Born in İstanbul, Nilgün Ergüç studied in the French Highschool and then the American Highschool of Istanbul. She continued her studies in Economics and the Engineering of Business Administration for her MA. She is still a student in the Marmara University preparing her PhD on international relations.
Although she worked in different fields for a short time, each time spring came and the judas trees blossomed, she wanted to escape the offices and be lost in her beatiful city Istanbul. She got her guiding licence in 1983. Since then she guides in Turkish, French and English in Istanbul and Turkey.
