Lihue Airport is a small, semi-open air airport and the major point of entry for the island of Kauai. There are a small number of flights directly between Lihue and the mainland but a majority of visitors will have to change planes in Honolulu to get to Kauai. If you are flying to or from another Hawaiian Island you will need to change planes in Honolulu to get to or from Kauai. Though this airport is small you will find many of the conveniences of any other airport. There are also advantages to flying in and out of this small airport: baggage can be collected at baggage claim more quickly than at a larger airport and the people working here are so nice making it easier to get individualized help. Another plus, all the rental car agency desks are found directly across the street from baggage claim, in case you want to search out better deals face to face and counter to counter and the cars are easily found right behind those same counter so no shuttles. It’s easy in, easy out, close to town and Lihue is pretty central so it makes it easy to get away to the north or south side of the island in no time at all.
The best way to get around Kauai is by rental car, as many of Kauai's best sights can only be reached by independent transport.
Kauai has a bus system, it goes from Hanalei to Kakeaha, they have stops all along the main highways, but they aren't well marked.
