Positivo98 days pure walking with my best friend gerard was of my best experiences!!
This 8 is because of a 9 in the french alps, an 8 in the vosges and ardennen in belgium abd a 7 in luxembourg, pays lorraine and parts if the netherlands
It is special because you walk to the sea and walk through beautiful national parks!!
PositivoHighly recommended! GR5 is most excellent Alpine crossing, from Lake Geneve to Nice and great especially for campers. All the pros and cons, detailed daily information, free camping guide and the eBook: Alone Through the Alps, can be found from my blog at: https://longdistancetrail.wordpress.com/trails/2013-gr5-the-grand-traverse-of-the-alps/
NegativoOnly minor things bothered me, like the language barrier (French). Time to times I would have liked to meet more like-minded long-distance hikers.
