In reply to jebel_andy:
Probably Number 65 bus is closest. You can try planning a journey here:
http://www.travelsouthyorkshire.com
put "Froggatt Edge, Hope Valley" as destination
if you go to google maps and put "Froggatt, adj Stoke Bar (Unmarked)" as destination it will show you where you end up.
I'm not sure where the climbers hut is in relation to the bus stop unfortunately.
