A sketchy path follows the west bank of the stream up to Glas Lough, after which it cuts up right through the heather - it is just visible in this picture. There is very little opportunity to go wrong in the ascent, but to find the top of this path in descent, you need to turn sharp right as soon as the ridge levels out. If you miss the path, the safest option would be to continue down the ridge until easier ground appears on the right. Linkback: https://mountainviews.ie/summit/27/comment/1898/
