Nice camping at Le Beldoire .
Walking distance to the Pas de Souci crags.Great routes between 6b to 8a.Hitching or walking to the main area not impossible at all.There is a little grocery store in the nearest village-Les Vignes.
To get to a super market Millau is the best bet hard to get to without transport from Les Vignes hitching or your bike might be best bet.
