You’ll be pretty close to where I live.
From Tarland there’s a lot of nice non-technical riding up into the surrounding hills on landrover track. You could easily cycle to the trails at Aboyne too.
There’s loads of trail/enduro stuff within a 30/45 minute drive at Ballater, Scoly, Pitfichie, Bennachie and Hill of Fare.
If you’re looking to get into the big hills there’s plenty too. The Lochnagar & Loch Callater loops are good and there’s plenty more if you head up to Braemar and into the Cairngorms proper.
Trailsforks is your friend, it’ll show you the heartbreak ridge loop and lots of other stuff.
