We often see sheep walking up and down the track, and it reminded us of the old Roger Hargreaves book, "Mr. Forgetful", who had great difficulty remembering how to tell Farmer Fields that there was "a sheep loose in the lane". The railway sheep seem to live permanently along the track, moving up and down the line to find the best dinner. Sometimes the train has to slow down to let them get out of the way.
Leave the car park via the wooden archway and continue up the good forest track on the purple (Bedwen/Beech) route to reach the cache location.
Watch out for muggles on this increasingly popular path; and cyclists and horseriders too.
