Just to the east of Barns Ness lighthouse is the wreck of wooden barge.
From here you have a view of Torness Nuclear Power Station and on the Horizon to the east you can see St Abb's Head.
If you come at night you'll be able to see the Light of the St Abb's Head Lighthouse, Bass Rock and May Island. But sadly not the light at Barns Ness as this lighthouse has now been decomissioned.
The cache container is an ammo box.
