I'm a total nerd, so when I saw this incredible opportunity on Klook, I just had to geek out and grab it. And, honestly, I'm stoked that I did. The entire experience was ridiculously awesome, and achieving way more than I thought possible in just six hours, including lunch. The cherry on top was having the tour all to ourselves, making it feel like a VIP experience. I'm giving our tour guide and driver a standing ovation, so if you're ever in Busan, I highly recommend taking the leap and experiencing it for yourself.
