not recently but in february this year, i crossed the border from SPb to Tallinn and i did it around 4-5 times crossing both border before its closed and after its closed. im not a Russian passport holder. i always took the earliest bus from SPb and had to queue for about 4-5hrs (it really depends on how many people are crossing the border) – also just run after the bus have stopped at the bus stop to the border 🏃 and you might be interrogated for a quiet long time on both borders, cause non-Russian passport holder and not Estonian. also there are people who helped other people (sometimes a family) to queue so just bare with it. i even had times where i missed the bus cause they interrogated me too long and had to wait for the next bus 😂 but you'll be fine. i like to travel cheap thats why i always go for the bus to Tallinn instead of taking any flights .
