Sergiev Posad (Russian: Сергиев Посад) is a city in North Moscow Oblast, which is famous for its Troitse-Sergeeva Monastery, the spiritual home of the Russian Orthodox Church. It is often visited as a part of the Golden Ring around Moscow.
Trains leave every 30 minutes between Sergiev Posad and Moscow's Yaroslavsky train station. The station is located at Komsomolskaya metro station (red line). A ticket to Sergiev Posad costs 132 roubles (1.5 hours, prices in 2011) and 181 roubles on express (5-6 times a day, 1 hour). It is an easy day trip from Moscow.
There is a bus (388) available at VDNKh (VVTs). Ticket price about 120 roubles. Leaves every 15 minutes. However, be aware of jams about from MKAD to Pushkino almost always in rather extended rush hours.
To get to the town by car take Yaroslavskoe highvay from Rizhski Vokzal (Rizhski train station) or VVTs (VDNKh) - it takes approximately 2 hours to get to Posad: distance is 70km (40 miles), however see above about jams. Construction of new intersection between Korolyov and Mytishchi simplified things with the jam a little, but parts of M8 highway before and after intersection are still crowded because of bottlenecks closer to MKAD and in Klyaz'ma village.
The main tourist spot is the monastery. It can be seen from station and can be reached by foot in about 10 minutes.
The reason why one should see the city is the monastery. The monastery of Sergiev Posad is one of the most beautiful monasteries in Russia and one of the principal spiritual centers of the Russian Church. It is a combination of a fortress and a monastery. The seminary of the Russian Orthodox Church is located in the buildings of the complex. There are several churches to see, a holy source and in general the whole complex with its massive walls and gates is very picturesque. There are no admission price to pay except for the museum, which shows old religious objects and woven pictures of saints. At the weekend the monastery can get very crowded, as it hosts some very important icons (at least copies of them). In return it can be very interesting to observe the believers kissing the icons and praying for hours.
The grave of Boris Godunov (of Pushkin's play and Russian history) and some family members is also located here.
There is a restaurant called Rusky Dvorik (Russian courtier) which is quite good, but also expensive taking into consideration the general price level of Russian province. It is located just in front of the entry of the monastery.
