Start at the car park on the south side of the village of Strathyre. Take the Forest Enterprise signed footpath over the bridge and up to the tarred road. 100m past the village school, turn left on to the hill footpath. Climb quite steeply through tall conifers for 300m to a forestry road. Turn right and walk 50m.
At time of writing the next section of path is being re-constructed, so the existing path is still being used. Turn left and zigzag up quite steeply through the conifers, which are due for felling and thinning. The path requires a bit of care in places, especially where the views open up and sheer weight of feet have made the edges crumble. As you emerge at the edge of the new pine plantation the view is outstanding.
Loch Lubnaig lies beneath like a mirror framed on the south west by Ardnandave hill and Beinn Each on the west. Continue over the small hill burn and turn right up the hillside path. This is not as broad as the forestry track but is still very visible as it follows the burn up onto the open hill and in turn climbs very steeply onto the first rugged knoll. Most people stop here as the views are outstanding and it is most definitely the picnic spot. Strathyre village is dotted below and the River Balvaig twists up into Balquhidder glen.
Go west and descend gradually for 100m to the stile over the boundary fence. Follow the path north over boggy ground. It will then rise over another knoll and the next ascent brings you to the summit of Beinn an t-Sidhein (Ben Shian). Return by the outward route.Walk courtesy of 'Glen and Mountain Guides.
