Hawaii has quite an outsize history, considering that this archipelago has less acreage than Maryland and is more than five hours by air from the nearest major landmass. Travelers more keen on history and culture than beaches and mai tais will find plenty of interest in the state. I suspect it will surprise many to learn that Hawaii is filled with ancient remains, including picturesque fishponds, lava-rock roads, temple platforms and petroglyphs. The most impressive and evocative complex of Hawaiian ruins I’ve seen was in Molokai’s Halawa Valley, which we explored a few years ago with a “cultural practitioner” as part of an UnCruise itinerary.
