From gorgeous beaches to cascading waterfalls in deeply etched valleys, the Garden Isle defines adventure, romance and blissful relaxation. Spot a humuhumunukunukuapua'a while snorkeling off Poipu Beach. Zipline above a rainforest canopy in Princeville Resort, or kayak past ancient heiau (temples) along Hawaii’s longest navigable river near Kapaa and Lihue.

Each of these coastal areas is home to Castle vacation suites that are gateways to vast island recreation. From hiking through Waimea Valley to sailing through Napali Coast sea caves or soaring above that dramatic landscape on a helicopter flight, Kauai wows with natural wonders.
