This comment is hurtful, a view of a clear cut in a forest is more sad than beautiful… behind this view are hundred of thousands / millions of insects that are killed, death and loss of habitats for numerous small and bigger mammals … trailing in a natural environment is good when it brings you closer to its needs, more aware of its fragility, what you call beautiful is a loss of biodiversity for human productivity purpose

What is to be remembered from this route is the passage through the Carnelle forest. However, there are too many roads on the Isle Adam and along the Oise. No particular difficulty.
