There is a place on the northeast coast of South Korea called Seoraksan National Park. It is one of the most beautiful and challenging places that I have ever hiked, and I hope you get the chance to go there some day.
There are easier activities, like taking the cable car up to the top of one of the peaks, or enjoying tea in one of the temples.
There are even restaurants, and there are vendors along the trails.
If you are really ambitious though, there are some very difficult hikes that are completely and totally worth the effort.
The hardest of these hikes is a mountain called Ullsanbawi (above). It’s a long trail to start, and then so many stairs that you will loose count (I know I did!)
Sure, there is a temple to stop at along the way. There are places to get water. It’s a great trail that is well, worn.
However, the air is thin and it’s a long hike.
However, if you get to the top, it’s an amazing feeling.
Don’t go for just one day. The mountains make it very hard to predict what the weather will be like, and there is way too much to see in a day.
Instead, go for a weekend, or even an entire week. It’s a huge park with far more trails than I was able to do, and you can easily spend a week just hiking around.
Camping is permitted, but I stayed in the nearby village of Sokcho and took the bus in each day. I didn’t have a tent and all the gear needed to camp since I moved to Korea in suitcases.
No matter how long you go for, try to do one of the hard hikes. I didn’t have time for Dragon Ridge, but I am told it’s amazing as well. It’s really worth it for the views, which on a clear day extend all the way to the East Sea (or outside of Korea; the sea of Japan.)
