Maui, a hiker’s wonderland, offers amazing trails, from meditative coastal beach walks to heady treks high atop a volcano. Hidden in cloud forests, see tumbling waterfalls, bamboo groves, and rare tropical birds. On the coast, watch water spout through natural lava-rock blowholes, take a dip in ocean pools, and savor deserted beaches. Wander across lava flows, examine ancient Hawaiian petroglyphs, or follow the King’s Highway that royalty once trod.
