There is an access road at G758 868 A to the communication tower near the top of Mulmosog. From the tower its a short bog trot across open moor roughly SW to the actual top where fine views are had of the flanks of Common Mtn, Killybegs and Ballinreavy Strand. I couldn't find any defining features at the top apart from some fencing and the corner of a nearby forest as well as a small hut off on a spur. The views make this small top worthwhile.

Yes, there is an access road to the comms tower just below the summit of Mulmosog, but there is also a path marked on the map starting at (757 862 B) aiming for the same destination, and it was this route I selected. Things started promisingly, but said path soon petered out amongst some fresh peat cuttings and linking with the access road by traversing across the hillside was an annoying shlep through the expected trackless, tufty and boggy grass, with a deep ditch and uncomfortably substantial (I'm 6'3 and I found it awkward) barbed wire fence providing the access road with a final defence. The summit has some mini comms equipment of its own (and very pleasing views as noted by Mr Hillsbagger), but I'm not too proud to say I used the access road rather than my route of ascent for the return.
