In reply to Christine:
1) yes.. straight up the zig zags.. over the iron bridge, right, follow that incline up to the main byway.. through the kissing gates then up the huge incline just to your left.. with paving slabs on. Every time it looks too steep or broken, look out for broken steps on the LHS.. follow this until a big swinging corner.. or up the incline again.. then up the there to the top gate. Then up another incline and trod diagonally up right to the top road.. then look for a winding shed back left.. then straight up.. you should pop out 100 yards to the right of Elidir Fach...
But basically just go up up up..
2) Capel.. god no... its a bog.. you follow the boundary fence.. its called boundry ridge. The PB is very unpathed, think trods at most generally, its why its harder than the BG.. but that section especially, and early on hebog is very rough, complicated, hard to know which summit is which. I did that at night in a blizzard on my winter round and was constantly falling through the ice into deep bogs and had a hell of a night there..
3) Lagoons.. or on the road say in the estate..
