Cheddi Jagan International Airport
41km from downtown Georgetown, Cheddi Jagan International Airport (GEO) is a very outdated international airport undergoing upgrades at the time of writing, but never likely to be a particularly easy place to arrive or depart from, even when these are complete. There are simple facilities such as a couple of cafes and an ATM, but nothing else.
A taxi is the best way to get to/from the airport. Expect to pay G$5000 to G$6000 for the one hour ride. If you're arriving after dark then it's best to order a transfer to the city in advance from your hotel, as there are not always taxis waiting here.
Ogle International Airport
11km from downtown Georgetown, Ogle International Airport (OGL) is a collection of small terminals abutting an airstrip only large enough for domestic and a few regional carriers to land. There are simple facilities such as a couple of cafes and an ATM here, but nothing else.
Taxi is the best way to get to/from the airport. Expect to pay between G$1000 and G$1500 for the 20 to 30 minute journey to downtown Georgetown.
Bus & Minibus
Economical, cramped and dangerously-driven minibuses to destinations along the coast depart from Stabroek Market and have no fixed schedules (they leave when full). Even getting aboard them can be a harrowing experience as half a dozen touts harass you into choosing theirs.
To travel into the interior by bus, you're limited to overnight services to Lethem, which run the entire way through the country's main road, a dirt track through the jungle. The long, loud, bumpy, dusty journey is not for the fainthearted and involves stopping to sleep at a hammock camp for a few hours (hammock rental G$500), a 6am ferry at the Kurukupari Crossing and several police checkpoints; bring warm clothes, your passport and patience. The buses stop along the main road on demand and pick up as long as they have empty seats (which they often do not – ask your lodging to call and reserve a spot ahead of time for any stops besides Lethem and Georgetown).
