Hawaii Travel Guide
4:04 PM
Hawaii (pronounced ha-VAI-ee by locals) is the 50th state of the United States of America. Situated nearly at the center of the north Pacific Ocean, Hawaii marks the northeast corner of Polynesia. While it was once a major hub for the whaling, sugar and pineapple industries, it is now economically dependent on tourism and the U.S. military. The natural beauty of the islands continues to be one of Hawaii's greatest assets. Honolulu is the state's capital, largest city, and cultural hub. Islands
Hawai'i is an archipelago of over nineteen distinct volcanic islands located over a geological "hot spot" in the Central Pacific. The Pacific plate on which the islands ride moves to the northwest, so in general the islands are older and smaller (due to erosion) as you move from southeast to northwest. There are eight major islands, six of which are open to tourism.
The island of Hawaii, also known as "the Big Island" to avoid confusion with the state, is the largest island, and lends its name to the whole island chain. Larger than all the other islands combined and still expanding in land area thanks to the active volcanoes on its southeastern coast, it is home to the major resort area of Kona, two of the world's largest mountains, and the world's most active volcano.
Oahu, nicknamed "the Gathering Place," is the most populous and developed island. Its southern shore is home to the city of Honolulu; four out of every five Hawaii residents call it home. It is the governmental and commercial center of the state, and Waikiki Beach is arguably the best known tourist destination in Hawaii. Outside the city are pineapple fields, and the North Shore of Oahu, which is known each winter as the home of some of the largest waves in the world. The USS Arizona National Memorial at Pearl Harbor is also very popular visitor destination.
Maui is the second largest island in the chain and is home to 10,023 foot (3,055 m) tall volcanic mountain crater of Haleakala. It is nicknamed "the Valley Isle" for the narrow plain between Haleakala and the West Maui mountains. On the west side of the island are the resort areas of Lahaina, Kaanapali, Kihei, and Wailea. On the east side is the tiny village of Hana, reached by one of the most winding and beautiful roads in the world.
Kauai, the "Garden Isle," is home to several natural wonders, such as the Wailua River, Waimea Canyon, and the Na Pali Coast. Mount Waialeale is known as one of the rainiest spots in the world.
Molokai, the "Friendly Isle," is one of the least developed islands in the chain. It is home to Kalaupapa, the leper colony on Molokai's north shore that was the home of Father Damien.
Lanai was at one time completely owned by Dole Foods and was the largest pineapple plantation in the world; it is now home to several exclusive resorts.
Niihau is a privately owned island with an entirely Native Hawaiian population. Until very recently, the island was off limits to all but family members and invited guests of the owners. Tourism to the island is limited to Helicopter, ATV, and hunting excursions originating on Kauai.
Kahoolawe, which was once a former US Navy bombing range, remains uninhabited. Efforts are being made to rehabilitate the island, but cleanup efforts continue.

Understand
Where tourism is concerned, Hawaii has something for everyone. The island of Oahu, the most populous and home to the state capital and largest city of Honolulu, is great for people who wish to experience the islands and still keep the conveniences of a large city. Rainforests and hiking trails are located just minutes from Waikiki Beach, one of the world's best tourist destinations. In the winter, large waves on Oahu's north shore turn the normally sleepy area into the surfing capital of the world.
On the other hand, those who wish to experience Hawaii at a slower pace would do well to visit one of the Neighbor Islands (the other, less populated islands around Oahu). All the neighbor islands offer opportunities to relax and enjoy the sun and scenery. Many of the natural wonders of the Islands are located on the Neighbor Islands, from Waimea Canyon on Kauai, to Haleakala on Maui, to Hawaii Volcanoes National Park on the Big Island of Hawaii. Numerous waterfalls and rainforests evoke memories of what the islands might have looked like before major corporations set their sights on Hawaii.
History
Polynesians migrated to, and established communities on, the islands of Hawaii before the arrival of Captain James Cook in 1778, who is widely credited as the first European visitor to the islands. At that time, each island was a separate kingdom. With the support of western advisors and weapons, Kamehameha I of the island of Hawaii conquered all the islands except Kauai, which acquiesced to his rule in 1810.
After Kamehameha II abolished the kapu (taboo) system, American missionaries came to the islands to spread Christianity. Their children would later become successful businessmen in the Islands. Pineapple and sugar cane plantations were established, and workers from other countries were imported as contract laborers. Later, their descendants would also become established as successful professionals.
