There is a track from Gap Road all the way to the top of Glennagalliagh Mountain, you could even ride a mountain bike to the top without too much difficulty. Unfortunately the number of flies swarming around today did not make it an enjoyable walk up, likely a lot better to walk this one during the winter when the flies are hibernating. The top is quite unimpressive, just a gate and a sign with some barb wire fencing that has fallen down in places. The view was good though, although the cloud level was quite low, could even make out the Shannon in the distance. There were also a couple of nice vistas that opened up briefly on the way to the top as well.

The flies were just as annoying on the way back down.
