After my less than tranquil 3 peaks walk last year (mentioned in the other 3 peaks thread) I devised an alternative route that would miss out some of the busier stretches. (The climb of Ingleborough from Chapel le Dale in particular often seems to be a bit of a procession).
This one starts and finishes at Ingleton, though obviously you could start anywhere on the route.......
1. Climb Ingleton via Crina Bottom.
2. Descend to Horton, either via the "classic" route, or via Little Ingleborough / Gaping Gill / Long Scar / Sulber.
3. Penyghent to Ribblehead and Whernside as per the classic route.
4. From the top of Whernside, instead of dropping down to Chapel le Dale, walk straight down the long ridge to Twisleton Hall.
5. From here you could finish via Thornton Force and the River Twiss. (Or down the other half of the waterfalls walk, the River Doe).
Alternatively, you could just walk down the road to Ingleton.
If the walk was done in reverse you could start off via one leg of the waterfalls walk which would be a nice start.
Anquet makes the route about 27.4 - 29 miles depending on the exact route taken.
I have not done this walk in full yet, though have done all the route at one time or another.
I had hoped to do it this year but didn't get round to it.
