Keawaiki is as isolated as Big Island beaches get, mainly because the quickest way here is via a 15 to 20 minute walk over an Ê»²¹Ê»²¹ lava trail that looks like it was plucked from Dante Alighieri's darkest dreams. Your reward for getting here: a rocky, black-sand beach overlooked by a lone palm tree, and the blue ocean – which can be quite rough, so be careful if you swim. The path begins at a parking pull-off near Mile 79.
