What a great tour to be doing! Hope the weather isn't too awful :)

I would def recommend checking out a few recumbent stone circles on your travels. Old Keig and Cothiemuir Wood are a brother/sister combo close to each other or another great set is Tomnaverie/Sunhoney/Midmar.

The Pictish stones are incredible, sadly some standing in place are now badly eroded. The Maiden Stone at Bennachie is a good one. I found this link helpful - https://www.aberdeenshire.gov.uk/leisure-sport-and-culture/archaeology/sites-to-visit/pictish-symbol-stones/

Thank You! I'd picked out Tomnaverie, but the others look good - in fact the problem is there are too many - so a little filtering help is perfect. Great link too to the pictish stones - will no doubt get a few in the museums, but again it helps to narrow down the selection a bit. Looks like there is weeks for of visits in the area, not three days. Too many explores to do, not enough days.
