Must-See Attractions
Diamond Head: Oahu’s landmark — a volcanic crater hiking trail, 40 minutes one way to the summit, with panoramic views over Waikiki’s coastline. Arrive before 6 a.m. to beat crowds and avoid the worst heat. Summit elevation 232 metres; the view is spectacularly open — Hawaii’s most iconic hiking destination.
Hanauma Bay: A protected marine sanctuary with crystal-clear water and dense fish populations — paradise for snorkellers. Entry $25/person (includes environmental fee), $3/vehicle parking. Arrive in the morning when fish are most active. Note: closed on Tuesdays.
Polynesian Cultural Centre: An immersive experience across 6 South Pacific island cultures — Hawaii, Samoa, Tonga, Fiji, and more. Enter at 4 p.m. for the afternoon cultural villages, with LUAU dinner and show in the evening. Buy a combo ticket that includes the LUAU for a more complete experience.
Self-Drive Island Loop Recommended Route
Departing from Waikiki, clockwise loop:
- Morning: Diamond Head hike (trailhead right behind Waikiki)
- Midday: North Shore Pipeline (world-famous surf break — winter waves can reach 6 metres)
- Afternoon: Sunset Beach — watch the sunset, one of the world’s most beautiful
- Evening: Return to Waikiki — International Market Place is recommended for dinner
Flights and Accommodation
Flights: Cheapest connections are via Los Angeles or San Francisco — one-way approximately $200–350. Direct flights from Shanghai to Honolulu (approximately 9 hours) exist but are more expensive. Book Hawaiian Airlines 2 months in advance for the best prices.
Accommodation: Hotels along Waikiki Beach range from $150 (budget) to $800 (luxury ocean view). Outrigger Reef and Hawaii Princess are recommended beachfront options — 2-minute walk to the beach.
Food Recommendations
- Duke’s Waikiki: Founded by legendary surfer Duke Kahanamoku — ocean-view seating, signature Hula Pie (macadamia ice cream pie)
- Rainbow Drive-In: Affordable local Hawaiian plate lunches — Combo Plate under $10
- Giovanni’s Shrimp Truck: North Shore’s must-eat garlic shrimp food truck — intensely flavourful
Practical Information
- Best season: April–October is dry season; November–March is rainier but fewer tourists
- Car hire: Self-driving is the most convenient on Oahu; daily hire approximately $40–80 (QEEQ for comparison)
- Sunscreen: SPF50+ is essential — Hawaii’s sun is extremely intense
