Seoraksan National Park

Seoraksan is one of my personal favorites and its also one of the most popular for visitors to visit from Seoul. Its known for having dramatic mountain peaks, waterfalls, beautiful fall colors, and there’s plenty of day trips you can join if you don’t want to go alone.

Bukhansan National Park

If you’re staying in Seoul and want to experience a national park without traveling too far, then Bukhansan National Park is another great option. You can experience the beautiful contrast between the city and the natural landscapes and there’s plenty of hikes and walks to enjoy, like this guided hike to the summit.

Hallasan National Park

Hallasan National Park is located on Jeju Island, so it can be a little harder to get to than the parks around Seoul. The main attraction is Hallasan, the highest mountain (technically, a dormant volcano) in South Korea. There’s a few different hiking routes, and the landscapes change drastically during the seasons, but if you want a guided hiking experience this is a great option.
