Depends where you are travelling to. If it's within the country or the EU then no i dont think so.
does my passport need to be in date to go to belfast
That would depend on where you are travelling from and your nationality. If you are arriving from mainland Europe you will need a Passport to enter. Anyone leaving the Country and returning needs a Passport.
yes just like everywhere else
Check with the ferry operators
Probably photographic identity such as a passport or suitable driving licence. Requirements depend on the ferry company.
Yes you do, even the travel to Ireland from the UK has now been restricted to passport holders only.
You don't need a passport as such but you will need an identification document with a photograph. Other documents such as a driving licence may be acceptable. This is not for entry to the Channel Island but to identify yourself to the air or sea ferry company transporting you.
No, Belfast is in Northern Ireland which is part of the UK - you don't need a passport to travel from one part of the country to another.
