Here, above the seacliffs in North Kohala's Hawi, sustainability meets luxury without sacrificing comfort. Hawaii Island Retreat generates its own solar and wind-turbine power, harnesses its own water, and grows much of its own food. Beautiful floors are sustainably harvested woods, and rooms take advantage of natural light and ventilation to keep energy usage low. Surrounded by 51 acres, 20 of which are a dedicated conservation area, the retreat feels both luxurious and completely hidden from the world. Handsome rooms have high ceilings, elegant doors, crown molding, European-size king and queen beds, and private balconies. More affordable options are available at the retreat's Yurt Village, which includes access to the resort's saltwater infinity pool and fitness center. Breakfast is sourced from the resort's garden supply, augmented by island-fresh ingredients from local farms. Book a massage in one of two pavilions that overlook the ancient council stones of Hawaiian royalty.
