The Aeropuerto Internacional Jardines del Rey, Carretera a Cayo Coco (tel. 33/30-9165; airport code CCC), accepts international flights from Canada, Argentina, and the U.K. There are twice-daily domestic flights on AeroCaribbean (tel. 33/30-9106) from Havana for CUC$108.
The hotels offer airport pickup services for clients. If you have not prearranged transportation to your hotel, there are usually a couple of state-owned taxis hanging about. The fare from Aeropuerto Internacional Jardines del Rey is about CUC$10-CUC$15 to Cayo Coco and CUC$15-CUC$25 to Cayo Guillermo.
If you're traveling independently to the cays from within Cuba, getting there on your own without a rental car or legal taxi is complicated. The only bus services that travel across the checkpoint are those belonging to official tour operators, such as Cubanacán, Cubatur, and Havanatur. All of these operators offer package deals and transportation options to the cays from all of their major operational points, including Havana, Santiago, Varadero, Trinidad, Santa Clara, Cienfuegos, and Camagüey.
A more complicated way to the cays is to take a Víazul bus (tel. 33/22-5109; www.viazul.com) to Ciego de Avila, and then hire a taxi all the way to the cays for CUC$60 to CUC$75. All Víazul buses on the Havana-Santiago route stop in Ciego de Avila. The fare is CUC$27 from Havana, and CUC$24 from Santiago. Make sure you hire a state cab, as a driver with his own car is still not allowed to transport foreigners to the cays. The nearest town to the cays with legal casas particulares is Morón.
To drive to the cays, head north out of Ciego de Avila toward the city of Morón, and follow the signs out to the cays. You can pick up a taxi in either Ciego de Avila or Morón, the two nearest cities of note. Call Cubataxi (tel. 33/26-6666 in Ciego de Avila and 33/50-3290 in Morón). A taxi from Trinidad costs CUC$100. A taxi from Morón to Cayo Coco is CUC$45 and to Cayo Guillermo CUC$55-CUC$65. From Ciego to Avila to Morón is CUC$15. One has to pass a guarded checkpoint with a toll each way of CUC$2 to access the pedraplén that bridges the distance between the mainland and the cays. Remember that if you travel from Morón to the cays for the day you will need to show your passport at the check point. There are rental offices in Morón and Ciego de Avila.
