Oahu Travel Guide
Best Things to Do in Oahu
From snorkeling a volcanic crater to watching 30-foot waves on the North Shore, Oahu packs more variety into one island than almost anywhere on earth. Here are the 26 best experiences, ranked.
Snorkel Hanauma Bay
WaterA protected volcanic crater turned marine sanctuary with over 400 species of tropical fish. Look for yellow tang, humuhumunukunukuapua'a (Hawaii's state fish), parrotfish, moorish idols, convict tang, butterflyfish, and Hawaiian green sea turtles gliding through the coral. One of the best snorkeling spots in the Pacific: warm, calm, and stunningly clear. Reservations required ($25 entry); book online as spots sell out 2–3 days ahead.
Tip: Go first thing in the morning for the calmest water and most fish activity.
Hike Diamond Head
HikingA 1.6-mile round-trip trail to the rim of an extinct volcanic crater with sweeping 360° views of Waikiki and the Pacific Ocean. Manageable for most fitness levels with proper footwear. One of the most iconic hikes in Hawaii.
Tip: Go at sunrise to beat the heat and the crowds. Book your entrance ticket online. Walk-in spots are limited.
Visit Pearl Harbor & the USS Arizona Memorial
HistoryOne of the most visited historic sites in the United States. The USS Arizona Memorial floats directly above the sunken battleship where 1,177 sailors remain entombed. Deeply moving, educational, and essential for any first-time visitor.
Tip: The USS Arizona Memorial audio tour is free but sells out weeks ahead. Reserve online immediately.
Watch the North Shore Big Waves
SpectacleNovember through February, 20–30 foot waves roll into Pipeline, Sunset Beach, and Waimea Bay, drawing the world's best surfers and tens of thousands of spectators. One of the most spectacular natural spectacles on earth, and it costs nothing.
Tip: December hosts the Vans Triple Crown of Surfing at Pipeline. Check the contest schedule and go on a competition day.
Attend a Traditional Hawaiian Luau
CultureA genuine Hawaiian cultural evening featuring fire knife dancing, traditional hula, an imu ceremony (underground oven), kalua pig, poi, haupia, and open bar. Paradise Cove on the west coast and the Royal Hawaiian Luau in Waikiki are the most popular.
Tip: Book at least 2 weeks out, especially in summer. Arrive early for the best seats and the imu ceremony.
Learn to Surf in Waikiki
WaterWaikiki is the birthplace of modern surfing, with gentle, consistent waves ideal for beginners. Surf lessons are widely available on the beach, typically 90 minutes with a certified instructor. Most people stand up on their first lesson.
Tip: Book a lesson rather than renting a board solo. Instructors make the experience significantly more fun and safer.
Spend a Day at Kailua Beach
BeachConsistently ranked one of the best beaches in the United States, with powder-soft white sand, crystal-clear turquoise water, and far fewer crowds than Waikiki. The charming town of Kailua has excellent cafes, boutiques, and restaurants.
Tip: Arrive before 9 AM on weekends; parking fills up fast. Kayak to the Mokulua Islands offshore for an unforgettable morning.
Explore the Polynesian Cultural Center
CultureA living museum featuring six authentic Pacific Island villages: Hawaii, Samoa, Fiji, Tahiti, Tonga, and Aotearoa. Hands-on demonstrations, canoe rides, traditional crafts, and an outstanding evening show. One of the top paid attractions in Hawaii.
Tip: Buy the combo package that includes the evening show and luau. Dedicate a full day, at least 5–6 hours.
Swim with Sea Turtles
WaterHawaiian green sea turtles (honu) are everywhere on Oahu: snorkeling at Hanauma Bay, kayaking near Kailua, or simply lounging on Laniakea Beach on the North Shore. Swimming near them (but not touching) is an unforgettable experience.
Tip: Laniakea Beach (Turtle Beach) on the North Shore is the most reliable spot to see turtles on land. Visit in the afternoon.
Cage-Free Shark Diving
AdventureNorth Shore shark dive operators take you miles offshore to swim cage-free with Galapagos sharks and sandbar sharks. One of the most thrilling adventures available anywhere in Hawaii. Suitable for confident swimmers; no dive certification needed.