The Hawaiian monarchy was overthrown in 1893 by a group of American businessmen. While the U.S. administration at the time refused to annex the former sovereign nation, in 1898 the United States did annex the islands, which became a territory in 1900, and a state of the United States in 1959.
Over the years, many major retail chains have expanded their presence in Hawaii, making the Islands look more and more like the continental United States, often at the expense of local businesses. Nevertheless, Hawaii remains culturally vibrant. Its population, descended both from the original plantation workers and from more recent arrivals, and in which no one group has a majority, is often cited as an example of multiculturalism at its best. There is a strong commitment to perpetuating native Hawaiian cultural traditions, as well as the cultural heritage of Hawaii's many immigrant communities from the Pacific, Asia and Europe. And certainly the environment is conducive to longevity...Hawaii has the longest predicted life expectancies of any U.S. state.
Weather
Depending on where you're located in Hawaii hi, the weather can be very different over even short distances. On the same day, on Oahu you might find sun over the beaches in Waikiki and rain only a few miles away in Manoa Valley.
Although the islands receive abundant amounts of both sunshine and rain, rain is more likely on the north and east sides of the islands, which face the prevailing northeasterly tradewinds (the "windward" side of the island), as well as the mountain peaks and valleys. The moist tropical air carried by the tradewinds is forced upward by the mountains, resulting in clouds and rain. Rain is less likely on the coastal areas of the "leeward" sides (the south and west sides) of the islands.
Although there are no "seasons" in the islands in the same sense as the rest of the U.S., the climate does go through annual cycles based on rainfall. The "wet" season in Hawaii (cooler temperatures and more rainfall) runs roughly from October to March, and the "dry" season (warmer temperatures and less rainfall) from April to September. There is therefore a higher probability of rain if you visit during the peak of tourist season in late December or January.
Hurricane season in the islands runs from June to November. Although Hawaii's relative isolation means that it is affected only rarely by tropical cyclones, a destructive storm will occasionally hit the Islands, such as Hurricanes Iwa and Iniki hitting Kauai in 1982 and 1992.
Overall, Hawaii is warm and balmy - when you step out of the plane you'll immediately notice that the air is soft and humid - and during the summer months the tradewinds provide a pleasant breeze. Daytime temperatures generally range from the low-80s in "winter" to the low 90s in "summer". During this time the beaches are at their busiest. There is usually no more than a 20-degree Fahrenheit (12 degree Celsius) difference between daytime high and nighttime low temperatures.
Consequently, besides your driver's license, credit card, camera, binoculars, and other essentials, it's best to keep your clothes to a minimum... a jacket, sweater/shawl, one or two pair of washable slacks/shorts, walking shoes, sandals and swim gear. Sunscreen is also essential since Hawaii's close proximity to the Equator translates into very strong sun radiation. The suitcase space you save can be used to fill up on island purchases.
Get in
Entry requirements for Hawaii are the same as for the United States, see the Get in section of the United States article.
For United States citizens, as Hawaii is part of the United States, travel to Hawaii from the U.S. Mainland is not much different from traveling between any other states. It is not necessary to bring a passport (or any documentation of U.S. citizenship) when traveling to Hawaii from the U.S. Mainland. The only paperwork that you'll be asked to fill out is required by the U.S. and Hawaii State Departments of Agriculture to prevent harmful plant pests and diseases from coming into Hawaii. Any fresh fruits, vegetables, flowers, and the like need to be declared and inspected by Department of Agriculture personnel at your point of arrival; some items may be prohibited from entering Hawaii at all. Penalties for non-compliance are stiff. Avoid bringing such items with you if at all possible. It's not worth the hassle.
When leaving Hawaii for the U.S. Mainland, all baggage must be inspected by U.S. Department of Agriculture inspectors at the airport. Be advised that fresh fruits (with the exception of pineapples and treated papayas) are prohibited from leaving the islands to prevent the spread of fruit flies. Consult the U.S. Department of Agriculture for more details. Bags are inspected by X-ray, so depending on the airport you leave from and the airline, be prepared to submit to as many as three checkpoints on the way to your Mainland flight: having your checked bags X-rayed in the ticket lobby, the TSA security checkpoint, and perhaps a separate carry-on bag inspection on the way to your gate.
