I was fortunate to make the long walk (around 5km), easy to west, twice in the last week. Up from the east part, starting at Dongguk University Station and Jangchungdan Park up through Seoul Namsan Park to the tower and then down to Myeong-dong on the west site. It's strikingly beautiful a great climb, some steps are numbered, between those and the ones you don't count I imagine it's the equivalent to about 1,000 steps up the mountain and there are also a few steeper inclines. The steps, paths and roads are in excellent condition, everything is so clean and well signposted in many languages. You can also use N aver Maps to get you there.
The walk from Dongguk University Station to the base of Namsan Seoul Tower covers approximately 2.2 miles (3.6 km) with an elevation gain of about 797 feet (243 meters).
This route is one of the most rewarding ways to reach Namsan Tower, especially if you're seeking a blend of urban forest, cultural landmarks, and a bit of cardio. If you're up for it, you can extend your walk along the Namsan Trail network, which spans nearly 8 km across the mountain.
