By plane
The International Airport, Henderson, is 7 miles east of the capital, Honiara. Scheduled flights depart from Brisbane, Australia about three times a week. There are also flights departing from Vanuatu, Fiji and a handful of other South Pacific neighbours.
By Sea
Cruise ships occasionally visit Honiara.
It is also possible to travel from southern Bougainville in Papua New Guinea by boat into the Solomon Islands western province, as locals routinely travel between the Solomons' Shortland Islands and Bougainville.
