If you ask Google Maps to give you directions from Snowdon to Brecon Beacons in Wales, it'll estimate travel times whether you are traveling by car, bus, on foot, plane, bicycle, or dragon.
If you select dragon, Google Maps helpfully informs you that the estimated travel time is 21 minutes. That's fast! It also shows a dragon icon which is strikingly similar to the one on the Welsh flag.

That appears to be the only dragon route available. For example, if you want to travel between Gun Barrel City and Cut and Shoot (two towns in Texas), then you don't get the dragon option. That strikes me as a serious oversight.
