My partner and I went with our grandson on this tour today and we loved every minute of it.
The tour starting at Greyfriars kirkyard was very informative, with our guide "John the scientist" delighting in filling all the gory details.
Then on to the underground vaults,
with its eerie atmosphere hitting you, as soon as you enter. All feeling very real as you walk around them and are told the history of a bygone time in Edinburgh.
Yet just a few metres above you're head is the Northbridge, with its Streets filled with tourists unaware of what is just below their feet...
