Is there a way to get descriptions of great circle routes? Given that I am blind and love to know where I'm flying over, is there a online service that describes a great circle route in text form? e.g. in a format like this:


  A great circle from CYVR to LTBA goes NNE over British Columbia,
  Alberta, Northwest Territories and Nunavut, passing over Arctic bay in
  the northernmost part of Baffin Island. Then across the middle of
  Greenland, crossing the Atlantic to Norway then Sweden, passing abut
  30 miles west of Stockholm. Then across the Baltic Sea and over the
  Kaliningrad Oblast, which is the small exclave of Russia that sits
  between Poland and Lithuania. Then across eastern Poland, western
  Ukraine, Romania, the very corner of Bulgaria, across the very western
  edge of the Black Sea and arrives in Istanbul from NNW.


(thanks to @TomMcW who left this in my previous question).

This way I can stop asking these great circle questions here.
Thread
In your Manchester to Vancouver question, I wrote that a great circle is like a taut thread on a ball.
If you have a tactile (Braille) globe, get two pins and a thread. Place the pins on the departure and arrival cities, and wrap the thread around the pins so that the thread is taut. You can then follow along with your finger.
Coordinates
Another method is to go to Route Finder website.
Enter the departure and arrival airports ICAO codes (you can get them from Wikipedia). And plot the flight plan.
The generated flight plan will be close enough to a great circle. The waypoints will be listed by their latitude and longitude. The distance and track (heading) for each leg will also be listed.
