We spent a couple of days in Glencolmcille, doing two walks, one with the family part of the way on the Tower Loop, up to the lookout Tower, then on to Sturrall Head. On the second day I went on my own up to Croaghacullion, starting out at the Church of Ireland church, and initially taking the waymarked loop walk route counterclockwise. The track can be followed to the prominent communications mast, where I headed off to the right/east across open bog. It was then just a question of ascending increasingly high little summits until the top was reached. The ground was very dry in the conditions I had, but it looked like this route could be a real quagmire after a wet period. After initial heather covered ground, and a good view stretches of peat hags, the terrain became increasingly eroded, exposing large areas of bare peat, and stony areas where the bedrock came to the surface. Views were great all the way up, out to sea past Glencolmcille, down to Port, over to Slieve League and beyond to the Dartry Mountains. There were also several picturesque loughs near the summit. If I was only there for one day however, I would try to combine this summit with a longer walk that stretches over to the lookout tower and Sturrall Head on the coast. Sturrall Head in particular was spectacular, and probably better than any view from Croaghacullion itself. Linkback: https://mountainviews.ie/summit/873/comment/18122/
