Unless you’re on a fairly leisurely schedule, you’ll need a car or other motorized vehicle to see and do everything on Kauai, which has one major road—one lane in each direction in most places—that rings the island except along the Napali Coast. During rush hour, from about 6 to 9am and 3 to 6pm, the road between Lihue and Kapaa—the central business district—can turn into a giant parking lot, even with a third, “contra-flow” lane whose direction is determined by time of day. Bypass roads in Kipu (when heading north from Poipu) and Kapaa (when heading south) can alleviate some of the stress, but plan accordingly.
Note: The top speed is 50mph, with many slower sections in residen-tial and business areas. Addresses in this chapter will use Kaumualii Highway for Hwy. 50 and Kuhio Highway for Hwy. 56/560, following local convention. Some addresses use a single number before a dash, which simply indicates one of five island divisions. Since highway addresses can be hard to spot (if marked at all), directions may be given with mile marker numbers, cross streets, and/or the descriptors mauka (toward the mountains) and makai (toward the sea).
The official mailing address of sites in and around Poipu Beach is Koloa, which GPS devices may require. This chapter lists them as “Poipu” to distinguish them from Old Koloa Town and environs.
By Car—All of the major car-rental agencies are represented on Kauai. At the airport baggage claim, cross the street to catch one of the frequent shuttle vans to the rental lots. Avis (www.avis.com; 800/230-4898) also rents cars from the Grand Hyatt Kauai and Princeville Airport. Be sure to book early for peak periods. Discount Hawaii Car Rental (www.discounthawaiicarrental.com; 800/292-1939) may have cheaper options for last-minute bookings; it also offers free pickup for cruise passengers.
By Motorcycle, Moped, or Scooter—Riders 21 and older with a heavyweight motorcycle license can rent a “hog” from Kauai Harley-Davidson (www.kauaiharley.com; 888/690-6233 or 808/212-9469) outside Lihue. Rates for a Sportster start at $99 for 24 hours, with unlimited mileage; bigger rides start at $179. Kauai Mopeds (www.kauai-mopeds.com; 808/652-7407) in Lihue offers two-person scooters with similar age and license restrictions; daily rates start at $75 for models with a top speed of 52mph, and $110 for those reaching 75mph. For cruising back roads (directions provided), those 18 or older with a driver’s license can rent a single-person moped with a top speed of 30mph for $65 a day.
By Taxi, Rideshare or Shuttle—Set by the county, taxi meter rates start at $3, with an additional $3 per mile; from the airport, it’s about $65 to Poipu and $117 to Princeville, plus 40[ce] per item of luggage, and $4 per bulky item. You can also arrange private tours by taxi starting at $120 for 2 hours. Call Kauai Taxi Company (www.kauaitaxico.com; 808/246-9554) for taxi, limousine, or airport shuttle service. Ride-sharing app Uber came to Kauai in 2017; pricing varies by demand, but a typical rate from the airport to Poipu is $34 and to Princeville, $63.
Solo travelers who don’t use Uber will save money taking Speed-iShuttle (www.speedishuttle.com; 877/242-5777) from the airport ($42 to Poipu, $72 to Princeville), but be aware it may make multiple stops. Pono Express (http://ponoexpress.com; 800/258-6880) offers airport cab service ($50 to Poipu) and sightseeing tours in vans accommodating one to 14 passengers; rate is by vehicle or by hour. Once in Poipu, book a free ride on the Aloha Spirit Shuttle (www.poipu-shuttle.com; 808/651-9945); Doug Bean’s 12-person open-air tram—a former Disneyland people-mover built in 1965—shuttles locals and visitors around resorts and restaurants from 6 to 10pm Sunday–Thursday; tips are appreciated. A 45-minute sunset “cruise” on Bean’s newer 22-person trolley costs $25.
By Bus—Kauai Bus (www.kauai.gov/bus; 808/246-8110) has daily service between Kekaha and Hanalei, including stops near several Poipu and Lihue hotels, the central Kapaa hotel corridor, the Princeville Shopping Center, and Hanalei. Note: There’s also an airport stop, but suitcases, large backpacks, and surfboards are not allowed on the bus. The white-and-green buses, which have small bike racks in front, run more or less hourly from 5:30am to 10:30pm weekdays, and 6:30am to 6pm on weekends and holidays. The fare (exact change only) is $2 for adults and $1 for seniors, 60 and older, and children, 7 to 18.
By Bike—Due to narrow (or nonexistent) shoulders along much of the main highway, relying on bicycles for transportation is generally unsafe. For recreational routes, including the Ke Ala Hele Makalae coastal path on the East Side, see “Biking”.
