Where to start in Kyiv
Kyiv Central Bus Station is at 1/2 Nauky Avenue, near Demiivska metro station. Kyiv-Pasazhyrskyi railway station is at 1 Vokzalna Square. These are separate places; allow a realistic transfer if arriving by train. International operators can use another Kyiv stop, so the ticket takes precedence over the general station address.
Porto's Campanhã interchange
The Terminal Intermodal de Campanhã (TIC) coach terminal is on Rua de Bonjóia, 4300-084 Porto. Porto-Campanhã railway station has its entrance at Largo da Estação de Campanhã, 4300-173 Porto. The terminal connects with the railway and metro, but they are distinct entrances: follow signs rather than assuming the coach bay is at the railway forecourt. Check the final arrival stop on your ticket, as not every service uses TIC.
Before travelling
Compare the available options for your date by changes, total duration and luggage rules. Leave time for border checks and possible traffic delays, especially before a separate onward ticket. Check entry and transit requirements through official sources; a direct or daily coach is not guaranteed.
