Guy's you are reading my mind, I did water sports for 10 years and spent a lot of time round Loch Lomond. It's a stunning part of the world and i have a real soft spot for it.
Glencoe is a must, You will have never felt so small and insignificant driving through there. ( very humbling and a stunning landscape )
Olly, I know that road, It's tight in places and of course there is the sheep all over the place, But the view out over the sea loch's when your going back down the other side is stunning.
This all makes up a good first day...... Keep them coming lads.
I think the next question is how long do you want it run over, Do we just do a weekend ( two day's and one night stop ) and do a big loop. Or do we go longer ?
