You want to try climbing in there. Some of the fiercest slate climbs anywhere. b****r all for protection apart from some strategically placed bolts.
This one might be a bit harder....
Yay, at last, we've got a toughie!!!
I'll post some clues here at random intervals until someone surrenders or guesses it.
1) Julia Bradbury woz ere.
2) Alfred Wainwright woz ere.
3) Bang in the middle of some of the best mountain biking, fell walking and fell running country north of M62. (Is there anything worthwhile south of the M62?)
4) Close by the main road route to the "honeypot" town in the area, but the grockles and innits never go more than 200 yards from the car park so miss things like this.
5) Connected to a very old industry, with origins possibly as far back as Roman times.
Oh dear, looks like we've got a sticky here!! Next clue
6)A very well known bridge near here, which gives it's name to the general area.
7) If OP has done the research for his upcoming holiday properly this should be close to the top of his list.
