Darwen Tower

I've rode to Darwen Tower twice, the first time was with Ali and the way there was great but the way back we got a little lost and it wasn't rideable. Then I went with Carolyn and it was all rideable but we went out and back from Rivington the same way. So today I am going to plan a long route that takes in Darwen Tower and then try and ride it next week. Adding Darwen Tower into the Pike and Peel Tower will make a nice long route. So really what I need to work out is how to get over to Peel Tower from Darwen Tower. Then go and explore and find out if it is rideable.
