The cache is not at the given co-ordinates.
An apt name for a cache given its location close to Durham University Observatory. The walk up the hill from Potters Bank offers arguably the best view of the Cathedral from anywhere in the city. It is also a popular spot for picnics during the spring and summer months when the hill is carpeted in wild flowers. If you enjoy the view please take a photo and add it to your log - we would love to see all your pictures!
Recommended parking is either on Potters Bank in the parking spaces towards the bottom of the bank or in Elvet Hill Road opposite the graveyard (parking charges apply at both locations).
Cache is located at N54 46.ABC, W001 35.DEF
