Knocklaur is roughly the midpoint on the ridge connecting Maumtrasna and Devilsmother. This explains its name, Knocklaur, meaning ‘middle hill’. There is a steady bog sweeping up to the summit from the south, while to the north of the summit ridge the ground plummets away in sharp cliffs and extremely steep slopes. The views from Knocklaur are fantastic, especially across to the ridge containing Devilsmother and Devilsmother North Top to the west, and the vast bulk of Maumtrasna to the east. Knocklaur has a large spur that juts out north into the Glennacally valley, although the severity of the gradient on this spur would prevent access to Knocklaur this way for all but the most experienced summiteers.

It can be approached from the Devilsmother ridge by joining the Knocklaur ridge at L920 630 A. An easier alternative is to park at L936 611 B which is the end of a minor road at a little hamlet. A climb of 460 metres over 2 km can be made over a mixture of bog and grassland, with several fences and a few streams to negotiate. The trudge over bog gives way to the dramatic drops into the Glennacally Valley below as you reach the summit. Caution is required at the summit or on the ridge due to dangerous drops to the north.

Knocklaur is roughly the midpoint on the ridge connecting Maumtrasna and Devilsmother. This explains its name, Knocklaur, meaning ‘middle hill’. The ridge itself has extremely steep drops along its northern side, while the southern side of the ridge is gentler. It is easy to keep well away from the steep northern drops as the ridge is quite broad. While Knocklaur can be climbed directly from the south, it is more likely to be climbed either from the Devilsmother ridge or from Maumtrasna. The views from Knocklaur are fantastic, especially across to the ridge containing Devilsmother and Devilsmother North Top to the west, and the vast bulk of Maumtrasna to the east. Knocklaur has a large spur that juts out into the Glennacally valley, although the severity of the gradient on this spur would prevent access to Knocklaur this way for all but the most experienced summiteers.

Those on a long walk can start from L935 655 C, where there is room to park a couple of cars beside a bridge. A local sheep farmer said access to the valley from here is permitted. From here cross the river and follow a fence into the valley for several hundred metres before heading directly up the steep wet slopes to gain the Devilsmother ridge. The ridge is wide and heathery, and can be followed to L920 630 A where it connects to the ridge to Knocklaur and Maumtrasna. The final haul up to Knocklaur is quite steep, although a handy fence can provide support. If including the two Devilsmother tops first, Knocklaur can be reached in about three hours.

For a quicker ascent park at L936 611 B which is the end of a minor road at a little hamlet. Although access is allowed through the farmland here, always ask first at any of the houses. From here it is a climb of 460 metres over 2 km distance to the summit of Knocklaur directly to the north. This route crosses a mixture of bog and grassland, with several fences and a few streams to negotiate. This approach would no doubt offer the greatest surprise as the trudge over bog gives way to the dramatic drops into Glennacally below as you reach the summit.

Knocklaur is an impressive spur pushing north into the Glennacally valley, or at least it is from the valley floor. Reaching it from ridge on the Maumtrasna side it's just a pull up of 40 or 50m.

Some words of caution. As so often in Ireland the north or northeasterly side of the mountain tends to be very steep. If you are trying to get off this summit to the north do not attempt the direct route down the north spur of Knocklaur -- it's very steep particularly at around elevation 250m. There is a col 540m to the West of the summit, but don't try to descend to the north there either, it' s even steeper. Your options are to descend at about L920629 D (see Route A on simulation) or follow the west ridge and climb onto Maghairlí an Deamhain north of it.

Mindful of Wicklore’s cautions of an ascent from the north and Simon3’s almost interdiction of a descent in this direction, I approached the northern spur of Knocklaur prepared if neccessary to walk around it’s base in order to find an ascent route, a line of attack so to speak.

I parked at L935 656 E, Glennacally Bridge. This is some 8km NW of Leenaun on the N59. Going through the gate directly south of the parking area, I followed the east bank of the Glennacally river. The first sections encountered here cut right through the rock forming some dramatic channels, not what you’d expect from the map. After about 1km, the river is joined by a branch from the left, the Glenfree. This was shallow when I was there and it was easy to cross. Knocklaur’s northern spur loomed large straight ahead as I continued heading south, following fairly close to the left bank of the river. After another 1km, I crossed the river just after a ridge on the opposite bank, a section of moraine perhaps? I could see an obvious green ramp heading diagonally up the incline from the left (east) side of Knocklaur’s northern spur and up to it’s central spine. The ramp starts around L93838 63581 F and ends on the spine at L93486 63545 G. This ramp is steep but is very do-able.

About halfway up the ramp I veered left, weaving through some rocky sections and going more directly up the slope, hands required. When I reached the spine, interested to see whether I should have stayed on my original course, I descended down towards the point where the ramp would have arrived. I didn’t go all the way down, but I don’t think there was any obstacle further down, so staying on the ramp would probably be an easier route up.

Once on the spine, it’s just a matter of some fairly easy scrambling up to Knocklaur summit.

The clouds hovered around the 500m mark, so while I could see down to the cols - the western one towards Devilsmother being a particularily steep descent - Devilsmother itself, the next peak on the route, remained hidden.

Firstly, if attempting this route from Glenacally Bridge (L935 657 I) please call into the farmer across the road and ask for permission to park on the obvious waste ground beside the bridge. He has installed a No Parking Sign but he's a decent man and won't have a problem with you parking if your group is small. The route up Knocklaur from here involves a very pleasant saunter along the banks of the Glenacally river for nearly a km. There are a few impressive mini gorges and falls en route. thereafter, you need to make a decision...take on the northern spur or skirt it to the west or east. i felt in good shape so decided to head straight up the spur. it's a tough but exhilarating climb involving some minor scrambling and route finding but in clear weather it poses no threat to a fit hiker with a head for heights. I would nae recommend it in poor visibility though! Once up the steep spur it's a short walk over to the summit from where the views are spectacular!
