Hello this is Alice from Yeha tour.
First of all, Yeongsil is one of the hiking trails of Hallasan Mountain.
We are a travel agency that conducts a bus group tour.
We are cooperative company with the guest house, but a totally separate company.
By the text, I think you already have some information on the Youngsil course.
If you have any additional inquiries, please ask the guest house.
