FAQs about flying to Kaua'i

Kaua'i climate

Kauai has a tropical climate, but there is great diversity on the island. The wettest place on earth is, officially, the Waialeale Crater in the centre of the island, but just a few kilometres away are dry, sunny areas. There are temperate foothills and high mountain rainforests too. Daytime temperatures, year-round, are in the mid-20s Celsius (80s Fahrenheit) and the trade winds help to keep things cool and balmy.

Getting around Kaua'i

After landing on cheap flights to Kauai, the best way to get around is by rental car. There are shuttles, tour buses, taxis and public transportation but for maximum independence, driving is best.

What is good to know if travelling to Kaua'i?

Get to Lawa’i Road, Po’ipu, in the south of the island to see Spouting Horn. A natural wonder, waves rushing under the lava shelf burst through a small hole on the surface, expelling water up to 15 metres high. Evening is the time to be there, that’s when the water takes on the colours of the sunset.
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. Polihale Beach is Kauai’s westernmost point and its longest beach with 27km of soft, white sands.
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).
