Couple of things worth doing - Maritime Museum , Art Gallery is not bad depending on what visiting collection they have in.
It has a new Shopping Centre built two years ago with large Cinema complex- called Union Square, the main high street Union Street is pretty impressive on a sunny day- and can be quite good smart car spotting territory.
Stonehaven which is further south and neighbouring Dunnochter Castle where hamlet was filmed is picturesque.
when we have visitors up the following seem to be favourites - Royal Lochnager Distillery ( next door to Balmoral) , Craithes Castle at Banchory , Loch Muich - on the Balmoral estate . Most of these are all just of either the North or South Deeside Road.
Are you bringing the Zed if so there are miles of great driving roads around Braemar .
