Lough Shannagh walk leads up hill on the ‘Banns Road’, an off road farm track. The route circles Lough Shannagh (in an anti-clockwise direction) with a high point of 587m at Carn Mountain. It also follows and crosses the Mourne Wall on places.

I recommend you to stay overnight in a tent and potentially also visit Slieve Bernagh which is close by.
