Some rather harsh comments above!
It does have drainage issues in places, but the team down there have improved it greatly over the past 18mnths and there are jet washes on site to clean bikes and showers for riders….. Its winter people you gonna get muddy!
The singtrack route is a good laugh, not massivley technical but ridden at speed can be quite a challenge, there are no huge hills but a couple of steepish ups and downs to keep you entertained. I also think there is a new section with a couple of smallish drops (although not ridden myself)
All in all its worth a visit, I’m only 30mins up the road by car and regularly do an early run down on sat to knock a couple of laps. Yes Leith Hill is better, but you’ll be hard pushed to find 15K of uninterupted singletrack else where in Kent…..
