With fascinating history and some of the best hiking in the world, Hawaii is home to a variety of hiking trails that can also double as a history lesson, many of which lead you to places that have long been abandoned. While many of these hikes will lead you to ancient Hawaiian temples, others still will lead you to places with a little more recent history: military bunkers.

Nowhere will you find a higher concentration of abandoned pillboxes — or concrete dug-in guard posts — than on the island of Oahu. There are the Lanikai PIllboxes on the windward coast, Pu’u O Hulu Kai on the leeward coast, and Diamond Head State Monument on the southern shore. But perhaps the most underrated pillbox hike is Ehukai, a hidden gem found on the north shore above the Banzai Pipeline. Let’s start our adventure, shall we?