Tip: Go on a calm morning for the best visibility. Most operators run trips out of Haleiwa Harbor.
Take a Helicopter Tour
AdventureSee Oahu from 1,500 feet: the Ko'olau Mountains, Diamond Head, Pearl Harbor, the Windward coast, and the North Shore all from above. Doors-off tours are particularly spectacular. One of the most unique ways to experience the island.
Tip: Book doors-off if you're not afraid of heights. The photography is incomparably better.
Drive the Windward Coast
ScenicThe Pali Highway cuts through the Ko'olau Mountains to reveal the stunning Windward coast, with lush valleys, turquoise bays, and towering cliffs. Stop at the Nu'uanu Pali Lookout for one of the most dramatic views on the island.
Tip: Combine with a morning at Kailua Beach and lunch at a local cafe for a perfect full-day excursion.
Hike Manoa Falls
HikingA 1.6-mile round-trip jungle hike through lush rainforest to a 150-foot waterfall. One of the most accessible waterfall hikes in Hawaii, with no technical skills required. The trail gets muddy; bring shoes you don't mind getting dirty.
Tip: Go on a weekday morning and bring mosquito repellent. The trail passes through a real rainforest.
Visit Kualoa Ranch
AdventureA 4,000-acre working ranch in a dramatic valley featured in Jurassic Park, Lost, and dozens of other films. ATV tours, zip lines, horseback riding, kayaking, and movie location tours. One of the most beautiful and diverse activity venues in Hawaii.
Tip: Book the combo experience that combines 2–3 activities. The valley ATV tour is the most popular.
Eat Your Way Through the North Shore
FoodThe famous garlic shrimp trucks near Haleiwa are legendary: Giovanni's, Romy's, and others lined up just off the highway. Add Matsumoto's shave ice, acai bowls at Shark's Cove Grill, and a stop in Haleiwa town for the full experience.
Tip: Giovanni's shrimp truck is the most famous but also the most crowded. Romy's is equally good with shorter lines.
Snorkel Shark's Cove
WaterA natural lava rock cove on the North Shore that creates a protected shallow swimming area teeming with tropical fish and sea turtles. Spot yellow tang, parrotfish, moorish idols, butterflyfish, convict tang, moray eels, and octopus hiding in the rocky crevices. Free to visit, less crowded than Hanauma Bay, and accessible only in summer when the North Shore surf is calm.
Tip: Only safe for swimming in summer (May–September). Avoid in winter; the surf can be dangerously powerful.
Tour Pearl Harbor: USS Missouri and Pacific Aviation Museum
HistoryBeyond the USS Arizona, Pearl Harbor hosts the Battleship Missouri (where WWII ended with Japan's formal surrender) and the world-class Pacific Aviation Museum inside an original WWII hangar. A full half-day of history.
Tip: The Missouri and Aviation Museum require separate tickets from the USS Arizona Memorial. Plan 4–5 hours total for all three.
Explore Honolulu's Chinatown
Food & CultureOne of the oldest Chinatowns in the US, packed with dim sum restaurants, noodle shops, fresh fish markets, lei stands, and art galleries. Wander the alleys, stop at Maunakea Marketplace, and eat lunch at one of the family-run noodle shops.
Tip: Visit on a Saturday morning when the farmers market is running and the neighborhood is most alive.
Watch the Sunrise at Lanikai Pillbox
HikingA short but steep hike to two WWII-era concrete bunkers (pillboxes) on the ridge above Kailua with panoramic sunrise views over the Mokulua Islands and Kaneohe Bay. One of the most photographed views in Hawaii.
Tip: Start hiking 45 minutes before sunrise. Bring a headlamp and wear shoes with grip. The path is rocky.
Kayak to the Mokulua Islands
WaterTwo small islands just offshore from Kailua Beach, accessible only by kayak or paddle board. Crystal-clear water, nesting seabirds, and a pristine white sand beach on the larger island make this one of the best half-day adventures on Oahu.
