Renting a car can be cheaper than public transport if two or more persons are traveling together and you plan on moving around a lot. Both companies and roads can be dodgy; check the cars thoroughly, and know how to put on a spare tire. Most companies have desks at the airport.

Local SMTC buses (for schedule 25-49-29) service the region around Cayenne and Montjoly’s beaches (US$1.50). There are limited routes and buses don’t run on Sundays, so you’ll probably need taxis.
Taxis have meters and charge a hiring fee of US$1.80 plus 90¢ per kilometer (US$1.30 from 7pm to 6am, Sunday and holidays). There’s a taxi stand on the southeast corner of Place des Palmistes.
