We are in Seoul for 6 weeks, and I have to say this is one of my BEST days so far. I took my 7 year old daughter, and we clocked 11 miles today and she was a champ!! We had Ray as our tour guide, and was just the absolute best. It was actually pretty crowded the day we went since it was a holiday weekend, but he helped us to navigate the crowds and went out of his way to make sure everyone was comfortable. My daughter even left her iPad in his car after he dropped us off at a meeting point. We panicked, called tripadvisor, and he drove it back 30 minutes later on his own time. What a guy!! He was also so knowledgable.
As far as the sights you will take in- BREATHTAKING! I have travelled all over the world, and this was just unbelievable. The cable car was full at Mt. Seorak, but instead Ray hiked us up to a waterfall that we wouldn't have had time to see otherwise. The views!!!
Nami island is a must do- it was just adorable and everything about it was magic.
DO THIS TOUR! You will not be sorry!!!!
If you are looking to get out of the city for the city for a day and experience nature, this is the perfect way to do it.
