Oahu

Oahu (Hawaiian: Oʻahu) is the most populous of the Hawaiian islands, the third largest in size (after the Big Island and Maui) and the cultural, financial, and top tourist destination of the Hawaiian islands. As the home of the city of Honolulu, the state capital, and as home to over 85% of the state's population, Oahu is appropriately nicknamed "The Gathering Place."

Oahu is truly at the heart of Hawaii. The city of Honolulu is busy, and its Waikiki district even more so. Oahu is home to the only real metropolitan area in all the Hawaiian Islands. For some, this has been both a blessing and a curse for the island.

On the plus side, visitors to Oahu and local residents share in all the amenities and conveniences that only a large city such as Honolulu can provide—days spent dashing about, bustling nightlife, great restaurants, exciting cultural events and establishments, good public transportation, and a variety of shopping and lodging options. Combine this with the city and island's extensive beaches, parks, mountains, recreational areas, and quaint towns and this makes one enjoyable metropolitan area. On the minus side, Honolulu is a big city and has all the big city problems that come along with it, such as traffic, high cost of living, and some crime.

Honolulu may not embody the vision that some visitors have of Hawaii after looking at so many postcards: serenity and relaxation. True, one can relax on Oahu just by going to the right destinations on the island, you just need to know where to look. A calming oasis can be found as there are many resorts located outside of Waikiki that offer less crowded surroundings. Natural beauty can be found in the two mountain ranges, the Koolau and Waianae ranges. Some great hikes are just a short drive into the mountains from Waikiki. Secluded white sand beaches, funky beach towns, pounding winter surf on the North Shore. All of which can be found in other parts of Oahu.

So enjoy Honolulu and all it has to offer. But if you don't see the North Shore during the wintertime when monstrous waves pound the shore (think of the opening scene of the 1970s show Hawaii Five-O), then you have really missed something. Brave and experienced surfers attack these waves! If you don't take a drive through miles of pineapple fields, and if you don't take time to visit some of the white sand beaches, mountain trails, and scenery outside of Waikiki, then you really haven't seen all Oahu has to offer.

Two mountain ranges make up the island of Oahu. The Koolau Range (Hawaiian: Koʻolau) runs along the east side of the island and forms the backdrop for Honolulu; the Waianae Range (Hawaiian: Waiʻanae) runs parallel to the Koolau Range along the west side.

The majority of visitors to Oahu stay in Honolulu and its Waikiki district. The rest of the island is less visibly touched by tourism, with only a few B&Bs among the houses and natural sites on the Windward Coast and the North Shore.

Besides Honolulu, a city large enough to be a region of Oahu, there are a number of towns of note on the island:

• Kailua - The largest town on the Windward Coast, with secluded beaches and lush scenery.
• Kahuku - A small town on the North Shore.
• Kapolei - A relatively new town on the Leeward Coast that's a focus of suburban expansion, with few tourist attractions but a developing resort area.
• Nanakuli - A small town on the Leeward Coast.
• Waianae - Another small town on the Leeward Coast.
• Hale'iwa - A small and pleasant beach town that's the focal point of activity on the North Shore.
• Waipahu - A prominent bedroom community and former sugar plantation town in Central Oahu.
• Kaneohe- Known For its sheer natural beauty, you’ll be hard-pressed to find a more stunning Oahu neighborhood than Kaneohe, on the other side of the mountains from Waikiki. Kaneohe Bay has nearly 20 square miles of turquoise water.

• Waikiki. - The tourist center of the Hawaiian Islands, with its famous beach and block after block of highrise hotels sitting beneath the striking Diamond Head crater.
• Pearl Harbor in Western Honolulu is noted for the surprise attack of December 7, 1941 that launched the United States into World War II; today visitors will find a striking memorial atop one of the battleships sunk that day, and naval vessels open for tours.
• Hanauma Bay in Eastern Honolulu is arguably the best place for snorkeling in the islands, with a very accessible reef situated in the crater of a flooded volcano.

• Try windsurfing, surfing and body-boarding at Waikiki and (less crowded and more scenic) North Shore and Kailua Beach. - see Oahu Surf Conditions, Radar, and Forecasts.
• Enjoy horseback riding on the North Shore and Windward Koolau Range
• Explore hiking all over the island: in particular, Diamond Head State Park (excellent view of Honolulu and the surrounding area). Also visit Lanikai's Pillbox (leftover from World War II sitting above Lanikai). Gives spectacular view of Waimanalo, the Koolau Mountains, Kailua and the Mokulua Islands sitting in the distance. The Oahu Trailblazer adventure guide provides an overview of all the island's trails with maps, photos and hike descriptions. See Trailblazer Travel Books.
• Kayak on the Windward side to the Mokulua Islands which are a bird sanctuary and also offer encounters with turtles which have made a huge comeback in the Windward bay area. It is against state law to violate the sanctuary area. The beach on the islands is not part of the restricted zone, however.
• Circumnavigate the east half of the island: From Honolulu, take H1 east until it turns into Route 72. Follow Route 72 around the southeast corner of the island. Then go on Route 83, which goes along the east coast of the island around the northeast corner to the North Shore. Return to Honolulu along Route 99, Interstate H2, and Interstate H1. Unfortunately, it is not possible to circumnavigate the entire island because there is no road between the North Shore and the Leeward Coast around the northwest corner of the island.
• Driving tour around East-side of island gives spectacular views. Stop several times along the route to see blowhole, swim in secluded cove, hike up to the Lighthouse for amazing views or check out ancient Hawaiian drawings and Heiaus (Hawaiian temples).
• Drive up to the Round-Top Forest Reserve (excellent view of Honolulu and the surrounding area), or over the Pali Highway; be sure to visit the Pali Lookout.
• Viewing Marine Wildlife (the best 1/2 of Oahu is underwater!)- see Wild Side Specialty Tours to sail with whales, dive with dolphins, and snorkel coral reefs with turtles and tropical fish.
• If the hot weather is too much for you, go ice skating at the Ice Palace in Honolulu (see "Do" in the Honolulu article).

