Moel fferna is a free hand and quite awkward to rig around the tree. Getting back up can be quite difficult too due to the awkwardness of the tree position. Last time we went, we set up a two ropes pulley system, pulled the least capable up first from the bottom then last most able man pulls himself up.
Plenty along the A5 to look at, moel fferna is a bit of a buggar to drive within a nice walking range, we tend to park around the back on the gravel road, rather than off the A5.
