Cruach Eoghanach is a handy outing on the days when you get out of the car, feel the force of the wind and rain, look at the main Bluestacks on the other side of the road and think 'sod this for a game of soldiers'.
Indy and myself parked up near the quarry on the road branching off the N15 (see madfrankie's notes on this summit) and followed the track south. I was using the 3rd edition of OSI sheet 11, a map whose approximations and embellishments hereabouts were already well known to me. Suffice to say the route up the mountain isn't quite as represented on it...just follow the track south past a couple of turns (see the track for where my attempts to interpret the map were undone by reality) before turning properly uphill at an obvious junction. From here it's steady going to the top, with a short dip being crossed before the final short climb.
If one can disregard the radio gubbins up there it's an impressively wild area, but Indy had been promised there was ham back in the car so we didn't linger.
