I hadn't thought how hard this would be until I really tried to pick one!
After a bit of mental sifting past so many fantastic trips, I think I can only narrow to a top two...
The whole Orkney trip last Feb, just an amazing all round experience - very little brand new to me but just blew my mind in many ways!
And (part of a busy day visiting other sites with a good friend) a stand out moment stood in Tomnaverie Stone Circle with the light doing amazing things, birds flocking overhead, feeling cradled and in total awe.
