Ghana is a safe country, but you have to be careful whom you deal with. Trust your own instincts when dealing with people. There are many people out there that wouldn't physically harm you, but wouldn't mind taking advantage of you. Most taxi drivers overcharge, so always negotiate with them.An hour taxi charter is 25 Ghana Cedis, so use this amount as a tool to do your calculation for short trips. For the police, you dont have to worry much about them, because they do not bother drivers a lot these days. If you happen to live in an area that is pretty much busy, you dont have to worry about a thing go for your walk! Good luck on your trip to Ghana and enjoy your stay.
