If your passing, worth a look in. We live relatively local and use it all the time. Best route round is, park in the main car park and go up and do the black (the rebuild isnt all finished, but still fun). Drop down to the forest drive and turn right. Dont turn left up the little stone brige, but carry on past the second car park (normally used for horse boxes) and take the fire road on the right through a metal gate (normally open) to do the red short cut Yorkshire has give (save the long fireroad climb).
This is the ‘compact red route’ without the black at the start: Strava
As you drop down to the fireroad from Section 13 (the one by the DH tracks) there is lots of off piste stuff in the woods. In general, the built stuff all holds up pretty well, though there are currently a lot of breaking bumps in Section 13.
There isnt really another trail centre close by.
