The purpose of this walk is to reach the Maumtrasna plateau and Maumtrasna NE top (MNET). The lattter is quite possibly an Arderin Beg, however to confirm this will need survey quality measurement.
It also goes near Buckaun East Top. This summit doesn't quite make the criterion for an Arderin Beg, being around 5m short. Nevertheless it enjoys a very significant position. Incorporating it makes walking around Maumtrasna more interesting.
The route taken here does not go up the eastern nose of MNET.Other shared tracks do take this steep route, however it is relatively straightforward to circle round the ridge and come at the top from the NE. This route is a little longer but is definitely safer and gives great views into the valley between Maumtrasna and Barnahowna.
Maumtrasna NE Top is an extremely minor bump, though nobody should be in any doubt that there are extreme slopes to its north and south particularly.
It makes for some great views over Dirkbeg Lough.

Walking around the head of the valley that Dirkbeg Lough is in, you will find extremely rough ground without any sign of a path.
Returning, this route comes down off the south side of Buckaun, partly because the end of the ridge or at least its northern side is cliffy.

All in all this route exploits the sides of Maumtrasna, way better than the flat top.
