Absolutely amazing experience. Dont be deterred by the little reviews, YB our tour guide was really welcoming and knowledgeable. We had a small group of 6 and YB drove us around in his comfortable van. Every stop we got to spend the perfect amount of time in. It is a really long day, but definitely worth it. Each destination was breath taking and YB would tell us facts about the history. If you are in Busan and want to tick all the boxes for the "must see sights" then I recommend you do this tour. THANK YOU YB, WE HAD SUCH AN AMAZING TIME!
