Short Summary created by Harry Goodman  16 Nov 2011
At G805 525 A take the well defined lane going E and follow it up for 1k where it peters out. A little further along note some ruined farm buildings and just beyond these a stream. Follow the stream uphill as it forms an obvious and deep gully. Continue up the high left bank to the gully's end and then go along a fence running uphill to a fence junction at G8243651919 B. Pick up a small but obvious gully in the hillside and follow it up to, and then through, an eroded area of peat hags G8278051878 C some 2.5 k into the walk. Continue up a few metres to gain the crest and then go ENE along the broad flat top to the trig pillar and a substantial cairn G8330452069 D. The distance up and back is just over 6k. There are fine views NE over L. Melvin and N to the Bluestacks. To the W is Truskmore, the highest of the Dartry Mountains, and further around S the Castegal ridge.

A long ridge extends South East from the highest point on Arroo to Lough Aganny. This picture was taken from near Lough Aganny, looking towards the cliffs of Largy, part of a broad spur that leads to the right of the picture to Truskmore. Largy itself is not so interesting apart from its cliffs, however centrally on the skyline can be seen Crockauns (463m) and to the left edge the start of the rise to Hangmans Hill and Keelogyboy Mountain (438m). As written up by Claude Wall, these are part of the Castlegal Mountains. "The Castlegal Mountains, south of Glencar, are somewhat neglected owing to the proximity of the Dartry range, but they provide a good ridge walk ... "
The Lough that is visible is Glenade Lough. This view will be familar to anyone who has done the "Benbulben Challenge" as the route from Arroo goes near Lough Aganny, passes to the right of Glenade Lough, turns left diagonally upwards towards the end of the cliffs and then right again along the top of the cliffs.

Arroo from the east
by Colin Murphy  11 Feb 2013
Most walkers approach Arroo from the steeply-sided west slope, but as I wanted to also take in Conwal North top to the east, I decided to start from the eastern slopes. There is a parking space opposite a track, just where some forestry starts at G858 516 E. (Alternately there is another clear parking space 300m or so south up the road). Follow the distinct track across the road from the parking spot, which continues for about 500m, and then peters out amid a turf-cutting area. Continue directly west across gently rising and in parts, distinctly boggy land (although it is relatively easy to navigate around the very marshy bits). Around G848 516 F the grassy ground starts to rise fairly steeply, but is very firm underfoot. The slope eases about 300m later and there is a relatively gentle climb all the way to the summit, the approach offering a partial view of the towering cliffs on Arroo's north side. There is also a fascinating area to the north-east below the summit, (see pic) featuring a number of diminutive but very sharp peaks, surrounded by grassy bumps and knolls, which looks like the kind of place you might find a hobbit living! Returned the way I'd come, getting back to the car precisely 2 hours later. Linkback:

Started this walk at a track in the townland of Aghanlish 80481 52522 G (95m). Parking is a problem as the road is very narrow. I went to the bungalow on the other side of the hedge to seek permission to park. However, there was no one home. A woman in the neighbouring house was quick to spot me and to investigate what I was doing there. When I explained that I was looking for permission to park she directed me to the first house on the left about 500m further down the road, which belonged to a family member of the people who owned the bungalow. The gentleman at the house was very obliging and allowed me to park in the drive of the bungalow. I pulled in well to the side so as not to cause any obstruction. The track runs from the road for about 500m before reaching a gate at the side of an outbuilding and then continues for about another 100 metres or so before it peters out naturally into the lower end of a Burn. From here I took a bearing of 116 degrees SW. I kept to the left bank of the Burn until I was able to cross above it to a fence 82290 51925 H (347m). Once over the fence I continued on the same bearing veering to the right of the main bulk of the mountain so as to reach the lower end of an obvious ridge. At the top of the ridge I turned left towards the mountain climbing a narrow spine, the top of which 82755 51852 I (495m), adjoins an eroded area of peat and shingle just below the top of the plateau. I took a bearing of 56 degrees NE from here, which is about 500m from the summit cairn. However, if you veer left to the end the eroded area there is a fairly well worn track which swings across to the other side of the plateau and from there all the way to the summit marked by a Trig point & cairn. GPS reading here was 83303 52060 J with a height of 522m. The views from the summit are spectacular. To the west Tievebaun & Truskmore looked resplendent as they basked in the sunshine. Across Donegal Bay Slieve League was clearly visible. Below and to the east the impressive Lough Melvin and beyond that to the north-east Lough Erne. Due south the hills of County Leitrim were bathed in wonderful sunshine. The walk (I returned by same route) took 2 and a half hours and was one of the most pleasant I have enjoyed in recent times. On way back to car I noticed some fresh blood on the track and shortly after a sheep with an obvious limp and in some distress. On arriving at the car the gentleman who owned the bungalow was home and I informed him about the animal. He in turn informed his brother-in-law who owned the sheep. Linkback:

This picture shows the steep cliffs to the North and East of the summit of Arroo. According to Duchas, the Irish Heritage service, the steep cliffs and rocks beneath them contain many botanical rarities, including various forms of Saxifrage, Mountain Avens and Mountain Sorrel. Linkback:

An unexpected treat
by Harry Goodman  17 Nov 2011
Climbed Arroo Mt as part of a circuit which also included Aganny Top, Agalateeve and Keeloges. Having parked off road about 100m south we took a well defined lane up from Aganlish G8048152522 G. The area we parked at was along the boundary wall of a house but as no one was at home I asked a farmer tending sheep nearby if he thought I could park there and he said he did not see it as a problem as the car was off road and not obstructing access. The track up was good and finally petered out about 1k up. A little further along we came to some ruined farm buildings and just beyond these a stream. As we followed the stream uphill it formed an obvious and deep gulley which we then continued along on the high left hand bank to its end and then along a fence running uphill to a fence junction at G8243651919 B. We then continued up along another small but obvious gulley in the hillside to and up through an eroded area of peat hags to G8278051878 C some 2.5 k into the walk and just below the crest of the summit ridge. On reaching the crest we walked E along its broad flat top to the Trig Pillar and a substantial cairn G8330452069 D. For the purist the ground seems to be a little higher some 40/50 metres just SW of the cairn at G8328352047 K. Distance from start 3.17k.Views out over Lough Melvin to NE and the Bluestacks to the N were superb as were those W over Truskmore and S to the Castegal ridge. Rather than retrace our steps we then headed for S for Aganny Top. Linkback:
