Thanks archaeoroutes good to know although I'm not sure where I'd get a list of easy fells for there from.
From Dent Station there is Great Knoutberry Hill. A round trip to include Arten Gill is well worth it for the waterfalls and other views.
Or follow the railway south to Ribblehead - a great walk through an impressive pass with great things to look at.
From Settle you could explore Langcliffe Scar. Lots of things to look at, especially the cave mouths
Once you've got a bit more confident, there's Penyghent from Horton in Ribblesdale. Some steep bits, but nothing desperate.
And of course Ingleborough. Perhaps explore the limestone pavements on the first trip and take a look at the way up. From Horton via Sulber Nick it's a steady plod uphill but with amazing things to see and a great sense of achievement.
