Give several days to get to and from and bring more triple what lonely planet says in the W. Africa guide. It is time consuming to get there, the poda-podas only leave when they are full, as is the way in all of W. Africa. It took me over 2 days to get there, and it is very difficult to get back because it is a small town you are trying to leave from, arrange for transportation before hand, or make it an adventure and find your own way back. I rode a motorcycle with a 17 kilo backpack on for 2.5 hours.
