Irish citizens travelling to Turkey (and indeed citizens of most other countries) are required to purchase a visa for entry to Turkey (cost €15 per person).
Previously, this could only be purchased at the Turkish airport of arrival.
However, you can now avoid queuing and purchase the visa on-line on www.evisa.gov.tr/en/
You should note that if you purchase the on-line visa and subsequently change your departure dates to dates outside the validity period of your visa, or cancel your holiday, you will be required to purchase a new visa and will not be entitled to a refund.
