Oahu is Hawaii's most visited island, but most visitors see only a fraction of it. This guide covers the full picture, from Waikiki to the North Shore and everything in between.
Waikiki is where most visitors begin, and it is easy to understand why. The mile-long beach is backed by a skyline of resort hotels with Diamond Head rising at its eastern end; one of the most recognizable backdrops in travel. The water is calm, protected by an offshore reef, and warm enough for comfortable swimming year-round. Surf lessons and outrigger canoe rides launch from the beach daily, and the sunset from the sand, with Diamond Head silhouetted against the sky, is genuinely spectacular. The strip of hotels, restaurants, and shops along Kalakaua Avenue can feel overwhelming, but the beach itself remains one of the great urban beaches in the world. Pearl Harbor is the most historically significant site in Hawaii and one of the most visited memorials in the United States. The USS Arizona Memorial, built over the sunken battleship where 1,177 sailors and Marines remain entombed, requires advance reservations; walk-up tickets are rarely available and the site fills months ahead during peak season. The broader Pearl Harbor Historic Sites complex includes the USS Missouri battleship, where Japan's surrender was signed in 1945, and the Pacific Aviation Museum, which houses an extraordinary collection of World War II aircraft. Allow a full day and book tickets as early as possible. The Diamond Head crater hike is the most popular trail on Oahu, a 1.6-mile round trip that climbs through the interior of an extinct volcanic crater to a 360-degree panoramic view of Waikiki, the coastline, and the Ko'olau Mountains. The trail is well-maintained but steep in sections, with a series of tunnels and staircases near the summit that were built during World War II as part of the crater's military fortifications. Start before 8 a.m. to beat the heat and the crowds; the parking lot fills quickly and advance reservations are required through the Hawaii State Parks system. The North Shore is the antidote to Waikiki; a 7-mile stretch of coastline between Haleiwa town and Sunset Beach that is the spiritual home of big-wave surfing. From October through February, the surf at Sunset Beach, the Banzai Pipeline, and Waimea Bay reaches 20–30 feet and draws the world's best surfers for a series of prestigious competitions. In summer, the same beaches are calm and swimmable. Haleiwa town is the most authentic non-resort community on Oahu, with independent restaurants, surf shops, and the famous shrimp trucks parked along Kamehameha Highway. The drive up from Honolulu takes about an hour and is worth every minute. Kailua and the windward coast represent Oahu at its most beautiful. Lanikai Beach, a short walk from Kailua Beach Park, is consistently ranked among the most beautiful beaches in the world, powdery white sand, turquoise water, and the twin Mokulua Islands sitting just offshore. Kailua Beach Park is excellent for kayaking and windsurfing, with consistent trade winds and a calm, reef-protected bay. The town of Kailua has the best independent restaurant and coffee scene outside of Honolulu proper. The kayak trip to the Mokulua Islands takes about 30 minutes each way and is one of the best half-day activities on the island. Honolulu's Chinatown is the most interesting neighborhood on the island for food and culture; a compact grid of streets lined with art galleries, Vietnamese restaurants, ramen shops, and produce markets. The Saturday KCC Farmers Market at Kapiolani Community College is the best farmers market in Hawaii, with local produce, prepared food, and coffee from farms across the islands. The neighborhood is walkable and best explored on foot; the contrast with the resort corridor of Waikiki, just two miles away, is striking. Getting around Oahu requires some planning. A rental car is essential for anything beyond Waikiki; the bus system (TheBus) is comprehensive and cheap but slow, and rideshare works well for nights out when parking is a challenge. The H-1 freeway connecting Honolulu to the rest of the island is one of the most congested roads in the United States during rush hour; plan drives outside of 7–9 a.m. and 4–6 p.m. The drive around the entire island (the circle island tour) takes about three hours without stops and is one of the best ways to understand Oahu's geography. The best time to visit Oahu is April through May or September through October, when the weather is excellent, the crowds are smaller than peak season, and hotel rates drop significantly. Whale watching season runs December through April, when humpback whales migrate to Hawaiian waters and are frequently visible from shore and on boat tours. The North Shore surf season runs October through February. Summer (June through August) is the busiest and most expensive period, with school holidays driving demand. Oahu's neighborhoods each offer a different experience. Waikiki is the resort corridor, convenient, expensive, and always busy. Ala Moana, just west of Waikiki, has the largest open-air shopping center in the world and a beautiful beach park that is the preferred beach of Honolulu residents. Kaimuki, a residential neighborhood in the hills above Waikiki, has the best concentration of local restaurants on the island. Manoa Valley, behind the University of Hawaii, is lush and green, home to the Manoa Falls trail and the Lyon Arboretum. Practical matters: Hawaii state law requires reef-safe sunscreen; products containing oxybenzone and octinoxate are banned to protect coral reefs. Water safety is serious; beaches without lifeguards can have dangerous currents and shore break, and the ocean conditions change quickly. Hanauma Bay, the most popular snorkeling site on the island, requires advance reservations through the city's online system and an educational video before entering the water. Diamond Head State Monument also requires advance reservations. Book both as early as possible, they sell out weeks ahead during peak season.
