The airport is located on Gravina Island and visitors can get into Ketchikan by ferry or water taxi. Once in town there is a municipal bus service provided by Ketchikan Gateway Borough Transit operating hourly every day of the week. A seasonal, complimentary Shuttle Bus runs a 20-minute circuit around downtown Ketchikan, which is very useful for tourists. Taxis can be ordered or hailed on the street. Cars and bicycles can be rented in town, but those hiring cars should note that parking can be expensive as permits are required.
