Mt Seorak is very nice, calm and serene, we were given 2 hours due to the pack schedule, but it is quite good and I plan to visit it later when I return to Korea (the site is very bery large, and one site to another is quite far > 1 km walk) for hiking lovers this one is for u! Nami Island was okay, it is quite crowded, but the lake view is okay and nice if you have one day full to explore the island. But the highlight of the show is the Garden of Morning Calm, it is very very beautifullll and an underrated tourism spot. We were given only one hour, but ya its nice to know and you can visit and explore in another day! Guided and driven by Phillip, he is a funny guy, he is kind and cheerful. Overall, this tour is worth it for you to know other tourism spot outside Seoul, but if you want to explore another day it is very highly recommended!
