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.

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).
