One approach is starting from V 896 635 A, where there is just about parking for 2 cars. Just behind the parking spot a narrow trail starts in a NE direction and continues on and off until Castle Rock, which is a prominent rise and appears almost to be a separate top. After this you continue in a northerly direction across a flattish, occasionally boggy col, losing about 80m in height before ascending again, the last 300m or so becoming quite steep. The summit is unmarked but offers great views of Kenmare Bay and the surrounding hills. Return journey to car about 7km, taking about 2 hours.

One way of accessing this summit and the other two hills in the area (Knockeirka and Killaha) is to start from where a narrow public road reaches its highest point at around V 896 635 A. There is a small amount of parking here and access onto the open hillside in such a way that it is unlikely to cause any difficulty with landowners.

Took this in as part of a circuit including Knockeirka and Killaha Mountain. See former for details of parking and ascent of that summit. At the top of Knockeirka, turned west south west and the route to Barraduff is easily visible on a clear day. In cloud or mist simply stay near the wire and post fence that runs from one summit to the other. Warning - this is met by a number of other fences along the way, though all relatively easy to get over. Going was very straightforward, perhaps gaiters useful at wetter times as we walked it in a very dry spell and even still had to skirt the odd boggy patch. The walk itself is lengthy enough, between 2 and 3 km, but fast going, took about 35 minutes to cross from Knockeirka to Barraduff. A short pull up at the end for about 50m, but very straightforward and rewarded with fine views over Dromoughty and down the Kenmare Bay. The summit is featureless, no cairns. Lovely area though, very remote feel to it. From there we moved on to Killaha Mountain, which again was easy to pick out on a clear day, and again a fence runs between the two which might be convenient in poorer visibility.

WARNING - (i) All 3 mountains contain a lot of fences for a good reason. Lots of sheep. This really is no place for a dog. At all. And (ii) the 2 hours was really for headline purposes, it took us about 2 hours 20 mins overall from car back to car, and we walked pretty fast, so allow a bit more time...
