This cache is just off the public footpath/pavement and you'll have to be super stealthy. You'll find yourself at the corner of Briery Bank and Silverdale Rd, near the Catholic Church and only a stone throw away from the playing fields, but the cache is closer to the Telephone Exchange which you can't miss on the corner.
Be aware, it's a tricky one- a maximum of stealth is required. Bring your own pen as the container most definitely doesn't fit one!
