Download what3words to your PC and device, watch https://www.youtube.com/watch?v=yJPjocn86s0 and import my CSV file, this will add 4 items to your ‘my lists’, Sign on locations, Flag post, Incident Huts and possible parking locations (the parking might need a few updates).
NOTE; if you use navigate in what3words to get to post it may not give good routes, the link road may be closed.
Once you have the file installed you should get close to where you need to be then you can edit the location on your device to suit you better.
I will update the file from time to time as I find better locations.
