7 gorgeous Korean mountain hikes

7 gorgeous Korean mountain hikes

Hiking some of Korea's mountain tracks is a visual treat in fall and winter
Hiking Korea's mountains in the autumn
With 398 square kilometers of UNESCO-designated biosphere, Seoraksan National Park has more than a few gorgeous gorges vying for attention.

It would be a shame to visit Korea without clambering to the top -- or at least along the slope -- of one of the country's many, many mountains. Korea was blessed with a shapely topography: 70 percent of its landscape is mountain (the other 30 percent, expensive coffeeshops).  

Around this time of year, due to the startling colors of the curvy landscape, the trails will doubtlessly be packed with streams of hikers in garishly colored hiking gear, sometimes smelling like soju. 

But there are also many paths to the top of the mountain (literally), and many excellent paths that don't necessarily lead to the top.

Here's where to check out the most vibrant autumnal hues or, later in the year, the bleached landscape of a snowy mountaintop. 


1. Seoraksan 

Hiking Korea's mountains in the autumnSeoraksan is not South Korea's tallest or prettiest mountain, outranked by Hallasan and Geumgangsan, respectively. But it is nonetheless one of the most beloved.

At 1,708 meters, Daecheongbong is Seoraksan's highest peak, and a favorite with novice mountaineers. 

Depending on where you begin your journey, the trek to the top can be done in as little as three hours. Lower down, the popular Cheonbuldong Valley explodes into a riot of color come autumn. 

But the two-hour trek to the top of Ulsan Bawi (876 meters) can be particularly rewarding, not just for the physical exercise, but also the sensational views of the eastern sea, Daecheongbong and the valleys below.  

You can start from Sinheungsa, near the Kensington Star Hotel. 

According to the Korea Meteorological Administration, fall foliage on Seoraksan peaked on October 17 this year. The colors generally hold until late October, however.

2. Bukhansan 

Hiking Korea's mountains in the autumnFrom Baegundae you can see neighboring peak Insubong (804 meters), like a mound of ice cream.

Seoul, amidst its urban sprawl, has seven mountains.  

But the greatest of these is perhaps Bukhansan, sometimes called the "lungs of Seoul" for the role it plays in helping clear out that CO2. 

The three-hour hike up to Baegundae, Seoul's highest peak (836 meters) beginning from the Bukhansanseong Hiking Support Center near Gupabal Station (subway line three), is one of the most popular trails.

And for good reason: steep enough to keep your feet busy, with a superb bird's-eye view of Seoul, it's still perfectly doable for even the casual weekend hiker. 

The peak date for fall foliage is October 26

3. Taebaeksan

Hiking Korea's mountains in the winterFor the less religiously inclined, the stacked stones of Cheonjedan may not seem particularly impressive visually, but the "snow flowers" should more than make up for that.

Dangun, the legendary founder of Korea's ancient kingdom Goguryeo, was supposedly born on a mountain called Taebaeksan. On the 1,567-meter highest peak, Janggunbong, there's Cheonjedan, "altar for heavenly rites," where, in an earlier time, the devout would perform rites to honor the gods.  

Taebaeksan really blooms in the winter when the branches sparkle with frozen snow. In Korean, the sight is literally referred to as "snow flowers." 

Its autumns, however, are sadly underrated. While less monochromatically striking, autumn weather makes for good walking, and Taebaeksan's leaves are also a-changing. 

Despite its height, the way up to Janggunbong is more of a gentle slope than a craggy scarp; getting there should not take more than two hours from the Baekdansa (Baekdan Temple) entrance.

4. Songnisan 

Hiking Korea's mountains in the autumnSongnisan means, "to leave mainstream society." Perhaps a bit exaggerated, but yes, we get it: it's beautiful.

The most important thing to know about Songnisan is that it's a damn good-looking mountain. 

In autumn, the leaves die in varying shades of scarlet alongside the weird and wonderful rock formations that make up Songnisan's cliffs. 

The highest peak is Cheonwangbong at 1,058 meters, but the loveliest is cloud-shrouded Munjangdae at 1,054 meters. The view from Munjangdae is also spectacular, and if you start at Shilla-era Buddhist temple Beopjusa, you can get there in three hours. 

Tip: Beopjusa also has a Temple Stay program, if you'd like to "leave mainstream society" for a bit longer than an afternoon trek. It's also home to the peninsula's largest Buddha statue, 33 meters of wisdom incarnate covered in gold leaf. 

The fall foliage peaks on October 26

5. Jirisan  

Hiking Korea's mountains in the autumnEver wonder where photographers for calendars of unrealistically pretty mountain vistas go for their material? You can't Photoshop this kind of stuff.

The granddaddy of Korea's mainland mountains, Jirisan is huge. The park that encompasses the mountain's many peaks is Korea's largest national park (484 square kilometers). The highest peak, Cheonwangbong (1,915 meters), is second only to Hallasan. 

But one of the best places to really get into the spirit of autumn is in the valleys, such as the spectacularly beautiful Piagol Valley to the south. You can begin at Yeongok Hiking Support Center and walk the entire length (five hours), or linger in place to gawk. 

The fall foliage peaked on October 18, but the valleys, which change later than the peaks, should still have some red left in them for a few weeks yet.

6. Naejangsan

Hiking Korea's mountains in the autumnSeasonal makeovers have a way of transforming your average mountain.

On its own merits, it might seem like Naejangsan doesn't really have a place on a representative list of South Korean mountains. Sinseonbong, at a measly 763 meters, is its highest peak. 

But Naejangsan's yearly transformation is so radiant that it has been known has fall foliage central for approximately 500 years now. 

The most commonly traversed course is the three-hour walk to peak Seoraebong from the Hiking Information Center, but the show starts before that.

On the walk from the Hiking Information Center to Buddhist temple Naejangsa you come across an avenue lined with 108 densely-packed trees, decked out in all manner of golds, oranges and reds. 

All this fall foliage is due to peak on November 6.

7. Hallasan

Hiking Korea's mountains in the winterOne way to (possibly) avoid crowds: Go when it's really, really cold and slippery.

Hallasan, a volcanic mountain that makes up most of Jeju Island as well as South Korea's tallest peak (1,950 meters), is also more of a winter player.

But that doesn't mean you can't appreciate its autumns (as well as the volcanic cones or lava flows that also decorate the landscape). 

Many visitors start at Hallasan National Park’s Visitors Center and make their way up along the Eorimok Trail, but this trail won't take you to the peak, where Baeknokdam, the crater lake at the top, awaits. 

The Seongpanak Trail, which starts at Seongpanak, to the east, will take some patience -- five hours' worth -- to complete, but it takes you to the lake. 

Fall foliage is due to peak on October 30
