The volcanic activity that created the Hawaiian island chain hasn't yet finished working on what's know as the 'Big Island' called Hawaii. If you need evidence, look no further than the lava flows and gas eruptions that spill from the Kilauea volcano located on the south-east side of the Big Island.

You'll find Kilauea at Volcanoes National Park where there's plenty to see even without stepping far from your vehicle. However, being hikers we'd suggest leaving your car by Thurston Lava Tube and setting out on an eight-and-a-half mile trek into the Kilauea pit crater itself, along the huge expanses of lava and taking in the Halema'uma'u crater-within-a-crater on the way.

There's something other-worldly about walking across a desolate 4-mile wide crater over huge expanses of strangely patterned lava flows. Steam and sulfuric gases venting into the air are stark reminders that you're standing on top of an immense volcano, but the sight of flowers and other vegetation rising out of the cracks reassure you that the lava you're standing on is decades old.

Elevation gain:
• 800ft (from 3,500 - 4,100ft)

Tips:
• Volcanoes National Park operates a day-use fee.
• Check the park's website for details on any temporary closures of park trails due to volcanic activity.

Alternatives:
• Consider the short walk through Thurston Lava Tubes located at the trailhead of this hike.
• There's a shorter (5.2 mile) out-and-back route to Halema'uma'u Crater which begins and ends at the Kilauea Visitor Center.


Points of Interest

Trailhead

The Thurston Lava Tubes parking lot is an ideal location to begin this hike, and if you have enough time we recommend a detour to the lava tubes across the road also.

Walk into lush dense woodland to begin your hike of the craters. Our route initially traces the Northern flanks of the smaller of the two Kilauea craters.

Kilauea Iki Crater

The trail that skirts the rim of the Kilauea Iki Crater rewards with views of this surreal bowl-like feature.

The lava exposed at the surface here is from around 1954, meaning there has been time for half a century worth of hiking boots to define a trail across it's surface which should be plain to see. This will be part of the last leg of our hike today.

Leave the Crater Rim Trail behind and downhill towards the Kilauea Caldera proper.

[JCT] Take a right turn

At this T-junction bear right and take a few more steps onto the lava surface inside the caldera of one of the most active volcanoes on the planet.

[JCT] Turn left onto Halema'uma'u Trail

At this point the route should be quite obvious despite the fact that you're walking on solid rock. Head out into the wide desolate expanse of the lava beds and across a lava flow that was created in 1974.

Lava Flows before 1924

Spot the contrast in terrain here? Up until now you've been hiking on a lava flow that was formed in 1974, but now you're on a much older pre-1924 lava bed.

Here you'll begin to see increasing evidence of life taking hold again with occasional flourishes of green and even the occasional flower!

[JCT] with Byron Ledge Trail

Make a note of this point, which is where we'll be departing from the trail on our return from our side-trip to Halema'uma'u Crater.

Halema'uma'u Crater

Local lore tells us that Kilauea is the home of the legendary volcano goddess called Pele. Offerings are left by the side of Halema'uma'u Crater to appease her.

In recent years this half-a-mile wide crater-within-a-crater has begun to see renewed activity. Vents of steam and sulfur have accelerated and explosions of ash and debris rocked the area in 2008. Perhaps Pele tires of offerings of fruit and flowers and would instead prefer a new iPod?

Once you're sufficiently impressed with Halema'uma'u, head back to the last junction and take a right turn onto the Byron Ledge Trail.

[JCT] Take a right towards Kilauea Iki

Back in the forest it's in some ways a relief to be back on a more conventional trail. Enjoy the color of the foliage here, before we head into another crater.

[JCT] Right turn into Kilauea Iki Crater

The final 2.4 mile stretch along the Kilauea Iki Trail takes us across more lava beds, initially rough in terrain but smoothing out over time.

This lava surface may not have seen much action recently, but the smell of sulfur tells a different story. Stick to the trail, complete the switchbacks to exit the crater and soon you'll be back at the trailhead again.
