Many users recommended renting a car as the best way to navigate the Dordogne due to the lack of public transportation. It was noted that car rental agencies are available, and having a French driver's license or an International Driving Permit (IDP) is necessary if your license isn't in French.

For those open to cycling, some posts suggested renting bicycles as a way to explore. There are green routes along the Dordogne and Céou rivers which provide scenic paths suitable for biking. This could be a viable option for those looking for an active way to see the area.

Several travelers advised that thorough preparation is crucial if you choose to rely on limited public transport or bicycles, due to the rural nature of the region and the sparse transportation infrastructure.
