Travelling around Guyana is an experiance.
Cyclists tend to be OK, though the 'beep-beep' culture of drivers can be a bit shocking at first. Many drivers honk their horns (as a warning) just before they overtake you - unfortunately that makes it all the more likely you are going to swerve! However, given the number of potholes and lack of streetlights cyclists are advised to bring lights with them from the UK. Male cyclists in particular enjoy the sensation of not having to bump into a large pothole unexpectedly in the dark.
Lots of 4x4 cars as well as lots of old bangers. There is a minimum annual test that cars have to go through. I presume drivers have to pass a test as well. Drivers here are on the whole probably more skilled than their UK counterparts (based on the speed they drive through small gaps) but more dangerous (based on the speed they drive through small gaps).
Travelling on these for the first time can be scary. Instead of people queuing up for buses, the buses queue up for the people. I say queue up for, but its a bit more like 'the bus drivers grab your arms or bags to get up onto their bus'. The reason for this - there is no timetable as such - each bus departs when it has a full load. A full load constitutes anything between the legal maximum of 16 and
Guyana being the Land of Many Waters, is also the land of many boats. For many reasons you may have to travel by boat. They embark and disembark from stellings. There are speedboats to take you across the Essequibo and other rivers.
Port towns include Parika - from where you can journey to places along the Esseqiuibo, including Supenaam, Bartica and Shanklands and Baganara resorts. This is also a market town and a great place to stock up with food on the way back into Georgetown.
Don't travel on the speedboats until at least an hour after breakfast. Make sure you have a lifejacket. Don't sit behind anyone who has just had breakfast, particularly when the waters are choppy.
There is one duty free shop - it seems to sell 347 varieties of rum in assorted bottles, and mounted butterflies in boxes of six. The butterflies look beautiful when fluttering through the Region 7 forests...and strangely hideous in an airport departure lounge. I'm sure there is some UK customs thing that makes it illegal to bring them in to the country as well.
Travelling to the interior and to the resorts is done through small 6-20 seater airplanes. Ogle airstrip is where many flights to/from Georgetown leave. Places such as Lethem, Kaiteur, Lake Mainstay have there own small airstrips. There are other small airstrips dotted around the interior used by geological, mining and forest expeditions.
