Glenarm glen is the most southerly of the nine glens of Antrim: it extends from Glenarm village southwards for about eight miles. In parts of the glen the ground rises from around 600 feet to 1000 feet above sea level.
Farming activities consist of mostly beef and sheep with some dairy type enterprises on the lower ground with the ground giving good grazing due to its limestone base.
There is an area of special scientific interest (ASSI) situated about halfway up the glen adjacent to the river. The habitat in this area is rich in plant species and wildlife and the red squirrel has recently been observed in this area.
Greenmount Hill Farm situated a few miles south west of Glenarm glen is managing a large area of hill grazing in such a way as to encourage an increase in the numbers of the Irish hare, grouse, hen harrier and curlew.as jackdaws and starlings.
