MORNING Touching down in Kona, you might think, Um, have we landed on the moon? Otherworldly black lava rock ripples across the sunny Kona-Kohala Coast, where you'll find all the top resorts. Pick up a rental car—driving through the lunar landscape is half the fun—and ride 15 minutes to the insanely luxurious 243-room Four Seasons Hualalai (left), where you may catch a glimpse of Cameron Diaz or Rachel Zoe. Think seven outrageous pools, an apothecary-style spa, and an open-air gym worth setting a wake-up call for. Rooms from $545; Four Seasons.
AFTERNOON Park it at the adults-only Palm Grove pool with a yuzu-margarita shave ice (like a snow cone—with booze).
EVENING Stay in for a seaside farm-to-table feast at Pahu'ia; 90 percent of what's in the kitchen (Hamakua mushrooms, grass-fed beef) is sourced from local farmers.
