Y Sap is no longer to be seen but thanks to Richard Dunning's purchase of the crater, Lochnagar is still very much in evidence.A definite must see if in the region.
This is an excellent website well worth exploring

Of the crater Richard Dunning writes:
I have visited the site several times and each time I feel as he describes.People who stand on the lip for the first time, including the thousands of young people, instinctively understand the fearsome power and destruction of modern warfare and, in reading the many evocative memoirs of the soldiers themselves, the terror and vulnerability of those who experienced it.
