La Bertinière

We visited this site in August 2010, and there seemed to be no problem accessing it. After taking the D18 west out of La Sauvagère for about a mile we came across this sign, or rather the back of it ,as it's only really visible travelling towards La Sauvagère. We drove down the small lane for 0.5k as the sign said and came to a small parking area. The passage grave was over the gate and along a wide gravel track. There were no signs to suggest that we should not be there.
