I am visiting a friend at the beginning of November in Seoul. There will be 3 20-something women, and we would like to take a couple day/overnight trips outside the city. One day we definitely want to spend "in nature" of some sort, whether that be hiking in a national park or going to a rural area or seeing some sort of natural wonder. The other day is just anything cool. We're not into the beach/islands...
Any ideas would be amazing, thanks!!
