Park at the bike park, follow signs for Gwylfi bike park (on the other side of the valley to afan usual car park)left turn about 1/2 mile back from Afan.
You can then session new section and bike park and ride down final descent on the Wall then ride back up wall to Car
Being fresher for the bike park session
make sure you do Whites @ Glyncorwg new final descent is a blast (still a bit loose in places so watch yourself)
Enjoy
Wouldn’t bother with W2 as there are loads of diversions and extra fire road loops
