8) What are the entry requirements for Turkey?

You'll need a tourist visa to travel to Turkey. You can apply for a visa online at www.evisa.gov.tr before you go - E-visas can be applied for up to 3 months in advance of your travel date. It costs US$20, payable by VISA or MasterCard debit or credit card only.

If you need assistance applying for your visa, we recommend the Travel Visa Company. That said, other suppliers are also available.

Self service e-Visa kiosks and Wi-Fi areas where visitors can apply for an e-Visa on arrival are no longer available in Turkish airports - you must apply for your e-Visa before you travel.
Passport validity - Information taken from the gov.uk website 

Your passport will need to be valid for at least 6 months after the date you arrive in Turkey and at least 3 months after the date you leave the country. 

From the 1st January 2015, when you arrive in Turkey your passport must also be valid for 60 days beyond the expiry date of your visa or residence permit.
