Gdanks to Kallininggrad

Hello, I’m planning to travel to St Peter from Kaliningrad and enter from Gdansk. Is this possible at all?

The full itinerary is Gdanks - Kalliningrad - ST Peter - Tallin - Stockholm

I was investigating this route recently. You should be able to take a bus from Gdansk to Kaliningrad. Then from there book a flight to St Petersburg. Rome2Rio had a bus service listed.

Polish company that operates the route and allows you to buy tickets online:

Yeah, that’s the plan.

But I couldn’t book the ticket for Gdanks - Kallininggrad in advance. Is it possible to just buy it on the spot?

@Irena Dziękuję
