A typical round-trip cruise to Hawaii from the U.S. West Coast (Los Angeles, San Francisco, or San Diego) takes about 14 to 16 days. Because Hawaii is located roughly 2,500 miles from the mainland, the journey begins with 4 to 5 full days at sea before reaching the first island. Once in the islands, the ship usually spends 4 to 5 days hopping between ports like Honolulu (Oahu), Kahului (Maui), Hilo (The Big Island), and Nawiliwili (Kauai). The return journey then involves another 4 to 5 days at sea back to the mainland. For those with less time, some cruise lines offer 10-day "one-way" sailings that end in Honolulu, requiring a flight back home. In 2026, these cruises are popular for travelers who enjoy the "resort at sea" experience as much as the tropical destinations themselves.