Although Oahu is generally not regarded as a premier dive destination, there are many reasons to consider diving here. The islands have fewer types of coral than any other part of the tropical Indo-Pacific, and reef health has been impacted by a variety of human forces, including population increases, shoreline development, land-based sources of pollution, increased sediments in the water, damage by tourists and divers, groundings, poor water quality from runoff and sewage treatment, and over-fishing. But Hawaii has a greater number of endemic tropical marine fishes than any other region except the Red Sea.

There are three MLCDs (Marine Life Conservation Districts) on Oahu - Hanauma Bay, Waikiki, and Pupukea. The MLCDs are designed to conserve and replenish marine resources. The taking of any type of living material (fishes, eggs, shells, corals, algae, etc.) and non-living habitat material (sand, rocks, coral skeletons, etc.) is generally restricted, if it is permitted at all.

Reef dive sites:

• Hanauma Bay - Water depths in the inner bay range to about 30 feet, and visibility is generally good. The outer bay is recommended only for experienced divers. Depths range up to about 70 feet, and there is a large finger coral reef on the left side.
• Pupukea - includes three dive sites on Oahu's north shore - Shark's Cove, Firehouse, and Three Tables - with depths ranging from 20-45 ft. Many ledges, arches, lava tubes and other features. From about May through October the water is generally calm, but surges are possible. During winter months current and wave conditions become extremely dangerous in all areas.
• Kahe Point Beach Park (also known as Electric Beach) An adjacent electric generating facility outflows clean warm water through two giant cooling pipes offshore. Easy beach entry when the surf is low, with depths ranging from 5-35'.
• Trench Dive - (also known as Haleiwa Ali'l Beach Park) Park your vehicle in Western parking Lot of the park. Entry is easy, walk to left side of Main building. Water depth is only 1-2 ft for about 100 m then starts to drop off. The wall starts at 10 ft and drops to about 90 ft. The trench was built to hide submarines. Southern wall is most dramatic.

Wreck dive sites:

• The Seaplane Wreck - a twin engine Beechcraft airplane off the west coast with a maximum depth of 100 ft (30 m). Sunk in 1986 as an artificial reef project.
• Corsair Airplane Wreck - a deep dive with a maximum depth of 107 F (32 m). A mostly-intact wreck submerged since 1945 when the pilot ditched it after engine problems during an exercise.
• Mahi Wreck - a former minesweeper/cable layer sunk off the west coast in 95 ft (29 m) of water, with the deck between 60-80 ft (18-24 m). Shortly after being sunk as an artificial reef project in 1982, Hurricane Iwa repositioned the ship 180 degrees.
• San Pedro Shipwreck - a former a Korean fishing boat resting in 85 feet of water with the main decks at 65 and 70 feet. Sunk in 1996 by Atlantis Submarines.
• Sea Tiger Shipwreck - Rests upright on a sandy bottom off the Waikiki coast at 130 ft (40 m), but dive depth is generally between 80-100 ft (24-30 m). Sunk on June 24, 1999 by now-defunct Voyager Submarines.
• YO-257 Shipwreck - Rests upright at 95 ft (28 m) off the Waikiki coast. Often in Rodale's Scuba Diving Magazine's top 5 of US best wrecks. Sunk in 1989 by Atlantis Submarines.

Some areas, including parts of Downtown/Chinatown, Pearl City, Waianae, Nanakuli, Waipahu, and Kalihi, are not very safe after dark. Officers from the Honolulu Police Department are extremely helpful to visitors and will steer you away from potential problems.

Some beaches are unsafe due to surf conditions or currents. Always check the Local Oahu Beach Conditions in advance to know the dangers. Check with the lifeguards and look for flags (Yellow=Caution; Red=Dangerous; Black=Extremely Dangerous). Underwater rocks and coral can be very shallow in some locations even with large waves, so know before you go. Some beaches (like Sandy's Beach) have very large very dangerous shorebreak at times. It is good to know general beach safety to understand the risks.

Take care when hiking on trails. Several trails are hazardous, especially after large amounts of rain, go with someone who is familiar with the area. It is very easy to get to dangerous locations that are not marked by signs or railing. When hiking near on rock shelves beside the ocean, dangerous areas are not blocked off. Understand the conditions of the oceans and take note how high up the water has splashed due to wave action. It is not uncommon to have areas that are safe and fun to explore until surf conditions change making them dangerous or deadly. If you fall into the water in high surf near rock walls, swim away from the rocks and shore, do not panic, call for help and swim parallel to the shore to location of little wave action or toward sandy areas.

Remember that as much as you need to keep yourself safe, you need to keep Hawai'i safe as well. Please practice the leave-no-trace principles to make sure everyone can enjoy the islands. It's not only illegal to do things like feed or hassle wildlife, take rocks, sand or plants, but it's also immoral and detrimental to the Hawaiian Islands. They are the most isolated land mass on the globe and have many species and landscapes that are struggling to survive under the pressures of tourism. Respect the 'aina the best you can. Do not cut trails, litter, or desecrate natural or man made sites.

To get to the other Hawaiian islands, fly Hawaiian Airlines or Mokulele Airlines from Honolulu International Airport. Mokulele also has flights from Kalaeloa Airport in West Oahu.
