As part of our visit to Hawai’i Volcanoes National Park on the Big Island we took a 1.4 mile round trip trail across a cooled lava flow. The trail was rugged and rocky but led us to the Pu’u Loa Petroglyphs. There are some 23,000 images and are said to be . . . “dated geologically between AD 1200-1450.” (NPS)
We drove our black Charger through a series of switchbacks and found the trailhead to the petroglyphs.
It was a great experience to hike over a lava field and search for cool looking petroglyphs (our favorite being the Honu!).
Very cool! On my recent road trip “out West,” we inadvertently came across a very similar lava field (it’s specifically compared with such flows in Hawaii.) I have a few photos of it at the bottom of this post;
