Warm clothes and waterproofs - and tea and cakes
If you want 'tourist attractions' it generally involves a bit of a drive.
If historic castle stuff interests, there's Corgarff and Kildrummy. Nearby Glenbuchat is closed due to unsafe masonry. (Sadly, North Glenbuchat Estate appears to be associated with raptor persecution).
Shorter walks (perhaps if with kids) - up Chapel Brae, past the duckpond and around Morrone Birkwood. To the mast at the top of Morrone is longer than it looks.
Walk through the woods up to Craig Choinnich or around (look for the Lions Face, then continue round to little cascading falls).
Up Glen Slugain - note if parking at Keiloch, the first bit is a slog over tarmac, better to ride this.
Taking bikes is a good choice - various rides, from Linn of Dee to White Bridge or to Derry Lodge.
Walk up Glen Ey.
Lost Art Gallery, the sign at Lost is ideal for comedy photo opportunities
If howling, horrible weather then books and games (and tea and cake).
