You are free to travel on your own. On weekends and also during vacations. You could also plan a travel month at the end of your stay where you have time to explore Ghana/Africa. The only recommendation is for volunteers to stay in their project for the first 1-2 weeks after arriving in Ghana for the first time before traveling. Also, due to poor road network, we recommend traveling long distances in the day to avoid getting stuck in during bus or “trotro” breakdown.
