Moruisg is one of the smaller Munros and unlike most of the Torridon Mountains it is easily accessible from the A890. Its neighbouring peak Sgurr nan Ceannaichean was demoted from the Munro tables in 2009 which is a shame as it possibly is the better hill with its craggy northern faces.
Moruisg sits to the east of a large coire called Coire Toll nan Bian. The summit is infact right on the eastern rim. This steep corrie is well seen from the main road and is probably Moruisg's best feature. The slopes to the north are grassy and easy. The southern slopes drop steeply to Gleann Fhiodhaig but are not often used. The north east slopes are craggy due to the presence of several other small corries. A ridge runs SW skirting round the rim of Coire Toll nan Bian to connecting peak Sgurr nan Ceannaichean. This is worth a visit as the traverse round the corrie is a superb walk and you never know when it will be promoted to being a Munro again. Most ascents use Moruisg's easy northern slopes.
The most logical starting place is from the A890 just south of Loch Sgamhain where there is parking available. Moruisg does not get the best press in comparison to its more well known neighbours but despite its height possesses a lot of nice little features and if combined with Sgurr nan Ceannaichean makes a fine day out.
