The boulder fields, flats, ponds, the strange and phantasmagorical rocks, the large forests and the moors are among the many varied and contrasting landscapes which are part of the attraction and reputation of the Fontainebleau massif. Behind the natural beauty of these landscapes lie both an ancient and a more recent history that led to their shaping.
The sand dunes, the Montagne de Trin, the Marais de Larchant and the peat ponds of Franchard are among the 23 sites commented on and suggested to walkers wanting to learn about the history of the rocks and landscapes that form the Fontainebleau massif. They will allow you to discover and understand the intimate mechanisms that take place "under your feet" and that shape these landscapes.
The aim of the guidebook is to show that geology is not difficult, that often there is no need for geological knowledge, and that it is first of all an exercise in observing, understanding and applying a bit of common sense. The guidebook is intended to exemplify a recreational and educational scientific approach.
