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 especially. 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 Hawaiian residents themselves are not left out of 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 Oahu and all it has to offer. But if you don't see the North Shore during the wintertime when monsterous 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.

There is no need to use your bankcard or to have the pass mailed to you if you go to the Biki office to purchase the monthly pass.
New Rail Project
Oahu and the City and County of Honolulu are currently working on a new elevated rail project to transport people more effectively on the island. The project is officially called the Honolulu High-Capacity Transit Corridor and is expected to be completed in phases between 2018 and 2021 (although due to financial issues, the rail may take even longer to complete). Some locals believe that the new rail transit will be named TheRail, after the currently existing TheBus system. It is expected to connect the southern Leeward Coast (commonly known as the West Side, or West Oahu) with Ala Moana Shopping Center in downtown Honolulu, via Aloha Stadium, Pearl Harbor, and the Honolulu International Airport.
The following are some of the more important major highways on Oahu. Both the common name and the state route number are given here. With the exception of H-1, H-2, and H-3 locals refer to most state highways by name, rather than route number.
- H-1 known as the Queen Liliʻuokalani is an interstate freeway that runs through the entire south side of Oahu. The west end is route 93 in Kapolei and the eastern end is route 72 in Honolulu. This freeway goes through Waipahu, Pearl City, Halawa, Daniel K Inouye Airport, Downtown Honolulu and end at Kaimui. This freeway is the largest and the longest freeway on Oahu. The H-201 is an alternate route that lets you drive directly to Honolulu and is the shortest freeway on Oahu. This freeway lets you bypass the airport.
- H-2 is an interstate freeway that runs from the town of Waipahu through Mililani to the town of Wahiawa in Central Oahu.
- H-3 is an interstate freeway that runs from the suburb of Aiea, through the windward communities of Kaneohe and Kailua, to the gate of Marine Corps Base Hawaii.
- Moanalua Freeway/H-201 is an interstate freeway auxiliary route that serves as an alternative route for H-1. It runs from the Middle Street Merge (H-1, H-201) in the community of Kalihi in West Honolulu to the H-1, H-3, H-201 merge in Aiea. Some freeway signs may still label Moanalua Freeway as Route 78, even though Route 78 has since become H-201 in 2004.
- Nimitz Highway/Ala Moana Boulevard (state route 92) runs from Pearl Harbor to Waikiki; it is the main route from the airport to Waikiki.
- Pali Highway (state route 61) runs from downtown Honolulu to the Windward town of Kailua.
- Likelike Highway (state route 63) runs from the Kalihi district of Honolulu to the Windward town of Kaneohe.
- Kalanianaole Highway (state route 72) starts from the east end of H-1 and runs through the East Honolulu suburbs around Makapuu Point, and through the rural community of Waimanalo, ending in Kailua.
- Kamehameha Highway (state routes 99, 80, and 83) is the main highway on Oahu, starting from Pearl Harbor, going through the leeward communities of Aiea and Pearl City, then through Central Oahu, around the North Shore, and along the Windward coast ending at the town of Kaneohe.
- Farrington Highway (state route 93) is two separate roads: the south side starts where H-1 leaves off in Kapolei and leads to the Leeward coast communities of Nanakuli, Waianae, and Makaha, ending at the south end of Kaena Point State Park. The north side starts from Waialua on the North Shore through the community of Mokuleia to the north end of Kaena Point State Park(the road used to go around the point but the part that actually rounded the point has been closed and replaced with a nature preserve. A trail connects the two portions).
- Fort Weaver Road/Kunia Road (state routes 76, 750) goes from Schofield Barracks near Wahiawa south to Ewa Beach.

Oahu has 128 beaches. The following is just a selection of the beaches:
- Kailua Beach Park - Located just below the Kaneohe Bay and directly above Bellows air force station, this beach is famous for its excellent swimming and wind surfing. With nice fine sand - perfect for sunbathing and recreational activities, and a backdrop of tiny offshore islands, this makes for one of Oahu's most beautiful beaches. Recently, the beach has suffered from erosion, removing a significant amount of sand from the shoreline. As a result, the space available on the beach has been severely reduced.
