Would you recommend the TSE? We had planned to do it in a few years before it all kicked off
Sounds fascinating, but then thought it could be a lot of grass! ?
I'd say it's worth taking the trip but it's not the Orient Express. If you go in winter the train is boiling hot, there's only one heating setting. Most the stops are a bit samey, as is the landscape (we went from Moscow to Irkutsk then Irkutsk to Ulaanbaatar). Imo the landscapes get more interesting around Baikal and through to Mongolia. Some of the guards on the train can be pretty militant. I've also heard of people getting harassed by police at some of the cities on the route (although, this didn't happen to us).
Moving through time zones whilst on Moscow time is surreal. Lake Baikal is pretty special, amazing when frozen over. We did a two day dog sledging tour. Irkutks was a nice city, felt relatively chilled out.
Mongolia was a nice change in culture.
Not a huge fan of Moscow but I did enjoy wandering around Red Square and outside the Kremlin. The city is huge and it felt dominated by traffic.
The thing with Russia, it does feel a bit of a moody place, but once you break through language barriers (usually with a bit of vodka) they open up and are generally nice people. But be aware, they're not socially liberal. If you're not white and/or not straight, you'd need to take extra care.
Definitely glad I went but probably wouldn't go again on the TSE. I'd like to visit Saint Petersburg one day though.
