Is there a way to get descriptions of great circle routes?
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.