- Kualoa Regional Park - Located along the Northeast side of the island, this beach is rarely crowded and has a great view of the offshore island, Chinamans hat, so called this due to its resemblance of the peasants chapeau worn by rural Chinese. With Kualoa mountains in the background you might feel you are in the movie Jurassic park, due to the fact that Kualoa range is where much of the footage took place. Also this area was considered sacred by ancient Hawaiians due to the whalebones that would wash on shore that would be used for valuable tools and jewelry.
- Kahana Bay Beach Park - Located along the windward side of the island, directly across Ahupua'a O Kahana state park, this is one of Oahu's best kept secrets. This beach cove is nestled at the very bottom of the Kualoa mountains and is often over looked by people traveling up the coast due to the outlining of pine trees along the beaches edges. With its seclusion, calm waters and plenty of shady spots for those not fond of the too much sun, you can obviously see why this is one of Oahu's best kept secrets.
- Lanikai Beach - This small stretch of thin beach is home to some of the most clear and blue water you will find surrounding Oahu, and with views of the two beautiful offshore islands, known as the Mokuluas, you truly feel engulfed in the tropical setting.
- Ala Moana Beach Park/Magic Island - Known as "The path to the sea", this beach park is famous for its recreational activities. Located just west of Waikikis beaches and directly across from tha Ala Moana mall, this area features a 76 acre park located along the shore, and is often home to many family gatherings and company outings.
- Sunset Beach - So called due to the beautiful sunsets that occur almost everyday on this spot, this white sand beach is one of the longest running beaches on Oahu, stretching 2 mi (3 km) in length and between 200-300 ft (61-91 m) in width at some spots. In the winter months, Sunset beach is home to one of the best surfing spots on the island and features several international surf competitions. In the summer months during the calmer seas this is a nice spot swimming and snorkeling. There is a bike path that runs from Sunset Beach to Waimea Bay that is a great way to spend the day exploring the hidden spots that you cannot see from the main road. Bike rentals can be found at Paradise Baby Co. there are adult bikes and kids. Spending the day on the North Shore is a great idea because there is so much to see.
- Ehukai Beach Park - Also known as "Reddish tinged water", this also home of the famous Bonzai Pipeline. In the winter months this beach features 30-40-ft (9-12 m) waves, when the swells are high, and frequented by many of the worlds best surfers. Part of the triple crown surf tournament, I would stay out of the water in the winter months unless you are familiar with the surf, due to the fierce breaking waves and strong undertow. However in the summer months the calm ocean makes a good spot for swimming and a good sandbar. Always check with a life guard at this beach before entering the water.
- Waikiki Beach - Meaning "sprouting water", this beach runs along Kalakaua Ave. and is home to many of the areas featured resorts. Often filled with tourists and guests of the hotels that line the beach, this area is where you can take some of the famous catamaran rides that are manned by the beach boys, not the band, but true beach boys. The calm surf and shallow waters makes a nice spot for wading in the waters, bodysurfing, and beginning surfers.
- Waimea Bay Beach - Located on the North Shore, in the winter months this is home to some of the largest and most dangerous ride-able surf in the world, with waves reaching 30 plus ft (9+ m), and with in-shore breaks often at 12 ft (4 m), experienced swimmers and surfers need only apply. However in the summer months the calm surf makes for nice swimming and with a nice size beach is great for sunbathing. If you are brave enough you can climb "da big rock", which is a popular free jump spot, and has platforms to jump off at 5 and 18 ft (1.5-5.5 m). Another beach that it is a good idea to check with a lifeguard.
- Sandy Beach Park - Located along the windward side of the island just past Halona Beach Cove, with calm surf, this is a superb spot for swimming and amateur bodysurfers. However most of the year there has somewhat rough surf and many of the best bodysurfers on the island call this beach home, because the waves here are rivaled by no where else on the island.
- Bellows Beach Park - Located right near Bellows air force station, this beautiful beach has shallow water and small consistent waves which makes for good swimming and beginning surfers.
- Hale'iwa Beach - Located in the Historical town of Hale'iwa this brown sanded beach is one of the few spots on the island where you can sit on the beach and watch the sun rise and set. With plenty of beach to lay out and being within walking distance of shops, eating, and sightseeing this is an attractive family spot.