Tip: Rent from one of the Kailua Beach kayak outfitters. The paddle takes 20–25 minutes each way in calm conditions.
Deep-Sea Fishing
AdventureOahu's offshore waters are world-class fishing grounds for mahi-mahi, ahi tuna, marlin, and wahoo. Half-day and full-day shared charters depart from Kewalo Basin near Waikiki daily. No experience needed.
Tip: Go on a shared charter for the most social and affordable experience. Full-day trips have better odds for larger fish.
Try Leonard's Malasadas
FoodLeonard's Bakery has been making Portuguese malasadas (fried dough rolled in sugar, filled with cream or custard) since 1952. A genuine Honolulu institution. The line is long but moves fast, and the malasadas are worth every minute.
Tip: Get there early on weekends or expect a wait. Order the original glazed and one filled. The lilikoi cream is exceptional.
Visit the Bishop Museum
CultureThe world's preeminent Polynesian natural history and cultural museum, with an extraordinary collection of Hawaiian artifacts, royal regalia, and Pacific Islander history. Often overlooked by tourists. It's one of the best museums in Hawaii.
Tip: Budget 2–3 hours. The Hawaiian Hall is the centerpiece, but the Science Adventure Center is excellent if you have kids.
Sail at Sunset
WaterCatamaran sunset cruises depart from Waikiki Beach nightly, offering 2-hour sails along the Honolulu coastline with open bars, snacks, and panoramic views of Diamond Head at sunset. One of the most romantic experiences on the island.
Tip: Book the cocktail cruise rather than the dinner cruise for a better value. Prices are lower Sunday–Thursday.
Hike Koko Head Crater
Hiking1,048 steps straight up an old military railway track to the rim of Koko Head Crater. One of the most challenging stair climbs in Hawaii. The views from the top over Hanauma Bay, Maunalua Bay, and the Ko'olau Mountains are extraordinary.
Tip: Go early morning. It gets brutally hot by mid-morning. Bring water and wear proper shoes.
Play Golf on Oahu
AdventureOahu has world-class golf courses across every region of the island. Turtle Bay Resort on the North Shore features the Palmer Course and Fazio Course, both with ocean views and coastal holes. Ko Olina Golf Club on the west side is a resort course set among lagoons with consistent trade winds. Hawaii Prince Golf Club in Ewa Beach offers 27 holes of championship play. Royal Kunia Country Club and Olomana Golf Links on the Windward side are beautiful alternatives with views of the Ko'olau Mountains.
Tip: Book tee times at Turtle Bay well in advance, especially in summer. Ko Olina is most accessible from Waikiki without a long drive.
What to Pack for Oahu
The essentials that make a big difference on an Oahu trip.
Reef-safe sunscreen
Required by Hawaii law at Hanauma Bay and recommended everywhere. Look for mineral-based (zinc oxide/titanium dioxide) formulas.
Rash guard or UPF shirt
The Hawaiian sun is intense. A rash guard provides all-day sun protection in and out of the water without reapplying sunscreen.
Snorkel gear
Bring your own if possible (mask, fins, snorkel) for a better fit. Rental gear is available at Hanauma Bay and many dive shops.
Water shoes
Essential for Shark's Cove, tide pool exploration, and lava rock entry points. Reef-safe rubber soles protect both you and the reef.
Light rain jacket
The windward side (Kailua, North Shore) gets occasional afternoon showers. A packable jacket fits in any daypack.
Dry bag or waterproof phone case
Protects gear on kayak trips, boat tours, and beach days. The Mokulua Islands kayak paddle gets splashy.
Reusable water bottle
Oahu's heat and humidity will dehydrate you faster than you expect, especially on hikes like Diamond Head and Koko Head.
Comfortable hiking shoes
Diamond Head, Manoa Falls, and Koko Head all require closed-toe shoes with grip. Flip-flops are not suitable.
Cash
The garlic shrimp trucks on the North Shore, farmers markets, and shave ice stands are often cash-only or prefer it.
Bug repellent
Manoa Falls trail has significant mosquito activity. DEET-free options work well. Apply before entering any jungle trail.
