Hi, I spent 5 months travelling and working in Ghana, and not once did i feel unsafe. I found it to be a charming country, maybe not so dynamic as some other African countries when it comes to scenery but the people really were the most friendly and welcoming people i have ever had the pleasure to meet. I was by myself most of the time, local buses and tro tros and again never once had a problem. Also paid local prices (most of the time)which was one of the few countries i visited which did not have the foreigner price V local price. I spent most my time in Kumasi which was very safe although night time walks around town by yourself are not recommended. But visited the volta region, coastal areas and the north, all good. Accra has to be the most difficult city to get around due to the traffic,some great resturants etc eg in Osu Venus does great lebenes food and good bar, also mama mia if your missing a great pizza. I have not doubt that you will enjoy it, your worst enemy will be the transport/road accidents rather than crime related. Safe travels.
