I'm helping to plan an approximately 10-day trip for my father (age 75) and my sister and her husband. (I, alas, will stay home and live vicariously through the planning).
Roughly, I'm thinking to start in Edinburgh, then up through the highlands to Inverness, across to Skye, down through to the Trossachs/Loch Lomond area. Attractions favored would be a castle or two, some historic battle sites, quaint villages and lots of scenery.
Travel by train is most attractive, but I know you need a car to see some of the specific sites. Is it possible to combo it and if so, what would you recommend? Years ago we bought a rail/drive pass. Are such things still available?
I suppose we don't want to stress everyone too much with trying to drive everywhere. And also recognizing that my Dad won't be into hiking and long walks (although he held up well in London last year!).
Thoughts? I'm going through the visit scotland and visit highlands sites for background.
