You could start at High Cross missing out the Oxen Fell loop but you would also miss out on the drop back into Coniston or,
you could still start in Coniston and climb the final drop at the start and carry on the fire road to Parkamoor again missing out the Oxen Fell loop but keeping in the final drop or,
you could road climb from the youth hostel to High Cross (again missing out Oxen Fell) but use the final drop to Coniston as your route back to the hostel.
The Oxen Fell route is a good warm up but it doesn’t really do that much. It’s fun trying to climb to the slate workings when it’s wet but other than that I would drop that section to make it shorter.
There are other shorter, easier and ‘legal’ (don’t get me started) ways to go over Claife that would cut down the route a bit more.
When you’re on the forest road from High Cross keep an eye out for the wooden sign directing you to Parkamoor, it’s a wooden effort on the left directing you to leave the forest road on the right through the trees. It’s easy to miss but the trail goes straight ahead cutting through the trees as the fire road bends to the left.
The route through the forest from Force Forge is along a BW and is fairly well way marked and there is some good technical ST in there. The start is PAST the forest trail carpark in a smaller layby/entrance to a forest road and the BW is to one (left) side, you’ll see it on Google Earth.
Satterthwaite is a good halfway place to stop being a small Hamlet with a pub and a cafe (you need to take the very small country lane after the church on the right to continue the route)
The route out of Hawkshead is literally between the houses and one to Google Earth so you know where it is. I cycled up and down the back streets for an age trying to find it.
