Sergiev Posad is an historical town with a cluster of churches and religious buildings an hour or so northeast of Moscow. It's a popular day trip, particularly with Chinese tourists, at least on the day I visited. Knowing that it's a popular day trip destination, I left Moscow early in the morning, early enough that I arrived in Sergiev Posad before some of the buildings were opened and grabbed a coffee. The drawback to leaving that early was that after spending two/three hours at the site, I was ready to return, and while it was easy to catch an early morning train out, there were not, unfortunately any mid-morning trains back. I'd need to wait another two plus hours for a train. I decided to take a bus and that was a bit tricky matching up the bus destinations with where the buses actually left - the bus terminal had quite a few gates. It's one thing to wait at a bus stop, it's another thing to pick the right bus among ten. I'm not sure if I picked the right bus or not, but was again thankful to have a cellular plan in Russia because I could hop off the bus when it approached a Moscow metro station and took the subway the rest of the way back to central Moscow.
