Coumaraglin is easily reached from the starting point on the road to the south. Parking at a wide Coillte entrance, it is a climb of 300m over bog to the summit. There is a large coum a couple of hundred meters to the east of the summit which is well worth viewing. I then followed the edge of the coum south for a while to enjoy the views before veering away southwest to head down to my car. Be careful if going near the coum edges. There is a horrible metal structure to support masts at the summit, and another curious large transmitter device low to the ground near the coum edge. If you can ignore these you will enjoy the walk!
