Black Combe is always good. Best to go up at Whitbeck on the coast road, mirror the road going north and then turn up with the fell wall to its highest point, then cut up right to the top, and then down to Whicham Church and back round to Whitbeck. All doable tho I always wimp out at a couple of bad steps at the beginning of the final section down to the fell wall gate above the church.
If you wanted to make it a longer day you’d need to incorporate a bit of road but there is a dirt track that climbs out of Bootle up to the top of the Corney Fell Road. There is then a track off that fell road about 1km south of the top (very bog grass no track-track at first, so best ridden downhill) that takes you down past the Swinside Stone Circle, then you’d be tarmac (take the back roads, they are v quiet) back to Whicham.
Great Gable……….from walking up there I think…LOADS AND LOADS OF HIKE A BIKE… I’ve not done it with a bike, but I have gone up from Wasdale and over to Langdale with a bike, and that was LOADS OF HIKE A BIKE
