In reply to trailertrash:
When I visited last there was 1 tree which was kinda blocking the small trod up the hill shortly after leaving the car park but easily got around, above that the stile has been broken for some time ( years!?) but you can go underneath it.
Never went past Northern Soul / Titanic Arete so not sure what it's like to get to the Gruffalo / Daze of the Weak etc. from there ( much better to access these boulders by continuing along the main track for some way before heading into the trees).
