Wanderlust World Wanderlust World The great-circle (over-water) distance from Crescent City, California to Honolulu, Hawaii is approximately 2,400 miles (3,862 km).
This measures from California's northwestern coastal tip (Del Norte County) to Oahu — roughly the same as Los Angeles to Chicago, but entirely over the North Pacific. No commercial shipping lanes or flight paths follow this exact line; great-circle routes from West Coast to Hawaii arc further south.
