Getting from HNL to Waikiki, downtown Honolulu and nearby areas

• Rideshares and taxis: Both rideshares and traditional taxis are available at the airport and work well if you're heading straight to your hotel.
• Hotel shuttles: Some Waikiki hotels offer complimentary airport transfers, so check with your hotel before you arrive to confirm availability and timing.

What’s the best time to travel from San Diego to Honolulu?

• Whale watching: Visit between December and early spring for the chance to see humpback whales just offshore—a seasonal experience that's unique to Hawaii.
