In reply to CantClimbTom:
As you say there might be some wins with the new track. It might encourage people to try a different route up Snowdon from Llanberis other than the usual Llanberis Path.
Somebody walking up the road from Llanberis to get to the start Llanberis Path will reach the start of the new track first (just past the cafe). I guess there might be a sign saying ‘Snowdon via Bwlch Maesgwm/Snowdon Ranger Path’ (and perhaps a notice board/map explaining the route) and thereby encouraging people to try it. Previously the indistinct grassy path that left the road wasn’t signposted and rarely used. It’s about 2km further to the top of Snowdon than the Llanberis path and apart from the steep section on the Snowdon Ranger path it’s steady going so shouldn’t be a problem for most walkers. Some might be tempted to go over Moel Cynghorion from the bwlch which is worth the extra effort.
All in all, I can see it becoming a popular route to the top of Snowdon, with a return down the Llanberis Path, that will open up a new area to many but which may spoil an otherwise quiet valley.
