Yesterday, I posted about the first part of the Nāpau Trail in Hawaii Volcanoes National Park, which crosses extensive lava fields. Today’s post picks up from there, on the rim of Makaopuhi Crater, where the trail slips into dense forest on its way to the Nāpau Crater overlook.

It’s a remarkable contrast between the stark lava and thriving forest. Birdsong is continuous. Ferns of every kind grow in abundance. Bamboo orchids pop out here and there. And above it all, tall Ohia trees provide the backbone of the forest. This forested trail is clear, but somewhat overgrown. I was hiking in shorts and, at the end of the day, my legs were generously scratched.

Early on in this section, it’s possible to get views of Makaopuhi Crater. Also in this area is the junction with the Nāulu Trail, which starts out at the Kealakomo Overlook, farther down Chain of Craters Road.

The forested part of the trail is about 2.5 miles and towards the end of it is an old Pulu factory. The sign there reads: “Between 1851 and 1884 great quantities of pulu, the soft, reddish-brown fiber covering the coiled fronds of the tree fern (hāpuʻu), were harvested on Hawaii. Much of it was processed within these walls, later to be shipped from Keauhou Landing to foreign markets for use as stuffing in pillows and mattresses.” Unfortunately, in drier climates, pulu quickly breaks down so the industry collapsed.

A little farther along is another junction. To the left is the very basic Nāpau campsite, a few open flat areas and an outhouse. To the right, the trail continues to the overlook, where I was lucky enough to have a wonderful, clear view of Puʻu ʻŌʻō, busily pumping out sulphur dioxide and other gases, and of course, million upon millions of gallons of lava, currently entering the ocean on the southeast coast.

Picking the right day for the hike is not always obvious and weather changes quickly around here. At the visitor center, on the way in, it was completely overcast and drizzling, but by the time I got to the trailhead the sun was out and a nice breeze blew. The wind direction is also important. On this day, the northeast trades were blowing and the vog trailed away to the southwest, which is fine for this hike. But if the wind blows more easterly or south of east, then this trail would be downwind of emissions from the volcano, which could potentially be a dangerous situation.

The Nāpau Trail – Over the lava

In a couple of places the trail goes through sunken areas that channeled the lava.

The Nāpau Trail in Hawaii Volcanoes National Park, is a 13-mile round trip. It passes over extensive lava fields, plunges into dense forest, and ends at the Nāpau Crater overlook. The overlook offers a terrific view (weather permitting) of Puʻu ʻŌʻō, one of two active vents on Kilauea Volcano. In today’s post I’m going to cover the lava fields portion of the hike with the second part coming tomorrow.

From the Mauna Ulu parking area, the first mile or so is a well-trodden trail to Pu’u Huluhulu (hairy hill) cinder cone. The foot of Pu’u Huluhulu is where the Nāpau Trail branches off across the lava. It’s a stark landscape, but with lots of interest. The trail passes over surface flows and through channels where lava rivers ran.

The Park’s website notes that the Nāpau Trail “follows the path that magma takes as it makes its way underground from its source at the summit to the point where it comes to the surface near Puʻu ʻŌʻō.” The many steam vents around Mauna Ulu are testament to this.

And in this hostile landscape, nature is at work. The lava fields are dotted with tenacious plants establishing a toehold.  Ohia trees and ferns are most frequently seen, but grasses and other plants lend color to this sea of gray and black.

It’s 2.2 miles of unbroken lava from the Pu’u Huluhulu junction to the rim of Makaopuhi Crater, but at that point the trail changes in an almost surreal way. I’ll post that section tomorrow.

Signs: Kiholo campsite

One of the ocean-side campsites at Kiholo Bay on the Big Island of Hawaii
The campground at Kiholo is located at the end of a gravel road and is only open Friday through Sunday nights. It has eight sites that must be reserved in advance. There are portable toilets, but no other facilities, and no water. So what’s the attraction? Well, let’s see if the photo offers any clues. (Sorry, but the yacht doesn’t come with the reservation.)

Abstracts: A softer, gentler firehose of lava

One last photo from my trip to see the firehose of lava from Kilauea Volcano gushing into the sea. I tried a few longer exposures and I particularly like the effect of this one. More lava photos here.

Brant geese are rare visitors to Hawaii so it was nice to see this one puttering in the shallows at Kaloko-Honokohau National Historical Park, north of Kona. The rock it’s about to bump into is a Hawaiian green sea turtle. There were probably about a dozen of them there, either resting on the sand or bumping along the reef close to shore.

Going to the flow

Cyclists head to the Kilauea lava flow where it enters the sea.
I posted here about the current flow from Kilauea Volcano entering the sea, in a dramatic, firehose-like outpouring. In that post, I mentioned that the day after my visit, a cliff collapse caused the firehose to disappear from view. Things have settled down again and the firehose is once more visible, though another large crack not far back from the cliff is expected to cause another collapse soon.

From the Kalapana side, it’s about four miles to the viewing area and a thriving trade in bike rentals has sprung up. When I was down that way last July there were a few bikes available for rent. Now there are maybe 200 or 300 available from a large number of vendors in the parking lot. At the viewing area, bikes were piled alongside the road, and locked in clumps.

I preferred to walk, seeing the towering column of smoke and steam getting gradually larger on the way out, and enjoying a star-studded night sky on my return.

Kilauea Volcano’s firehose of lava

Lava from Kilauea Volcano’s Pu’u O’o vent enters the ocean as if from a firehose.Lava from Kilauea Volcano’s Pu’u O’o vent enters the ocean as if from a firehose.
I’ve posted before (here, here, here and here) about trips I’ve made to see the current lava flow from Kilauea Volcano’s Pu’u O’o vent. Lava first reached the coast on July 26, 2016 and has been pouring into the ocean ever since. However, on New Year’s Eve, much of the newly formed delta collapsed into the ocean taking with it a chunk of the older cliff. As a result, the lava tube carrying the active flow was suddenly left exposed and lava gushed out into the ocean as if from a firehose.

I was aware this was going on, but hadn’t really appreciated what it meant until this past Wednesday. Then, I read a report about the phenomenon, saw some photos, and realized this was something I had to see. Since the weather was favorable and it was early enough, I set out the same day.

After a three-hour drive and brisk hike I got to the viewing area, from the Kalapana side, around 5 p.m. These photos are from that trip. The top photo shows the firehose, lava gushing into the ocean in a constant, unwavering stream. When it hit the water, it generated a series of explosive reactions. The second photo shows the Lava Ocean tour boat nudging in toward the action as one of these explosions occurred. Below is a closer look at the stream with chunks of hot lava being hurled out into the water.

I stuck around until it got dark and then headed home – another hour-long hike and long drive – but it was so worth the effort. This was emphasized when, the next day, another cliff collapse caused the firehose to disappear from view. It might return, since the whole area is unstable, but it might also be gone for good.

I guess timing really is everything and I feel very fortunate that I was able to experience this phenomenon before it was gone.
