The Nāpau Trail – Through the woods

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.

Hapu‘u fern

Hapu‘u ferns are endemic to Hawaii and can grow to 25 feet high, depending on the type. I like how the fronds uncurl, gradually revealing more details. The golden brown hair is called pulu. I found these in Hawaii Volcanoes National Park, which is one of the places where the fern grows best.

Kahuku hike

Hiking in KahukuHiking in Kahuku
Kahuku is part of Hawaii Volcanoes National Park. Its 116,000 acres was added to the park in 2003, an estate purchase of former ranch land. This purchase almost doubled the size of the park.

Not far from the southern tip of the Big Island, the entrance to Kahuku is about an hour’s drive from the main park entrance, but the two areas are contiguous, joined at the summit of Mauna Loa.

These photos are from a guided hike in Kahuku that I did a while back. The hike went through fairly dense old growth Hawaiian forest that had been spared because it was in a steep gully and thus not suitable for clearing for pasture. There was no real trail.

Currently this part of the park is closed because trees with Rapid ‘Ōhi’a Death (ROD) have been found in the lower part of the park and the goal is to prevent it spreading to other areas.
