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 $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.
