[RWD version 1 ] This route follows the obvious windfarm access road as suggested by others up Cronalaght from the SW. Cronalaght is almost an independent summit on its own; it has a telecoms tower near the top at around 395m Continue on from there across rough untracked ground to Tievelahid. On the occasion we were there, we had to shelter from wind driven hail.
Head from there to Carntreena via the broad ridge. In an effort to avoid the driving rain/hail we veered left, that is north, but found the ground was covered in gullies in the peat crossing our path so we returned to the middle of the ridge to get to Carntreena.
Mindful of the weather we decided to contour at around 300 to 350m to get back to the windfarm rather than go back along the higher ridges. This probably was beneficial but was certainly tiring because of rough ground with gullies in the peat.
Eventually we could see the waving arms of the windmills, a very welcome sight.
