I parked at the trailhead for the newish Lettershanbally Loop and followed that loop for the first 3.5 km. Mostly standard forest track walking but the last 1 km is a nice boardwalk through flat bog, surrounded by the Maamturks and Twelve Bens. At the end of the boardwalk, the Loop meets the Western Way. Instead of following the Loop south along the Way, I headed north on the Way for 500m then crossed the fence onto the hillside at a suitable point heading for some stone ruins under some bare (at least in early March) trees. Lazy beds were also visible on the hillside above the ruins. A fresh vehicle track was visible among the ruins, so out of curiosity I followed it down to a gate, which I would pass through on the descent. Then I returned to the seanbhaile, took a few photos and headed directly up the steep, mostly grassy hilside. It was a short climb to pt. 324. The grassy hilltop has no cairn or other marker but has great views in all directions.
I headed down, taking a more northerly line as the descent was gentler in that direction. I passed close to the remains of a prehistoric fort on the lower slopes, but I didn´t cross the fence to visit it. I descended to the gate I had seen earlier. There was a lock on the gate but it was open. I followed the Western Way back to the intersection with the Lettershanbally Loop and headed back over the boardwalk. I reversed my steps rather than completing the Loop because the rest of the Loop after the boardwalk is on forestry tracks with trees blocking the view of the surroundings so it is not particularly rewarding.
I don´t know the name of this hill. I´m guessing Lettershanbally Hill. It doesn´t fit the height/prominence criteria to go in any MV list but both from the ground and from the top it feels and looks like a fairly independent summit. It has a prominence of 90m and height 324m. The slopes drop steeply away to north, west and east, and even to the southeast where the ridge leads to its parent peak, Maamturkmore/Binn Bhán, the ground drops away for over a kilometre before beginning to rise. Maamturkmore is almost 3 km away as the crow flies, so it doesn´t feel like it dominates this hill at all. The views from the summit are very good on a day as fine as the one I was up there. Views include the grassy bulk of Leenane Hill to the North, Twelve Bens, Lough Inagh, Kylemore Lough, the Benchoonas, Killary Harbour, Mweelrea, the Sheeffreys, Ben Gorm and the Atlantic Oceanin the distance. It is also accessible from Glencraff to the north, where there is parking for the Tullyconor Loop, a loop which is very short but provides an entry point for taking on this hill, or even a full Glencraff horseshoe encompassing Leenane Hill on the other side of the valley.
I didn't start recording the track until about 800m in. So actual walk length would be about 12km rather than 11.2km as recorded.
