"Hot spring tourism is very popular, especially during the winter," he said, adding that swimming in the outdoor pool while snowing is a pleasure.
Aiming to increase the number of visitors in 2020, he said Russian travel guides who enjoyed their trip in Yalova, have advised others to visit.
Russian vacationer Valeriya Dobrotina said she heard about the facility through social media.
"My friends, who already visited there, advised me to visit. I really liked the place. I want to visit there one more time," she added.
