this place is nice to stay at, freindly owners, nice food etc, its also secluded and away from any other houses. so no distractions and great views.
and its kinda in the center of where all the stone circles are.
its in Mintlaw, nearish to peterhead/ Fraserburgh. and about 40 mins to Aberdeen.

ive stayed there before, but that was before i knew about all the stones there. i visited all the ruined castles. which there are loads.
