This is A.Hendroffs route from the excellent Dingle, Iveragh and Beara Peninsulas. The start is nice and easy and the views are excellent throughout. The walking surface is rarely easy, so it's a tough 20km, the descent to from the SE of Coomnadiha to Commnalack is tricky in the dry, I can only imagine what it would be like in the wet with inclement weather. The section from Knocknagorraveela to Cummer Top is a nice break, be sure and have a look at Cummer lake (cross the fence) which looks stunning with the Reeks in the background. Ironically, the wettest part of the walk was the section of the Beara way under Feorus, it was a bog in August. A nice walk along road which follows the shore of Lough Inchiquin soothes you back to the car.
You could easily add Cummer & Feorus East to this walk, making for a 8 summit walk, not bad for the summiteers.
