Transportation - Get In
Plane is the only realistic choice. There is only one airport, Airai (ROR), on Babeldaob.
Visitors can take United Airlines' daily flights from Guam (~$600), which has connections to Japan and the United States, as well as directly to Manila, Philippines.
Delta Air Lines launched daily service to (ROR) from Tokyo-Narita (NRT) on December 2010 with connections on to many destinations throughout Asia as well as to its hub cities in the US (including Hawaii).
Asiana Airlines currently operates regularly scheduled flights from Seoul's Incheon airport.
There are also chartered flights direct from Taipei, South Korea, and Japan on a variety of operators.
Possible but not very easy.
Transportation - Get Around
Taxi and rented car. Lots of local taxis. If you rent a car, be prepared to drive slowly on some bumpy roads. Both left and right hand drive cars are present in Palau, which can cause some confusion. If you drive south, to Ice Box Park, please note that the facility behind it is a sewage treatment plant. Any other diving will be from a boat, after an hour or more ride and cost around US$150 for a two tank dive. There are no dive spots or beaches on the main island - Koror. The road north was recently paved and is very nice... once you get past the airport.
