Ben Lui is the highest and most famous of a group of four Munros that lie south of Glen_Lochy Glen Lochy and about 10 km north of the top end of Loch Lomond. The other three peaks in the group are Beinn a' Chleibh Ben Oss and Beinn Dubhchraig.
You might get an excellent sight at the eastern face of Beinn Laoigh if you stand on the Fillan Bridge, which is located on the road that leads from Crianlarich to Tyndrum. Not far from the old Dailrigh schoolhouse, which is currently being used as a barn, is the point where the Cononish track first branches off into its own direction. On the Allt a Rund, a sheep fank can be reached after a short hike. From the point where the burn's two primary branches converge, known as the burn's mouth, there are two distinct routes that lead into Coire Gaothaich, from where you can choose whichever one you want. On each side of the ridge that climbs to the summit, there is a short spur that can be taken to reach a rocky crest that culminates in a rounded peak. On the left-hand side of the image is a gigantic cairn that is a complete mess, and it serves as a marker for the highest point. In the winter, climbing Central Gully, the steep couloir that dominates the hanging coire, is considered to be one of the most traditional and popular climbing routes for experienced mountaineers.
When leaving Glen Lochy, shorter paths often require the traveller to make their way through clearings in the forest. Start your journey from a parking lot that is located close to the railroad bridge that spans the mouth of the Eas Daimh. There are footbridges leading to the east and west, but this location is quite near to where it joins the River Lochy, which may be crossed on foot. A forested region to the east of the historic Glenlochy Crossing signal box was frequently used as the starting point for ascents (Grid Reference NN 255295). A more recent structure can be seen to the west, although when viewed from the road, it is almost completely obstructed by a small hill. Just to the north of the highway that is currently in use, there is a sliver of the old road that has been preserved, and this can be an extremely useful point of reference. One may spot a shack on the other side of the railroad from the spot where a muddy path winds through the heathland.
Following the railroad from either of the bridges will lead you to the stile that is located close to the east of the Eas Daimh Bridge. A trail may be found just below the Eas Morag waterfall that leads up and over a footbridge while remaining on the left (or north) bank of the burn. Keep to the north side of the burn and cross when the largest tributary joins the main stream; alternatively, go to the stile in the fence at the base of Ciochan Beinn Laoigh. Following the course of the creek for a time, the path then begins its steep ascent through a firebreak and continues until it reaches the open grassland of Fionn Choirein. When the water level is high enough, cross the Eas Daimh using the footbridge across the Eas Morag, and then go downstream to the tributary's plank bridge, which is located on the western bank. You might come across a stretch of steep scree to the left of the shattered face of Beinn a' Chlèibh, high above the forest fence (stile), which offers a practical exit path from the headwall of the coire. Grassy tiers lead up to a col, and from there it is only a brief ascent south-west around the rim of the coire to the cairns that mark the summit of Beinn a' Chlèibh. A more difficult ascent to the north-east leads to Beinn Laoigh, which can be reached by climbing the mountain.
The Eas Daimh is a more appealing option for getting to Beinn Laoigh than the other routes (stile in an angled section of the fence close to the burn). Views of the craggy bluffs of Ciochan Beinn Laoigh can be had by looking to the right, above the tree line. The northern summit, which is located above Coire Gaothaich, is denoted by a cairn and features a steep ascent from a grassy nose to a ridge crest that gradually narrows as it approaches the actual peak. The rim of this gigantic scoop offers a reasonably straightforward and expedient route up to the southern peak.
