They have lots of trains, lol. Apparently a very extensive subway system.
If I ever go, I will definitely try that out.
There is actually and easy? and rather inexpensive way to get there. A couple of years ago we flew to Canada, took Princes Cruise line up the Alaska coast, then they repositioned headed for The East and we stopped at Japan, Russia, South Korea, etc and the took a 4 day extension to Bejing. The cruise itself was around $2000 for 23 days and that included Alaska. I don’t think I can keep myself for that many days for $2000. But I will tell you there is nothing in the Berring Sea.
