This is one of 15 simple geocaches in a circular route set out to coincide with my 'Yorkypudding's 15th Birthday' event (GC8H3TY) which takes place on Saturday 15th February 2020, fifteen years after Yorkypudding's first geocache find, and forms part of a walk of approximately 3.6km on mostly steady terrain that should help attendees build up an appetite (and/or a thirst) on the day and won't be too challenging for others walking the circuit at a later date.
From WP15:04, continue down the A631 under the bridge, and then cross the road at the refuge on the bridge over the River Rother. Take a slight left and then walk through the rather messy open area and take the path on the right of the large blue gates. You are walking on a path with a metal fence on your left, and a treed slope on your right down to the Rother.
Update 2020-05-15: You are now looking for a black micro/small cache (about the size of two 35mm film pots end-to-end. Be careful on the slope.
