MTB near Aberdeen

My little sis' moved to Aberdeen a few months ago, and I'm thinking of visiting her and any nice MTB trails nearby. Anyone know of any, and would maybe like to go for a spin/pint when I'm up?

You will be Nr Aberdeen! Fuck going to a trail center buy a 1:50,000 o/s map and go exploring for fuck sake!

I'm looking for tips, wherever they may be. Happy to go off-piste, but I was looking for some pointers.

You can cycle almost all of the way to the top of the most Easterly of the Munros, Mount Keen, from the North (I've walked it, not biked it)

I know some folk who take to the hills around Aboyne if thats not too far out of town for you?

No idea. I'll find out exactly where sis lives.

I'll ask my flatmate when he's back up from home! He goes riding like two or three times a week and is constantly telling me of all the gnarly trails he hits up!!

I wrote out another reply to this last night but obviously didn't submit. Sorry for being miserable.

I recommend getting this book
Exploring Scottish Hill Tracks: Amazon.co.uk: Ralph Storer: Books

It has several good route close to Aberdeen.

No worries, you weren't miserable. I was just looking for some insider info. Went to the peak district last year with an OS map and had an awesome time, but I thought people might have some favourite routes. I'll check out that book, thanks.
