This is a fairly short walk though we took our time about it. As with other places that are rarely visited it lacks many paths and has long vegetation that covers unpredicatable terrain that we ran into at times.
We looked at the information from IainT about the summit, who described the place as " a maze of rock slabs, gorse and tussocks, an extremely rough place" and started from the SW of the top. We gained additional advice from some people nearby who indicated a way through what appeared to be a very mature stand of sitka spruce which brought us somewhat more easily higher. However even those widely spaced and large trees had a surprise for us later since further up the slope many of them had blown over creating an astonishing tangle to move through.

The terrain on many lower hills around here is notorious. Look at the information for example for Derreenavurrig described by an experienced member as "Impossible to make progress due to rock bench followed by gulley and/or swamp followed by rock bench, and so on and on." The route we took up Knockanamadane was relatively easy and we reached the high spectacular ridge which has a fence along its length including over the top.

The summit is over 4km from any other summits and provides a gorgeous platform for viewing the Dunkerrons and Kenmare bay. The whole Dunkerron ridge bends northwards putting places like Knockanamadane loosely into the middle of an arc. The day we were there was somewhat misty however.

On the way down we (ok, I) decided to vary the route to go more south than south-west. I really do not recommend this. You find yourself going against the grain of the land, on uncertain tussock covered terrain. We changed route to go towards the forestry we had originally used and it was there we discovered the blown over trees.

There may well be other places to visit Knockanamadane from, for example from the north, but if you are coming from the SW stick to the route we took to ascend.
Your reward for visiting the summit is a superb view.
