You will have no doubt heard that Greece is facing a banking crisis because of a possible forced exit of the euro.
Athens ordered its banks to close after a referendum on Sunday, with ATM withdrawals limited to €60.
At this stage this limit is not being applied to non-Greek bank accounts, but this could change very quickly.
Over 2 million British people travel to Greece each year, so here is some Greek travel advice.
If you are going to Greece in the next few days, check the official government travel advice.
It would be a good idea to make sure you travel with enough ready cash.
The euro is likely to be accepted where ever you are in Greece.
Check with your travel insurer about the limit of cash you are covered to carry, and bear in mind that this might be per person.
You could also think about using pre-paid credit cards, or ordinary credit cards, and to keep the cash you are carrying for emergencies. Do think about any credit costs.
Don’t forget to make sure you’ve got your European Health Insurance Card – available from the government website, for free. This entitles you to be treated throughout the European Union (and EEA) on the same terms as local citizens. Beware of websites that are charging for this free service.
The government website is also warning travellers of the risk of travel and services being disrupted because of sudden strike action.
