Getting around the Marquesas is difficult. The valleys are isolated, making it virtually impossible to tour by road, and only the main settlements have sealed roads. Some settlements have no landing stage and rough seas make landings challenging to say the least. The introduction of helicopter shuttles within the northern and southern groups has improved inter-island transport. Héli Inter Marquises (92 02 17; email@example.com; Taiohae, Nuku Hiva) does convenient but costly charters on Nuku Hiva and flies three times a week to 'Ua Pou, and to 'Ua Huka on demand.
Inter-island travel is via Air Tahiti, helicopters, bonitiers and the cargo ships Taporo IV and Aranui. Nuku Hiva and Hiva Oa are the hub islands; travel between these two is regular and reliable, but further afield can be more difficult. Don't expect things to go to schedule.
