Spent part of summers up there.
We just called it the Glen also.
Officially?.Castlereagh Glen or Cregagh Glen.
Use too be an old Church at entrance..
It’s right beside Mc Caughan Park..on The Knockbreda Dual Carriageway .
Recall The Swing over The Ravine..seemed massive at the time.
Robbie Burns was the daredevil,he would climb tree,creep onto branch and tie the rope.
Waterfall was a just up stream.
