|This picture is not tilted. That's the upper slope of Mauna Loa|
Would you want to visit this barren blasted place? Perhaps. It depends on what you want to get out of a visit to the islands. If you are in stellar shape, the road's end is a trailhead for the shortest hiking access to the top of Mauna Loa nearly 3,000 feet higher (about 3.8 miles to the summit ridge and another 3 or so to the actual summit). It's a case of instant altitude sickness just waiting to happen. If you want to see one of the most unearthly places on Earth, it may be worth your time. If you haven't seen the important parts of Hawai'i Volcanoes National Park, then your precious time might be better spent on the south side of the gigantic mountain.
Speaking for myself, I was fascinated the whole way.
