The route below will not indicate many navigation systems. But it bypasses the hustle and bustle of Paris and it's cheaper. Because, among other things, the "autoroute de l'arbre" is cheaper in terms of tolls.
From the Netherlands you drive towards Paris. Just past the tunnels of Charles de Gaulle airport is the N104/A104 exit. This is the outer ring around Paris, also called route Francilienne. Follow this road until the A6 exit towards Lyon.
Then take the A6 towards Lyon until you reach the A77. This is the road you want to drive: the autoroute de l'arbre. A nice highway with little traffic. Nice detail: the different tree species are indicated along the side of the road. You drive all the way out of the A77. It eventually turns into the N7 to Moulins.
From Moulins you can take the fast N79 to Montmarault and then drive via St Eloy les Mines to St Gervais d'Auvergne. During the day it is worth taking the nicer route via St Pourcain sur Sioule, just a little further after Moulins (N7) the D46 which then becomes the D987 (Chantelle, Bellenave) all the way to St Gervais d'Auvergne.
Our holiday domain 3Etangs is located in the small hamlet (with four houses) of Le Fal. This is about 2 kilometers before St Gervais d'Auvergne, so keep an eye out for our 3Etangs sign on an old carriage on the left-hand side of the road.
