[RWD version 1 ] This walk starts from the good parking at a disused national school and starts on the Bluestacks Way. Near the early bridge we encountered a gate with a no access sign. This was puzzling because there were Bluestacks Way marker poles before and after the gate. We decided to press on. Later on members of our party came back this way and encountered the farmer, who did not seem concerned.
However it would be possible to bypass this no access completely by starting at Gaugin Mountain starting point as used in track/2209/

As you rise there is a series of false summits before you reach Glascarns Hill at 578m. There were two possible highest points for Glascarns so we surveyed both and found that the most northerly was 248mm higher than the more southerly. The height we got therefore is 578.3m with prominence 28.7m. The latter was much higher than the previous estimated of 20m, but not quite enough to make Glascarns an Arderin. Pressing on to Croaghbane in good weather with little wind, no rain and some wintry sun we could see into the valley of the Owendoo river. Croaghbane we measured at 640.9m, changing nothing in its status. From Croaghbane we went SE along the ridge. Be careful not to go west along the wrong ridge unless you want to go to Ardnageer. There is a big notch in the ridge towards Croaghbarnes then. Wend your way through various loughs to reach Croaghbarnes. Measurement showed this to be 498.8m so confirming that it is not an Arderin. We continued on to the Corrabbler river valley. It as easy enough to get down, but the going was slow on wet trackless terrain beside the river. We mostly stayed to the right bank looking down the stream.

Ford
When we reached the outflow of Lough Belshade we found it to be very substantial and we needed to ford it, getting our feet properly wet.
There was then a longish, wetly dismal walk down to where we had a car parked near Edergole.

Nevertheless, overall a great day of good views, light wind and mostly good going.
