The minibus pulls away from Waikiki before sunrise, headlights cutting a bright ribbon along Kapiolani Boulevard. Through the window, Diamond Head’s ridgeline slides by — a rounded silhouette against a sky that is quickly turning the color of guava. The guide’s voice is casual but precise: today’s route stitches together volcanic ridges, pineapple fields and surf breaks, and promises a snorkel stop where the reef will dare you into its warmer, fish-lit shallows.

Byodo-In Temple charges a modest entry fee and local stands take cash for fruit and macadamias.
