Avtovokzal

(information verified by experience personally) If you want to leave Bolgar for Kazan back, the first step is to take the driver's phone immediately upon arrival, agree with him about the departure, and if something goes wrong, call him right away. There is no schedule as such, the bus driver picks up everyone with whom he agreed for a certain time, the price in the opposite direction is the same.

Good place, you can buy something and leave)

Only buy a ticket and wait until the bus in a small room on the seats, there are not enough places, there is no terminal for bank cards, it is impossible to pay by card, only in cash.

Scantily, there is nothing but a box office window and a couple of shops. It opens only when the cashier arrives, the rest of the time people are standing on the street.

The central bus station does not look neat.
