What to Do in Oahu in 3 Days: Quick Highlights for a Short Stay
If you’ve only got 72 hours on Oahu, don’t worry—you can still squeeze in the best of the island. This 3-day itinerary is built to balance must-see attractions with time to relax and soak in those Hawaiian vibes.
Day 1: Hit the Ground Running in Waikiki
Morning to Midday:
After checking into a hotel in Waikiki (you’ll find everything from budget-friendly spots to beachfront resorts), head straight to the sand. Waikiki Beach is great for swimming, gentle waves, and people-watching. If you’re up for it, sign up for a beginner surf lesson—Waikiki is one of the best places in the world to try surfing.
Afternoon:
Stroll along Kalakaua Avenue, the main strip, where you’ll find everything from high-end shops to street performers. Make your way to the Duke Kahanamoku Statue, which honors the legendary surfer and Olympic swimmer. If you want a snack, grab some garlic shrimp skewers or a fresh acai bowl from a nearby food truck.
Dinner:
Head to Marugame Udon, a no-frills Japanese noodle spot famous for its hand-pulled udon and long—but fast-moving—lines. It’s cheap, delicious, and filling.
Evening (Optional):
If you’re not too tired, walk toward Kuhio Beach Hula Mound, where free Hawaiian music and hula performances are offered several evenings a week. It’s a relaxing way to settle into the rhythm of the island.
Day 2: Explore Diamond Head and the Scenic East Coast
Morning:
Start early with a hike up Diamond Head Crater. The trail is short (about 1.6 miles round trip), but it’s a steady climb with switchbacks, tunnels, and stairs. The payoff? Sweeping views over Waikiki and the Pacific.
Midday:
Jump in your rental car and take a scenic drive along Kalanianaole Highway, stopping at some of Oahu’s most photogenic coastal viewpoints:
- Halona Blowhole Lookout – watch water shoot through lava tubes into the air.
- Eternity Beach – tucked below the lookout, this tiny cove was featured in old Hollywood films.
- Makapuʻu Point Lighthouse Trail – a paved trail with dramatic ocean views and possible whale sightings in winter.
Afternoon:
Cool off at Lanikai Beach, one of the island’s most beautiful spots with soft white sand and calm, clear water. Nearby Kailua Beach is also great if you prefer more facilities.
Grab lunch in Kailua Town—try Buzz’s Original Steakhouse for a sit-down option or Lanikai Juice for smoothies and fresh bowls. Don’t skip a local-style shave ice before heading back.
Return to Waikiki via the Pali Highway, stopping at the Nuʻuanu Pali Lookout for misty views over the island’s lush Windward side.
Day 3: Dive Into History and Local Culture
Morning:
Dedicate your morning to Pearl Harbor. Start with the USS Arizona Memorial, a sobering tribute to those lost in the 1941 attack. If you have time, also tour the Battleship Missouri, where WWII officially ended, and the Pacific Aviation Museum.
Lunch:
There are a few casual spots nearby, or head back toward town and try one of Honolulu’s food trucks like Rainbow Drive-In for a local-style plate lunch.
Afternoon:
Visit the ʻIolani Palace, the only royal palace on U.S. soil, where you can learn about the Hawaiian monarchy. If you’re more into museums, the Bishop Museum offers a deeper dive into native Hawaiian history and artifacts.
Evening:
Watch the sunset at Magic Island, a manmade peninsula by Ala Moana Beach Park that offers a calm lagoon for wading and a picture-perfect view of the sun dipping behind the Honolulu skyline.
3-Day Tips:
- Rent a car on Day 2 to explore beyond Honolulu.
- Book your Pearl Harbor tickets online in advance—they go quickly.
- Start early to beat the heat and crowds at major attractions.
