Destination guide

Honolulu: Waikiki, Pearl Harbor and the North Shore

Honolulu is the Hawaiian Islands' gateway and the only one with nonstops from most of the mainland. Waikiki's beach and hotels, Pearl Harbor and the North Shore surf are the essentials; inter-island flights open up Maui and Kauai.

Best time to visit: April–May and September–October have the best combination of weather, calm seas and lower fares. Winter brings North Shore surf competitions and higher prices; summer is warm and busy with families.
