This mountain is best climbed by taking the second road to your left on the Dublin side of Kilbeheny where there is a signpost marked "Galtycastle".
Follow this minor road uphill ignoring the turn-off to the right (also signposted Galtycastle) and taking the right hand fork at the Y junction after it.
After travelling a further 1.2 kms on this tarred road it turns 90 degrees to the left and downhill to a farmyard.
Park on the roadside at this turn R86912 19635 A (room for 3-4 cars) and you will notice a rough track in front of you on leading past a new house and up towards the hillside.
Follow this track past the house and an abandoned mobile home and hop the fence to your left to pick up a rough forestry track also running uphill.
After following the forestry track for a short distance it turns sharply downhill.
Cross the wire fence to your right and onto open hillside to reach the summit .
The summit is marked by a small pile of stones.
Do not descend to the east or west of the summit ,it is very very steep and slippery the best route is north to the Galty main ridge where a fine circuit can be had by taking in Lyracappul and the Knockaterriffs.
As you descend to the north on to the lowest point of the col before heading up to the Galty ridge there is a turf track that leads down to the west into the Blackrock river valley.
This was used as an access point to the many turf cuttings on Monabrack during the Second World War. Trackback: https://mountainviews.ie/summit/231/comment/4991/

While the cairn is modest, the view of most of the West end of the Galtees is outstanding from here. Trackback: https://mountainviews.ie/summit/231/comment/559/

Going up the col towards Carrignabinnia looking back at Monabrack (Lyracappul SE Top).
Taken as part of a horse shoe starting at Grid Ref: R 862 208 B ,up the track to the Mobile home -then follow the track along the edge of the trees(not on map) to the the point where it swings down sharply to the left.Cross the fence and head on a 346 deg bearing to the summit of Monabrack.From there on to Carrignabinnia , across the ridge to Lyracappul than down to Knockaterriff Beg and Knockaterriff to meet a track with a well built stone wall running along by it. Follow the track to a gate by a shed near a river then right to a second gate then sharp left up a new track through some young trees to an abandoned farmhouse on the side of Carrigeen Mountain - follow the track from the farmhouse and take the right fork to return to the starting point.Good conditions generally under footwith and excellent views. 5 hrs and 12 kms.

Paddy Dillon gives another name for this mountain: Monabrack. It is joined to the main line of the Galtees by a broad ridge with extensive signs of bog-workings. According to Dillon, Monabrack comes from Móin na bhráca or speckled bog. Whatever about “speckled” the col certainly is an unusual sight at this height as shown in this picture taken from near the summit, looking north towards the main ridge.

Shown as an unnamed 629 mtr peak on the OS74 map. The picture shows the view from behind the small cairn on the summit of Monabrack looking North-West. The ridge that goes up past the old peat workings to Carrignabinnia can be clearly seen. Easiest way to get to it is from the South South East, up a gentle slope from the obvious path marked on the OS74 map. Trackback: https://mountainviews.ie/summit/231/comment/1618/

Climbed Monabrack on 10 10 10 as the fifth and final top of a circuit that also included Temple Hill, Knockaterrif Beg, Lyracappul and Carrignabinnia (For previous part of the route see my comments on Carrignabinnia). On leaving Carrignabinnia R8500023700 C we went SE across a broad flat moorland and crossed over a wall. As we started to descend a spur, heading for Monabrack, our direction changed to just east of south passing over a prominant litte knoll on the way down to the coll R8560022300 D. The climb up to the top of Monabrack was steep and long, made more so by a false top crossed some way from the summit area. Coming as it did for us as the last of a five top round it was the sting in the tail. From the flat summit area, marked by a small pile of stones R8597721887 E we had an excellent view of the full Galtymore ridge and back to Lyracappul. To complete our walk we continued SE down a long spur to pick up a fence and grassy track at around R8620021200 F and then down to a forest path, past an old abandoned mobile home, back to the start R8680019700 G The last part of our walk, from the top of Monabrack down to the start, could be reversed and used as an access route for this mountain.
