While the number of tourists -- both domestic and foreign -- visiting the site in 2018 was 100,000, the number rose almost two-fold this year, Demirel said.
"We believe that this number will continue to increase in the upcoming years," he said.
The hot air balloon operations will be held in 2020 in Ankara, Afyonkarahisar, and Eskişehir, he added.
According to UNESCO, Phrygia is a civilization which existed in 800 B.C. and dominated central Anatolia from the Mediterranean Sea at the south and Black Sea at north.
"Along the deep valleys in the region, castles, mounds, tumulus, necropolises, rock-cut worship places, inscriptions and reliefs, altars, cisterns, monumental rock-cut tombs, and niches have been found as testimonies of Phrygian culture," UNESCO said stressing that other exhibits also justified the worthiness of the place.
There is also a 506-kilometers-long (314 miles) trekking and cycling path (Phrygian Road) on the site which was constructed without harming the historical milieu.
The ancient site was named "the second Cappadocia" due to its landscape.
