The GR 5 is one of the Grande Randonnée (or GR) network of paths and trails. It now starts in the Netherlands and crosses Belgium and Luxembourg before traversing France to end in Nice. However, a recognised variant is typically considered a preferable finish along the GR 52 to Menton since it stays in the high mountains rather than dropping into farmland and suburbia for the final few days.
Originally, the section through the French Alps from North to South was known as the Grande Traverse des Alpes and runs from Lake Geneva to Nice. That section eventually became the original GR 5 before later being extended northwards.
GearAs with all trekking: pack light!
- Lightweight walking shoes
- Wide brimmed hat and sunscreen
- Light weight waterproofs
Along the Alpine section water is generally readily available and the drinking fountains typically considered safe for foreigners as well as locals. If following the variant finish along the GR 52, for the last day into Menton, you must start with all the water you need for the whole day since there is only one spot that might have water and it is somewhat unreliable and used for watering sheep.
Camping and refuges
There are numerous refuges and gîtes along the Alpine section of the route, offering comfortable accommodation.
Camping opportunities vary greatly since the route covers such large distances. Within the Alpine section; there are places where camping is forbidden and places where it is permitted but only after a certain time in the early evening (such as the Mercantour Mercantour National Park). Carrying cash is advisable since most of the more remote accommodation will not take cards.
It would take many maps to cover the entire trail. For the Alpine section the French TopoGuides series 504, 530, 531 and 507 contain 1:50,000 scale maps of the whole route (and lists of accommodation, but in French).
Walk early, to avoid storms later in the day.
