Ka’u Desert Trail
This week’s Sunday Stills challenge theme is ‘I’d Rather Be…’ See more responses here.
It had been a while since I went hiking, for various reasons, and it’s something I was missing, something I’d rather be doing. So last week, I headed down to Hawaii Volcanoes National Park to try the Ka’u Desert Trail. This backcountry trail has been on my list for a long time, but I had never done it before. For one thing, it’s about as far from my house as one can get on the island. For another, it’s directly downwind from Kilauea Volcano, so when the volcano is active and the trade winds are blowing, gasses blow across the length of the trail.
The latest eruption of Kilauea is currently either paused or over, so gas emissions are much reduced, and last week, the trade winds had given way to winds from the southwest. So off I went.
The trailhead is several miles west of the main entrance to the park, with a strip of parking along the highway. The first mile of the hike is also known at the Footprints Trail. It’s a sort of paved path that threads through ohias to a small building that houses footprints left by early Hawaiians in volcanic mud and ash. Alas, I couldn’t identify any footprints in the display. Shortly after the footprints, the path breaks out of the vegetation into open lava fields. This isn’t a tropical Hawaii walk, this a bleak hellscape Hawaii walk. Or is it?
The trail ascends gently to the only junction for miles around, at Mauna Iki. To the left is a trail back towards the heart of the park. The Ka’u Desert Trail heads to the right and into backcountry wilderness. Mauna Iki was the site of an eruption in 1919 and the trail traverses the lava fields from this eruption.
Much of the trail is over pahoehoe lava, which is rounded and much easier to walk on than jagged a’a lava. The trail is marked by cairns and single rocks placed alongside it. It’s pretty easy to follow with just one or two parts where attention has to be paid to make sure one doesn’t stray.
It wasn’t far along this part of the trail that I first encountered blue lava. That’s right, blue lava. Who knew? But not just blue. There’s bronze, pink, red, orange, gold, and who knows what. I’ve seen colorful lava on the Puna Coast Trail, but this was more varied and quite wonderful. In places the trail crossed this colorful lava and I felt bad for walking on it, though as I hiked I could see many more patches of color out in the lava fields. It’s not wise to leave the trail since there are many lava tubes, some with very thin ceilings.
This is an out and back trail and I turned around once I reached the Kamakai’a Hills, after about 5 miles. It’s another 2 or 3 miles to the next junction where there is a small cabin.

Jeweled Anemone Crab
I spotted this Jeweled Anemone Crab scuttling over some very uneven rock and coral, but it was still able to move at a pretty good pace. The Jeweled Anemone Crab is a hermit crab, meaning it lives in a snail shell, either one it found unoccupied, or one from which is evicted the current tenant.
This one looks to have found a colorful shell, but looks are deceiving. The shell isn’t visible at all, because it’s covered by at least four large anemones! These are Calliactis polypus anemones. They give the crab some protection because, if disturbed, they shoot out stinging threads. In return, they get transportation and possibly scraps of food from the crab.
Siphonophore
I was snorkeling recently when I saw this strange tubular stringy thing. That’s not a scientific term. My first thought was that it was a Chained Salp, a tunicate that is a colony of individual Salps. But this one seemed a bit different. There was the main tube, but also thinner strings hanging off it.
I started taking photos, which was a bit of a trick in the lumpy swell. I wasn’t worried about getting too close since Chained Salps are harmless. I wasn’t worried until I got too close and realized I’d been stung on the hand by some those tendrils! That was enough for me and I headed to shore.
Back at the house, I couldn’t identify it in my book so I emailed a fellow snorkeler who is well-versed in these sort of things. She had encountered these before and identified it as a Siphonophore (Thanks, Wendy.). Like the Chained Salp, this is a colony of individuals, but unlike the harmless salps, siphonophores have stinging tentacles which they use to catch prey.
Possibly the best known Siphonophore is the Portugese Man-Of-War, one of which had stung a fellow snorkeler just a few days earlier. His wounds were very painful, but I got off easily, with just red welts and a mild burning sensation for a couple of hours.
Homeward bound
A paddleboarder heads back to the shore on a gray, but not too windy morning recently. That’s a slice of Maui in the background.
Cauliflower coral
A pair of Fourspot Butterflyfishes disturbed a pair of Arc-eye Hawkfishes perched in a head of Cauliflower Coral, as they often do. The coral head is doing OK, but areas of it have died off, probably during one of the coral bleaching events that have happened in the past few years, where the water gets too warm.
I can get chilly fairly easily when I go swimming, but for me, it’s more distressing when the water feels oddly warm because I know this is bad news for the corals.
A traditional sail
This little sailboat is a modern rendition of a traditional Hawaiian style. The two hulls are common in various forms in Polynesian culture and the sailing rig features a Hawaiian Peʻa sail, otherwise known as a Crab Claw sail. These sails used to made from the woven leaves of Hala trees.
On this boat, the sail is made from a modern material and it’s speedy progress through the water wasn’t down the the light breeze, but rather an outboard motor, which is also not traditional!
Signs: Heineken Sailboat
Back in the day, I used to make home brewed beer. I needed bottles to put the beer in and that required emptying bottles that formerly held beer. Heineken was one of the many brands that were pressed into service. But there was one problem. Those green bottles were made with thinner glass and had a tendency to blow up under the pressure of my home brew.
I kept my beer brewing bottles in my wardrobe and the Heineken bottles’ volatility meant that my clothes acquired a certain aroma. It’s probably why I wasn’t more successful in the job I had at that time!
None of this has anything to do with the sign of course, but any time I see the Heineken name I immediately associate it with those days.
