We thought that the Holei Sea Arch was the best part of the Chain of Craters Road. It is really quite a spectacular ending to this scenic road. There is a short walk of about 1000 feet from the parking area at the end of the road to the viewpoint. It's worth the walk. There are restrooms here; always good to know,

45 minute drive from visitor center with many sights along the way. Approximately 1/2 mile walk from parking to the arch view. Fun to see but to us not as interesting as the other park sites.

Nice parking area. Short walk to view the sea arch. Bathrooms on site. It was a nice place to stretch our legs after driving the Chain of Craters Road from Volcano before we turned around and went back up.

The Holei Sea Arch is at the end of the Chain of Craters Road. The drive ends at a parking area with toilets amongst the lava flows at the edge of the shore. There is a short walk to the area where you are allowed to walk out to a spot overlooking the shore, with the waves crashing against the lava-rock cliff. Along it is the Holei Sea Arch. It is fairly small and not easy to get a good picture of since the current viewing area is not that close to the arch itself. The Chain of Craters Road has, in the decades since built, been several times closed or partly closed due to lava flows, and the older viewing area remains can be seen on the walk, having been largely destroyed by lava.

It takes about 45 minutes to drive from the visitor center to the end of the Chain of Craters Road where the arch is. But more than likely, you are going to drive at least part of the road to get to the popular lava tubes so the extra time required to drive out and back isn't that bad. When you get to the end, you still have a 10 minute walk to get to the viewing platform. You aren't that close to the arch but I could use the zoom on my iPhone for some pretty decent pics.
