The host/guide was so knowledgeable about the mountain and specific details about Korea's history. It is special, too, that he used to be a history teacher. More than this, Wooyung is kind and interested to listen to my side of the stories. He was also patient in allowing me to hike at my speed. He is a perfect hiking guide that allows you to discover relevant aspects of the mountain, tigers that used to roam the place a hundred years ago, the role of the mountain in Seoul's history, the kind of community that lived at the foot of Mt. Ansan...and everything you needed to know. I wish he had other tours, I would join them again. Thank you for making this climb one of the highlights of my Seoul trip! Oh did I say, he is also kind enough to take great photos. Maraming, maraming salamat! in my language, that's thank you so much.
