Assuming that civilisation ends at Glasgow, these directions will begin at that point.

Take the M8 through and round Glasgow at which point there are two potential routes to Ardmarnoch

Route One

Continue along the M8 through Greenock and continuing on to Gourock.

Go through Gourock to a ferry jetty for "Western Ferries" (ignore the jetty for Caledonian MacBrayne Ferries).

Take the ferry to Dunoon. The ferries go every 30 minutes and take about 10 minutes.

Coming off the ferry turn immediately right and go along the coast for 3 or 4 miles until reaching Sandbank. At Sandbank a T-junction is met and take the right turning towards Strachur and go along this road for approximately 2 miles. Turn left at a sign for Tighnabruaich and Colintraive. Go along this road which winds through fairly desolate country for about 12 miles until you come to another T-junction. Here turn right which will again be signposted for Strachur and go along for 1 mile until a left turning to Tighnabruaich.

Follow this road which is spectacular and rise and turns and then falls again into the village of Tighnabruaich after about 6 or 7 miles. You will come to a T-junction right on the sea-shore, turn right signposted for Kames and follow that road round taking a sharp right bend at a police station and going over a hill into a small village called millhouse. Here take another sharp corner to the right but still follow the road which is the B8000.

From Millhouse go along about 4 or 5 miles until you see a sign to the left pointing to Ardmarnoch and saying 1/2 mile.

In fact it is 2 miles, after 1/2 mile you come to the estate gate and 1 1/2 miles further on to the Gate Lodge.

Route Two

Leave the M8 at a sign for Erskine Bridge. Going over the bridge (all bridges in Scotland are now toll free) and immediately exit to the left for Crianlarich and Campbeltown. Follow this road through the edge of Dumbarton, always following signs for Crianlarich and Campbeltown, the road is a dual carraigeway then single carraigeway and eventually runs along the side of Loch Lomond.

After about 25 miles from Erskine Bridge you will come to a small village called Tarbet. Take the left fork in Tarbet again signposted for Campbeltown and go through Arrochar which is at the head of Loch Long. Go round the head of the loch continuing on the same road and eventually leaving the glen to rise 1,000 feet up, still on the same road to something called the Rest and Be Thankful Pass, although it is not actually signposted!

Go over the top of the pass continuing on the same road, come down into the next glen, turn sharply to the left and after about 2 or 3 miles from the top of the glen you will see a brown roadsign for the Cowal Peninsula indicating Dunoon and Bute Ferries to the left.

Take this road and carry on through St Catherines into Strachur which is about 10 miles. In Strachur take a right turning signposted for Tighnabruaich.

After about 4 miles you will come to a signpost which says Tighnabruaich in both directions, going right through Kilfinan there is a very pretty winding lochside B road which after 20 miles comes to the Ardmarnoch sign.

Carrying on, on the main road leads down to Tighnabruaich at the same place as taking the other route.

The ferry route is only about 50 miles driving but takes about 1 3/4 hours - 2 hours, the road only route is about 80 miles but takes 1 1/2 hours - 1 3/4 hours.
