I live in Caton and regularly ride the hills around Littledale & Roeburndale. I have a liitle loop that goes up a bridleway at the top of Brookhouse village onto Caton Moor and then back down via the road and access track by the windmills. Approx 10 miles in all.
As stever says the Salter Fell route is ok, but not technical. Good for an xc type blast, out and back.
There are some BW’s around Kirkby Lonsdale which head out towards Casteron & Barbondale.
The best local riding is at Farleton Knott near BUrton in Kendal. There’s a good 2 hour ride around there that i can supply a gpx file for. Its about 9 miles from Caton so could be ridden to and from aswell.
