Skyline has been cut short massive, the diversion back makes no sense and actually misses some open and rideable sections (fast forward etc..). If doing it i would ride the trail as marked but when returning on the bridleway i would take a left down passed the end of grenada and onto fast forward and joyrider, which is what the trail should do instead of that bullshit boggy brideleway which comes out at the same point!
If you have a GPS map take your phone and ride the whole thing, its a bit overgrown in parts but makes for a quality ride. None of the original (apart from the final descent at the moment) is unrideable.
Personally if you wanted a biger ride its a good option to W2 as Skyline is all of current whites and more.
I ride up there often so know whats open and whats not.
