The cache container is a bison tube.
It is hidden quite well.
There often are muggles all around this place. If so, please come back later. Most often you can search this area without worrying about muggles.
Sometimes there is an entrance fee for entering with a vehicle. There is never an entrance fee for entering on foot or on a bicycle.
Good luck ! ! !
