In a post a while ago, there was a good summary of crags you could get to from Leeds by public transport (

A collated list is below, thought it would be good to repost for people. The original post was 5 years ago so some info may be wrong now if bus routes have changed etc
Baildon - train to shipley, then 25 minute walk
Caley - X84 to otley, get out when you see boulders on your left
Chevin - X84 to otley, get out when you see gate on your left and 10 min walk
Ilkley - Train/Bus to ilkley, then 20 minute walk to the crag
Heptonstall - Train to Hebden Bridge then a 35 mins walk to the crag.
Crow's Nest Wood Quarry - Train to Hebden Bridge then a 5 mins walk to the crag
Almscliff - train to weeton then 25 min walk
Hetchell - bus to Bardsey then a 10 minute walk

Chew valley crags - train to Greenfield station.
Shipley Glen - Train to Shipley
