We went with 3 people on this tour, and Yohan was the tour guide. Everything was perfect: always on time, the 7-seater car was new and clean, the ride was safe, the scenery was beautiful, and Jangtaesan is truly a place you shouldn't miss (there are a lot of locals coming here, not too crowded like tourist spots). Yohan accompanied us as a real seonsangnim leading the whole class on an outing (haha), and also as a driver-tourguide-photographer-local food reviewer!! He even sent all the naver map links to the restaurants during the tour (even when we ended the trip late due to traffic jam, he also sent us the dinner options near our drop-off point). I really recommend you to join this E-Autumn tour, the cost is completely worth it. The only downside seems to be that the leaves haven't turned yellow and red yet (because the weather this year the leaves turned late, I wish I came here 2 weeks later then everything would be perfect ๐
).
