If you are driving from Glasgow,

take
the M8 from Glasgow, drive past Glasgow Airport, at junction 30 join the M898
to cross the Erskine Bridge (now toll free). While on the bridge stay in the left
lane which will take you to join the A82 towards Crianlarich. Follow the A82 up
to Tarbet (Note the spelling) where you stay in the left lane to join the A83
towards Campbeltown. Follow the A83 through Arrochar, Inveraray, Minard and Lochgair
to Lochgilphead. If you are going to Ardrishaig or Tarbert, continue to follow
the A83. Soon after you turn left at the small roundabout you are in Ardrishaig.
You will find a signboard "Ardrishaig Welcomes You" or if the local
juveniles have been working at it, as often they do, the sign may read "Haste
Ye Back". To go to Tarbert, follow the A83. This 14 mile stretch of the road
is, to say the least, wiggly and it has 107 bends and curves. (Be prepared for
an occasional sheep, or a deer on the road at night) At the out skirts of the
village you will come across a sign, "Tarbert Tairbert" and you are
there. You can't miss it really, its M8 -> M898 -> A82 -> A83 all the
way to Lochgilphead->Ardrishaig->Tarbert!
Driving from Edinburgh to Ardrishaig
(a). The easiest way is to take the M8 to Glasgow and thereafter
follow the instructions as if you were coming from Glasgow.
(b). There is another way but it's good only if you know your way around, the
scenery is heavenly if it's not raining or snowing! Take the Glasgow Road, drive
past Edinburgh Airport and at the Newbridge Roundabout take and follow the M9
till you drive past Stirling, take left turn at Junction 11 on B824, drive past
Doune Safari Park and then take left turn on B8075, and then take a right turn
on A811 until you drive past Arnprior and Buchlyvie. Now a tricky bit, soon after
Buchlyvie you cross the A81. Simply turn left for a few meters and then turn right
still following the A811 until you come to Balloch where you drive through two
roundabouts and at the third roundabout make sure you join the A82 and drive along
to Tarbet (note the spelling) where you veer left onto the A83. Now follow A83
through Arrochar, Inveraray, and onto Lochgilphead. (Follow the A83 to Ardrishaig,
Tarbert and Campbeltown)
