France is a paradise for walkers, with a vast network of walking tracks, marked with distinctive colours and symbols.
Long-distance tracks across France are called Grandes Randonnées (GRs), whereas tracks that loop around through a particular area are called Grandes Randonnées du Pays (GRPs), and shorter day walks are called Promenades et Randonnées (PRs).

Different colours are used for these three types of walks – red and white for GRs, red and yellow for GRPs and yellow for PRs – and there are three symbols: “straight-ahead”, “turn” and “go back – you missed the turn!”. Various other colours are used for local walks.
A good website for general information about most GRs and GRPs is GR-Infos.
The map below is very useful when choosing a walk, as it shows all the GRs and GRPs. When we discovered this map (which we have greatly modified to make it more walker-friendly), it was a revelation, and we wished that such a map had existed in 2002 when we first started walking in France.
It can be slow to load but definitely worth the wait.
