September 2019 Scotland Itinerary

Hi there
This looks perfectly doable in 10 days. My only suggestions would be
a) you'll be backtracking across county from Kingussie to Glenfinnan. Better to go Glasgow - Glenfinnan (possibly using Fort WIlliam as a base)
b) I wouldn't have thought Kelso was a particularly good location for day trips to Edinburgh. Stirling might be better for ease of getting into Edinburgh. And there's the bonus of the castle and Wallace Monument.
c) Pitlochry would be a good base for Kingussie area.

Hope this helps.

I’ll just suggest that you try to relax and enjoy yourselves. Be aware of that weird tension that grows in a group when you’re trying to pack too much into a day.

There’s plenty to see and do but there’s also plenty of lovely country to just sit down and look at. For instance, along the road through Glencoe, a short hike will get you far from the crowds in the parking lots.

We did not have time to ride the steam train but I should think you would want to book that excursion well in advance. I enjoy ancient and scenic Scotland but I appreciated a quick stop outside Falkirk to view the contemporary sculptures. The Kelpies can be toured on the inside, another interesting thing we just did not have time for.

-- Edited -- I'm relieved to see that you're planning 2-3 days in Glasgow before setting off in your rental car. --

I'd strongly advise spending your first night much nearer to Glasgow airport, and not driving the A9 while jetlagged. You may intend to sleep on the plane, but you will not get a normal night's sleep and your interior clock will be thrown off. Jetlag is basically the equivalent of being drunk when it comes to executing the tasks involved in driving -- let alone driving on the left.
Plus, in September, depending what time you get out of the airport and obtain your rental car, it could very well be dark.
It would be fairly easy to take public transportation from Glasgow airport to Falkirk. You could stay the night there and visit Falkirk's sights on the 14th. Then you could rent your car out of Falkirk.

Navigating from the airport (which is actually in Paisley) to Falkirk would be enough of a challenge. I would not recommend trying to make it all the way to Kingussie.

Thanks for the suggestions! And btw, we’ll be spending 2 or 3 days in Glasgow before heading out in the rental car.
