I've been reading many trip reports that cover The Gambia and Senegal in a single trip, but very few go into detail on which routes they are taking.
We will only have 2 weeks and want to focus on The Gambia, but also include a 2-3 day visit to Nioloko-Koba National Park to the east of The Gambia in neighboring Senegal.
I've already made the assumption that reaching it by public transport is a no-go, and that we'll need a driver.
Trying to plan and consider what routes to take or how to schedule our transportation within 2 weeks I am looking to get an answer to the most reliable, quickest route to drive from central The Gambia to the Nioloko-Koba National Park (entrance). Based on actual experience or real knowledge of the area.
