Tro-tros are the second most expensive; however, tro-tros around Accra are around 70 peswaas which equates to about 30 cents. The experience of getting in a tro-tro is something unlike anything in America. Tro-tros are fifteen passanger vans that can be anywhere from fine running condition to almost condemn-able. Most tro-tros only stop at designated junctions or stops, somewhat like a metro bus. The "mate" in the tro-tro will use certain hand signals and call out where the tro-tro is headed when it comes up to the junction. Therefore, it is necessary to know which signs signal which places. The reason it is so necessary is because many people will be vying for the same spots on the tro-tro and there are no lines or order to keep your spot. Thus you will have to push your way in and be aggressive in order to get the tro-tro you want, otherwise you will be waiting a very long time. Once on the tro-tro you will pay the mate and sit in very close quarters with all who are on the tro-tro. For people over 5'7" this will be a rather uncomfortable ride but you will get used to it. The tro-tro is the easiest transportation for the best price.
Lastly, are the buses. They are not much different from metro buses in America so if you have ridden on Detroit's People Mover before then you should be fine with the buses in Accra. The only issue with the buses is that they do not run on any particular schedule so actually getting them is more difficult than a tro-tro. These are the three ways to travel in Accra; all are fun and interesting in their own respects and with practice you can make the most of all your travels before you even get to your destination.
