FAQs about flying to Kaua'i

Kaua'i climate

Kauai has 80km of sandy beaches, all of them free. Ke’e Beach is the most visited. The Kalalau Trail begins at the western end of the beach. Makua Beach, on the north shore, is known to surfers, snorkellers and divers as Tunnels. Salt Pond Beach Park is a great place to see Monk Seals.

Popular hiking trails include the Kukui Trail, a 8km hike that drops into Waimea Canyon (Hawaii’s Grand Canyon); the Kuilau Ridge Trail, a 6km round trip; and the Kalalau Trail, which offers stunning views of Na Pali Coast and Kee Beach (a great snorkelling spot).
