Another cache on the Berwickshire Castal Path between Eyemouth and Coldingham.
Hallydown Shore is a secluded rocky bay about halfway between Eyemouth and Coldingham with a wealth of interesting geology, including a fine sea stack. Do not attempt to follow your GPSr arrow from the coastal path as this will take you over the cliff edge! A waypoint is given for the start of a track that leads down to the shore from the coastal path.
It is not recommended to attempt this cache at high tide or in the dark!
