There’s a dispatch office at the airport; you can also flag down taxis on the street (look for license plates with a “TX” tag). Rates are fixed by the Aruba Dept. of Public Traffic (i.e., there are no meters; the rates are set by the government and displayed on a chart), though you and the driver should agree on the fare before your ride begins. A maximum of 5 passengers are allowed in a taxi. Add $2 to the fare after midnight and $3 on Sunday and holidays. An hour-long island tour costs about $45, with up to four people. Rides into town from Eagle Beach run about $10; from Palm Beach, about $11.
The taxi dispatch office is located at Pos Abou 41 behind the Eagle Bowling Palace on the Sasaki road. Phone +297 582 2116 or +297 582 2010.
