The Chain of Craters Rd is an interesting road through lava beds to the Holei Sea Arch, where the lava beds end at the sea. It goes by several other sites, including craters and the Pu'u Loa Petroglyphs. It allows one to see some interesting sites and it's definitely worth a visit if it's open beucas ethrouhg most of the years since it was first built it has been wholly or partially closed due to new lava flows. When we went in 2016, it was closed. This year, 2023, it was open all the way to the Holei Sea Arch. Some of the sites to see are not necessarily that impressive on their own, but as a whole they are very interesting. The sea arch is small and one is not llowed to get very close to it, but it;s interesting to sea this area where the lava has flowed all the way to the sea. The petroglyphs are early Hawaiian carvings in the rock and are an interesting site, and the whole landscape is interesting. The road dead ends at the sea arch, with a car park and toilets. One must drive all the way back along it, so keep that in mind. read more
