Do any of you know of a good natural route in the Lochinver area of Sutherland, NW Scotland ?

And have you ever ridden it ?
Reason i'm asking that is because of my questionable fitness right now.

I'm going up there for the Easter holidays with the Family.
Staying with friends, and a wee trip to Golspie may be on the cards. But if it doesn't work out, I'd love a couple of natural trails up my sleeve for a blast.

Ideas very welcome…
