The easiest place to start this is from the Glanbeg Lough carpark at V70197 53853 A. Go east from here on boggy rough ground up the long nose that leads to the summit. Walking time to top is around 1h15. Descent could be the same way however for variety it is also possible to drop towards the lake. The ground here is unpleasant and boggy but easier to go down than up. Linkback: https://mountainviews.ie/summit/1491/comment/18176/

Tooreennamna lies just west of the Cummeengeera circuit above Ardgroom, As it it is tricky to include in that circuit, it is probably best included as a circuit of Glenbeg Lough or climbed by itself.

Approaching from the lough, Tooreennamna presents a rocky face and an apparently obvious peak. This however, is only the first of many false summits from this direction, each one craggier than the next, which unfold as you climb. The actual summit, when finally reached is somewhat of an anti-climax, a small plateau surrounded by perhaps eight prominences, at least 5 of which are contenders for the actual peak.

The climb upwards from the lough can be as easy or as hard as you like. There are plenty of opportunities to scramble, but equally all obstacles can be avoided by picking your way up.

I descended into the valley, aiming to hit the lough about halfway along its length. This is straighforward except for the 300m width of the most aggressive elephant grass I have yet encountered, which lies between you and the lough. Linkback: https://mountainviews.ie/summit/1491/comment/18685/

This summit, at least on the approach from Glenbeg Lough, is characterised by the number of false summits that emerge as you gain height. Linkback: https://mountainviews.ie/summit/1491/comment/18687/

I visited the Arderin Beg Tooreennamna as part of an extended circuit of Cummeenageera, departed ridge from
V72630 53914 B and made my way out over fairly reasonably dry rocky ground with a few small craggy areas easily
circumnavigated to the top of Tooreennmna. The actual top was fairly evident, a round trip from the circuit took me
40 mins. Thanks to my fellow traveller Onzy for the patience. Well worth a visit from the round, pick a clear day ! Linkback: https://mountainviews.ie/summit/1491/comment/22202/
