It’s split into 2; Fineshade & Wakerley Woods.
Fineshade Woods has a family trail that’s good for a warm up with some “skills” loops on it; most of which are likely to be beneath the level of most people on here & not particularly well thought out, but the last 2 or 3 are quite good fun and got some giggles from me.
It also has some really nice XC type paths, but they’re for walkers only, so avoid on sunny weekend days.
Wakerley Woods is a bit more like it really 🙂 Decent XC type trail that will sadly suffer quite badly from being ridden in the wet. It has a couple of really nice (but short) swoopy bits and some challenging climby sections. Not bad for the small amount of money that’s been spent on it.
Also some half decent random offshoots & illicit trails exist to bulk out the official trail – and some really shit jumps that should be avoided at all costs 🙂
Poss not worth driving more than 1 hr to get to, but if local then better than nothing.
