Lac Vert (Commune de Canéjan (33610)) walks

A unique trail in France offering a journey through the history of our universe! The Path of Time: every metre covered represents 1 million years, and the 13.8 km of the Path of Time retrace the 13.8 billion years separating us from the Big Bang. This project was designed by the University of Bordeaux and its Bordeaux Astrophysics Laboratory (LAB) as part of the “Science with and for Society” initiative. It passes through the towns of Gradignan, Pessac and Talence, as well as the University of Bordeaux and the University of Bordeaux-Montaigne. This route also follows the GR® Bordeaux Métropole trail markings for several kilometres.

A unique trail in France that takes you on a journey through the history of our universe. The Path of Time: each metre travelled represents 10 million years, and the 1.38 km of the Path of Time retraces the 13.8 billion years that separate us from the Big Bang. Project designed by the University of Bordeaux and its Bordeaux Astrophysics Laboratory (LAB) as part of the "Science with and for society" label and in partnership with the city of Talence.

This route takes you roughly along the small River Peugue from the border between Bordeaux and Mérignac to its source in the Bois de la Princesse in Pessac. It is a well-shaded route, suitable for all seasons except during very hot weather or rainy conditions, and can be completed by mountain bike or hybrid bike (the terrain is either tarmac or clay). It is also possible on foot, but a little tedious in places (Rue des As and Rue Socrate).

Discover the hillsides on the right bank of the Bordeaux metropolitan area as you pass through numerous parks, each with its own unique features (lakes, fountains, ponds). You’ll also enjoy remarkable views of the right bank.
