9. Muliwai Trail
Backpacker Magazine named this trail “The Best in Hawaii.” You can explore this scenic, trail with little to no effort. There are many swimming pools, black sand beaches, and a few other surprises. Make sure you check when it would be best to travel, some months are unbearably hot and unless you are looking to sweat a gallon within minutes, you should visit on a cooler week. If you like visiting ruins, you can also find a few old ruins that are in pretty good shape for their age.
