Maui has a reputation for luxury. Still, a stay at Montage Kapalua Bay, perched on an ocean-facing cliff on the island’s northwestern shore, isn’t for the faint of heart—or light of wallet. The experience begins at the entrance, where tranquil koi ponds set the tone for an impressive array of pools and waterfalls at the center of the 24-acre property. The 56 palatial residence-style villas encourage hunkering down—each is equipped with a kitchen with marble countertops and wine refrigerators, deep soaking tubs and walk-in showers, and washers and dryers—but do venture out. The concierge can arrange for everything from fishing charters to zip lining. Prefer quieter pursuits? Opt for a restorative seaweed cocoon treatment performed in one of the spa’s outdoor pavilions.
