(S/E) Exit Ben A'an car park at the main entrance and directly across the road you will see the footpath for Ben A’an heading in a north-east direction.
After an initial steep ascent lasting half a kilometer, the path levels out.
(1) At 265m elevation there is a crossroads - continue ahead (North West) to go across the hillside.
At 290m elevation there is another steep ascent involving a scramble.
(2) The path then circles round to reach the summit of Ben A'an.
(3) Descending via the same initial footpath, after 100m and before you reach the scramble, look out for a lesser-used grassy track on your left. Follow this downhill (North West) towards the forest, enjoying the views of Loch Katrine as you go.
(4) You will reach a stile over a high deer fence. Do not cross. Instead, turn left (West) and walk down the fence-line, keeping the fence on your right-hand side.
(5) After a distance of 900m and an elevation drop of 220m, you will emerge out onto a minor road on the banks of Loch Katrine. Turn left (South) to walk along the road.
(6) After 1.3km you will reach the car park at Trossaschs Pier. Walk through the car park - the road becomes A821/Dukes Pass.
You can either keep to the road all the way to Ben A’an Car Park (1.6km) or you can take a slightly more scenic and longer route (2km).
More scenic/longer route:
Walk along A821/ Dukes Pass for 500m, turning right (South West) onto a minor road known as the Pass of Achray.
(7) Almost immediately turn left (South East) onto a footpath. Follow this mix of earth path and boardwalk for 800m to reach a small car park (300m along there is a fork - you can go either way).
Leave the car park from the main entrance and turn left (NorthEast) onto A821/Dukes Pass, then right (East) at the end of the road. Ben A’an Car Park is 300m along on your right-hand side (S/E)
