Kauai is the oldest of the main Hawaiian Islands, known also as the "Garden Isle", because it is covered in lush tropical plants. Home to more sandy beaches than any island in the Hawaiian chain, a Kauai Island rent a car is the best way to get around and the only way to get to some of the most remote (and scenic) sites. Look for great deals on Kauai Island car rentals and save time and money to visit popular attractions like Kilauea Point Lighthouse, Waimae Canyon, and the Na Pali Coast.
Kauai is served by Lihue Airport (LIH), which is the main airport for visitors and commercial aviation. If you fly in here, Kauai Island car rentals are provided via complementary shuttle by Thrifty, Dollar, Alamo, Budget, National, Avis, and Hertz. Try Thrifty for the lowest rates, followed by Dollar and Alamo. Many companies offer additional locations throughout the island, including downtown Lihue, Hanalei, and Princeville, usually for lower rates than those at the airport.
You must present a valid driver's license and credit card issued in your name at most Kauai Island rent a car agencies (although some will take a cash deposit depending on a credit check), along with proof of insurance if you decline the vendor's coverage options. The minimum age to drive in Hawaii is 15 years, but most car rental agencies require drivers to be at least 25. Expect to pay about 25% more for gas than the average mainland US prices. Although most main highways are fairly easy to navigate and well maintained, many rental car companies have restricted areas, such as Polihale beach. Plan your route and check with the agency first, to keep from voiding insurance coverage if your rental car breaks down or gets stuck. All roads and street are well marked, and many feature red-capped warrior signs provided by the Hawaii Visitors Bureau that mark major visitor attractions and scenic spots. Always check the weather before driving long distances as sudden rainstorms can arise without warning. Follow Hawaii’s strict seatbelt laws and carry a cell-phone and emergency items with you in case of a breakdown or accident on a remote part of the island. Jaywalking is common on the island, so watch out for pedestrians, especially in congested areas.
