An excellent mountain that is well worth the effort to reach, Approached from Loch Bheinn a' Mheadhoin in Glen Affric and cycled to Alltbeithe which took about 1.5 hours. Climbed An Socach and then Mullach na Dheiragain before ascending Ceathreamhnan. Returned back to Alltbeithe for the cycle back which made the route about 10 hours long. Ceathreamhnan would be well worth a return just to explore its many ridges and tops. In fact the Munro Mullach na Dheiragain is really just an extension of Ceathreamhnan's east ridge.
