Frequently Asked Questions
Kauaʻi is known as the Garden Isle for its lush landscapes, dramatic sea cliffs, Waimea Canyon, waterfalls, and a quieter island pace.
Helicopter tours, Nā Pali Coast cruises, snorkeling in Poʻipū, kayaking, ziplines, waterfall hikes, and scenic drives through Waimea Canyon are among the island's top experiences.
Poʻipū suits sunny south-shore beaches and resort amenities. Kapaʻa and Līhuʻe offer east-side convenience. Castle Resorts & Hotels offers stays in Poʻipū, Līhuʻe, Kapaʻa, and across the island.
Kauaʻi is a year-round destination. Spring and fall often bring pleasant weather and lighter crowds, while winter can bring larger surf to north-facing shores.
A rental car is the most flexible way to explore Kauaʻi. There is no road around the entire island, so plan routes in advance for north-shore and west-side outings.
