Id agree with Davey Boy, its pretty dull and the black route is really easy, you could do it on a bmx. Certain parts of the black are good fun since they flow quite nicely but theres far too much of it that feels like your riding around Centre Parks forest village
I'd also agree that Grizedale is better, at least it feels like your out in the wilds a bit and doing 'properish' mtbing.
Went there yesterday for a pre work blast
It's very short - took me about 1¼ hours to do all the red & black, so you'd need to go round 3 times to make a day of it
The black bits are great fun & very fast
The long fire road climb at the start is boring
I found myself losing interest on most of the red
I didn't have time to try the café but it looked nice
All in all not a bad sneaky pre-work ride [it's good to get paid to ride 😉 ] - if I was to go back, I'd have to look at looping back to the black bits a bit easier than following the markers back round
The official line is that the only access to the forest that is permissive is Offa's Dyke path, all other bits are private land so out of hours when the centre is shut you are trespassing....
