Park at R92356 57035 A, room for 3 cars. This is a forest and wind farm access track although it could be mistaken for a farm road as there are no trees visible at first. There is a pedestrian access swing gate to the left. Continue SWW along track for about 2km to roughly R91259 56239 B, where there is a windmill and the track broadens. Climb the bank behind the windmill and head SW for about 300m across very rough ground - old clear fell, heather, reeds, uneven ground - the high point which is unmarked.

Poor old Tooreen.You'd search long and hard to find a reason to visit its summit which consists of a mast in a rough clearing. The locality however is a little more interesting. Underneath its east face in the townland of Reafadda is an abandoned copper mine.Hollyford mine was in operation periodically between 1837 and 1862. The Mining Company of Ireland controlled operations from 1837 to 1839 but owing to problems with water mining was suspended and the lease was eventually cancelled in 1840. The mine was reopened under private hands and was worked more or less continuously from the mid 1840s until 1862 when low copper prices forced closure.
The host rock in the mine was described by Wynne (1860) as “hard grits and hard splintery shales”. Three mineralized lodes or veins occur in the area and all were mined to some degree. Two veins trend northnorthwest and are linked by a cross vein trending roughly east-west. The Ballycohen vein in the east was apparently the earliest worked; the Hollyford vein in the west was the one on which most mining was carried out in the mid-19th century. Workings on this vein reached 90 fathoms (165m). The Hollyford vein is described as a near-vertical vein ranging from 0.15 to almost 2m in width.
Several original mine features still remain on the site Of the two chimneys, one remains standing but is showing signs of instability. Only the base of the other chimney survives, covered in moss and surrounded by trees and shrubs. There is no obvious trace of most of the eight shafts that are marked on old maps. However, the main shaft, close to the chimney, is still visible but blocked at a depth of 2m below the surface. Local people have indicated that most shafts are merely covered over and not properly sealed. The mine manager’s house and adjacent mine buildings have been restored as a dwelling. The field in which the chimney stands is used as pasture for cattle.
The possibility of reopening the mine was raised in the Dail in 1956 however the Minister at the time stated he would only support its reopening as a private business venture. Linkback: https://mountainviews.ie/summit/597/comment/6645/

Not unusual for the Shannon Area a summit located in the middle of a wind farm but it sure makes access easy especially in this case as a marked trail runs thru it. Parking at the entrance R9026654933 C head for wind turbine T15 and just before same enter field thru farm gate heading for point R9104955949 D this will allow you an easy stroll to the summit without the problems associated with walking over felled forestry or thru planted trees.

As mentioned in the short summary the first 2km SSW along the track is a pleasant stroll. Then it took me roughly the same time to traverse the final 300m to the summit. The last section from R91259 56239 B is across extremely rough ground consisting of very old clear fell, scutch grass, heather and reeds, all on uneven ground - I fell twice in 300m and was also prodded numerous times by old branches. One happy circumstance is that the ground was frozen, otherwise I'd imagine this would be even worse. The cold, wintry weather also brightened some of the landscape considerably.

I had Tooreen still to bag to complete the cluster of hills in Co. Tipperary.

Felling has now been completed and a contractor is ‘landscaping’ the former forest area. The stony tracks look too good for just forestry so they are probably destined for wind farm access. No doubt the anemometer near the top will have measured all there is to measure and Tooreen will undergo the same as neighbouring Knockastanna i.e. plunk a couple of turbines on its slope, padlock the gate it and plaster ‘No Trespassing’ signs all over.

I started from the forestry entrance at Barna (pointed out by jackill) then pushed up in a SW direction partly over an adjacent field partly over an old access road on the edge of the former forest, passing through an area called Cummer Beg on some maps, proceeded as best as possible to the top avoiding debris from the felling activities.

It took about 1 hour to reach the top of this otherwise unexciting hill.

At Barna there is a sign about a temporary diversion of the Multeen Way which presumably ran over Tooreen (I did not investigate further). Linkback: https://mountainviews.ie/summit/597/comment/6757/