- Halona Beach Cove - This beach is also nicknamed Eternity beach, receiving the name eternity because of the love scene that takes place on this beach from the movie "From here to Eternity". Most tourists usually go to this spot on the windward side of the Island just passed Hanauma Bay to view the Halona blowhole. The only way to get this beach though is to scale down the somewhat steep cliffs that protect this tiny but very scenic beach. Also beware of the sea turtles that frequent the spot, although they will not harm you, if you are caught touching them or trying to ride them, you will be fined.
- Barbers Point - Located on the ewa part of the island, this beach is frequented by many men and women in the armed forces due to the base that is just down the road. Also due to its small surf and scarce crowds it is not a bad beach for the beginning surfer. With a bar located right on the beach, open on weekends, and nice views of Honolulu, this beach is a nice spot to get away from your more touristy spots.
- Ko'Olina - The resort famous for housing many of the pro bowlers that visit every year in February, also features some of the most beautiful man-made beaches on the island. The 4 lagoons, named Kolola(whale), Hanu(turtle), Naia(dolphin), and Ulua(fish), feature some of the most beautiful sunsets that you will not find anywhere else on the island. With literally no surf the lagoons are often nice to just float around in. Given that the lagoons are about 30+ minutes (rush hour makes it over an hour) from Waikiki these lagoons are generally not crowded and only frequented by locals and guests of the resort.
- Three Tables - This beach located off the Kamehameha Highway, North Shore, and is sandwiched between Sharks cove and Waimea Bay, it features some very nice snorkeling. Beware of the surf in the winter months though. The waves can sometimes reach 30-40 ft (9-12 m) in these areas depending on the swells. Therefore most of the snorkeling and the wading the many tide pools along this beach is done between April and October.
- Pokai Bay Beach Park - Hawaiian for "Night of the Supreme one", this beach is named after the Hawaiian chef Pokai who according to legend brought and planted the first coconut palm tree on the island. This west shore beach is one of the most protected beaches on the island even during the months of rough surf, which makes for nice swimming conditions.
- Makapu'u Beach Park - Hawaiian for "Bulging Eyes", this beach is located just below Makapuu Point, which is Oahu's eastern most point. Popular for its bodysurfing and picturesque views of Rabbit Island, this beach is a very appealing yet relaxing spot, although beware of the rough surf, strong shore break and undertow, that can arise through-out the winter months.
- Mokule'ia Beach Park - Located on the northwestern tip of the island, this long white sandy beach is frequented by many of the local Hawaiians for its enticing windsurfing conditions and nice fishing spots.

Waikiki offers numerous bars, and Kuhio Avenue in Honolulu is home to most of that city's bars and nightclubs.
Within Honolulu, and particularly in Waikiki there are a vast number of lodging options. Outside of these areas there are very few hotels on the island, but there are vacation rentals. Due to zoning regulations some vacation rentals only accept stays of 1 month or longer.
Oahu is generally safe however as in any city crime and thefts are common. Honolulu and the Oahu have fewer crime incidents than the mainland but tourist should still be aware that pickpockets and be aware of surroundings.
Honolulu Police Department serves the entire island of Oahu.
The Honolulu Police Department have a mixed fleet of marked vehicles and an subsidized vehicle program in use. Marked cars are white with blue stripes and white lettering between the blue stripes HONOLULU POLICE.They also have unmarked cars for detectives and officers of a certain rank can purchase a personal vehicle for private and police usage. The car model can be any make or model but it is required to meet department guidelines and regulations. Subsidized vehicles are unmarked cars however they can be easily identified with a blue light beacon on the roof of the vehicles. Any subsidized cars with their blue lights on their roof means the officer is on duty. The Honolulu police department along with other law enforcement agencies on the neighboring island have their blue cruise lights on while on patrol. Cruise lights will remain lit but not flashing. This is to promote an active police presence while also deterring crime. When they are flashing they are either responding to an emergency call, pulling you over, or stopped at a scene.
The island of Oahu along with the rest of the Hawaiian Islands are susceptible to natural disasters. While volcano are not currently active on Oahu other volcano on Maui and the Big Island may have a affect on all islands. The most common natural disaster threat to Hawaii is hurricanes, earthquakes and tsunamis.
