No archery thread. All the indoor places we shoot have been shut most of the year ?
Where to go in Aberdeen really depends on what you want to do.
Kirkhill forest/tyre bagger is OK. The old Deeside railway is fine for some miles. You have Tarland Trails if you want some practice without covering much distance.
I did bennachie on my old mtb but there are sections I carried the bike and I wouldn't want to do that with an emtb. Coming down from mither tap to the rowan tree was fun (started back o Bennachie).
Forum says I'm in Notts but I spent 30 years up in Aberdeen after being born there ?
Going further but organised you could try glenlivet.
