Day trip from Kazan to Bolgar?

[tupacshakaur]

Hi,
I will hopefully be in Kazan in mid June for the World Cup. I am planning on spending a day or two in Kazan the city itself. But I also want to take a day trip to Bolgar. A few questions:

1-Are there nice ferries that go there and bring you back? Or is bus a better route?

2-How long should we spend in Bolgar?

3-Mid June weather, will it be very hot or a warm or mild weather?

Please help.
Thanks!

I didn't find the right solution from the Internet.
