No, you can access but there is a slight detour. From Carrefour go south to Tertre Rouge roundabout, exit direction Paris for 50 yds and then right down the hill behind the bar. Right again under the Tertre Rouge bridge and just carry on and follow the detour. Youll ebd up at the Houx roundabout.
Thats good news, we normally drop of the D323 onto the D338 at Terte Rouge, then go back on ourselves down the little slip lane behind the bar and then under the track and onto the dusty wilderness.
Thanks,