Hawaii does not observe Daylight Saving Time.
By plane
Most flights from the mainland US and almost all international flights land in Honolulu on the island of Oahu. Direct service from the mainland is also available to Kahului on Maui, Kona on the Big Island, and Lihue on Kauai as well.
Depending on the airline, nonstop flights to Honolulu leave from most major gateway airports on the West Coast (as well as some smaller ones), as well as many major airports in the Midwest and East Coast. The flight from Los Angeles or San Francisco takes about 5 hours, comparable to a flight between the West and East Coasts. Thus, a flight from New York can take about 10.5 hours.
Jetstar is a budget Australian airline that recently started connecting Honolulu to several cities in Australia at very reasonable prices.
By boat
While the days where everyone arrived in Hawaii by boat are long gone, there are limited numbers of trans-Pacific cruises to Hawaii that leave from ports on the West Coast. However, one fascinating way to experience Hawaii is by taking a cruise ship between the islands.
Get around
By plane
Four inter-island airlines, Hawaiian Airlines [3], Island Air [4], Pacific Wings, and go!(a subsidiary of Mesa Air) provide virtually all flights between the islands. Go! started service in June 2006, positioning itself as a discount carrier. Consequently, as of summer 2006, there is a fare war underway between the four carriers; round-trip fares can be as low as about US$60 roundtrip, about half of what the going fare was in 2005. Travelers can save money and time by planning "triangle routes" that arrive in Hawaii on one island and leave on another.
Flight times run anywhere from 20 to 45 minutes. Flights can usually be purchased a day or two before departure, although this may increase the cost of traveling.
By boat
Hawaii Superferry runs a ferry between Oahu and Maui daily. Scheduled journey time is three hours for both Oahu-Maui. Advance-purchase off-peak (weekday) fares start from $44 for passengers and $59 for a car, not including varying fuel surcharges (~30%). There was a Kauai-Oahu route, but it has been indefinitely suspended by Superferry, Inc. because of community concerns following legal challenges and pending the completion of a court-ordered environmental impact statement. A route from Oahu and the Island of Hawaii will begin in 2009.
Charter boats sail and motor between some islands, especially the Maui-Molokai-Lanai area. But, crossing the channels between islands can be extremely rough going, even for Superferry passengers. Because of this, a few charter companies specialize in having boats delivered inter island and can meet you at your destination.
Norwegian Cruise Lines operates both U.S.-flagged and foreign flagged cruise ships between the islands. By February 2007 Maui departures are being eliminated, leaving Honolulu Harbor as the sole originating port. The two boats are the Pride of Aloha and the Pride of Hawaii.
By bus
On Oahu there is an excellent public transportation system TheBus. You can buy a booklet called "TheBus" at local ABC Stores giving route information on how to get around the island. Route Schedules are also available on The Bus Website . Public transportation systems are less developed on the Neighbor Islands.
By car
If you want to take your car to Hawaii, it will either need to be amphibious or freighted by ship, making this infeasible unless you plan a long-term stay in Hawaii. However, Hawaii is the only state that honors all other US state vehicle licenses until they expire.
Car rentals should be booked as soon as possible as the price charged is based on a supply/demand basis. The exception is Waikiki where you will not need a car on a permanent basis so just rent a car the day before you want one. Collision insurance coverage is very expensive through car rental companies (it can easily double your daily rate or more). Consider using a credit card with collision coverage. All U.S.-issued consumer Visa credit (but not debit) cards, many MasterCard cards and some American Express cards include secondary collision coverage; some American Express, Visa business and Diners Club cards offer primary coverage. Alternatively or additionally, prior to your trip, verify that both collision and liability (also called third-party) coverage from your own auto insurance company extends to rental cars. Car rental rates for 5 or 6 day periods are often the same as 7 day rentals. Use a credit card that includes medical and trip cancellation insurance benefits; if you cannot, consider buying trip insurance from your flight travel agent. View more on Hawaii car rental insurance.
Gasoline, while nowhere near the prices charged in Europe, is significantly more expensive in Hawaii than on the U.S. Mainland. Expect to pay about 10% more than the prevailing rate on the Mainland for gasoline in Honolulu. Neighbor Island prices can be as much as 10-15% above that.
Scooters are also an excellent alternative to getting around the islands. Rental rates are fairly cheap (about $50/day). The scooters are also fun to ride and are cheap on gas!
