Pretty much every way you can see on the map goes and is really good, from Warnscale you could skip the road ride to Gasgale by going back up Honister onto Dalehead, then either down through the mines or carry on towards Cat Bells, that’s a cracking descent.
Hindsgarth and Scope End is another pretty decent way off too.
Rigg Beck is ace, but I reckon it might be more affected by the recent weather and it’s not as good as your other options.
If you don’t go Dale Head, Gasgale is the easiest way up, assuming it’s not too messy after the rain. From there the best descent is off Causey Pike, you can’t ride the top section, but once you get to the start of the scree it all goes. Bear left halfway down rather than going off the end of the hill.
The run into Coledale is a top top descent, very fast and rocky, less technical than the others.
All routes off Grizedale Pike are great, but the ridge that brings you out at the bottom of Whinlatter Pass is one to do on a good day, with your A-game and with some friends, it’s the riskiest option.
