As usual, leave Deauville going in the direction of Saint Arnault (D278). 

Turn off to the right exit at the roundabout onto the D27 taking the direction of Tourgeville and Cabourg. 

Keep on this road for quite a while to Vauville and turn left unto the D281.  

Stay on this road until you see the exit (again a left turn) to the D118.

Keep on this all the way to Beaumont-en-Auge.

Once at the top (90m) revitalize yourself with some cold cider at the cafe near the statue of the neighborhood's most famous mathematician, La Place.

Don't forget to admire the view before swooping down the D58 (opposite the D118). 

Keep going until the signs show you the way back to Deauville along the D278.
