This is an easy walk starting from the large carpark at Butt/Duhalo (W34900 86100) and following the track (which is show as part of the Dulhallow way on the Discovery map) past bog works along the access road to Seefins mast covered summit. There are interesting views south to others of the Boggeraghs. The summit itself has telecoms towers with very scruffy ancillary equipment, and, unusually, a rotatable amateur radio aerial which is controlled remotely.

If you are worried about the no access signs then make a bee-line from the car-park along the line of a fence to the 486m spot height and on to Seefin itself. There is a track indicating that others have taken this route before.

An alternative approach, and one that gives access to the East top, is to park at A (W37314 87049) where there is room for multiple cars. Head west along track for about 200m to a crossroads of sorts, turn left and follow good track south-west then west for about 1.2km until you reach B (W36256 86328), where you'll see a rough, grassy/boggy track running NW. This eventually becomes single file, but continues all the way to the summit. There are three cairns of sorts, all of different sizes, but the high point is actually a large grassy mound 20m south of these. Allow roughly 45 minutes up and down.
