Why Koreans Hike in Full Gear (And When You Need It)

The First Time a Client Asked Me About the Hiking Pants

A British couple I was dropping off at Bukhansan last May pulled on their shorts and trail runners while a group of Korean retirees shuffled past in Gore-Tex jackets, gaiters, and full trekking poles. One of the couple turned to me and said, 'Are they going up Everest or something?' It's a question I hear almost every week.

The honest answer is: those retirees probably know something your average foreign visitor doesn't. Korean mountain weather is genuinely punishing, the trails are steeper and more technical than they look on the map, and there's a very specific culture of preparedness built up over decades of people getting into trouble on these hills. But there's also a fair bit of fashion involved, and knowing the difference matters for your packing list.

Korea's Climate Makes the Case for Gear

The Temperature Swing Is Real

Seoul sits in a continental monsoon zone, which means the gap between valley temperature and summit temperature can be shocking. On a clear autumn day you might start a trail in Gapyeong at 22°C and hit the ridge an hour later at 10°C with a wind chill that cuts right through a cotton t-shirt. I've driven clients to Myeongseongsan in October who laughed at the Koreans in fleece at the trailhead, then shivered through lunch at the top.

Summer is the other trap. June through August brings the jangma (monsoon season), and afternoon thunderstorms on exposed ridges are not a small concern. The rain comes fast, the granite gets slippery, and trails that drain badly turn into streams inside twenty minutes. A waterproof shell isn't a style choice in July — it's the right call.

Winter Is Longer Than You Think

Korea's winters are sharp and dry. Trails above 600m can hold ice well into late March, and many popular peaks — Seoraksan, Deogyusan, Chiaksan — develop serious icy patches on north-facing slopes that last from December through to early April. Korean hikers know this and bring microspikes almost as a matter of reflex. I've had clients attempt icy sections in trail runners and turn back, which is absolutely the right call, but it ruins the trip.

The reason Koreans look so prepared is partly because they've been doing this for a long time and they remember the consequences of getting it wrong. Korea has a National Park rescue service (119) that responds to hundreds of calls every year, most of them from people who underestimated a trail's difficulty or the weather. The gear culture evolved as a direct response to real danger.

The Fashion Layer — Let's Be Honest About It

That said, not everything you see on Korean trails is strictly functional. Outdoor gear in Korea carries real social status. Brands like Blackyak, K2, and Kolon Sport are domestic Korean labels that cost serious money and are worn with visible pride. Matching sets — jacket, pants, gaiters, buff, and gloves all in the same colourway — are extremely common among hikers in their 50s and 60s.

I've driven clients past the outdoor gear street near Dongdaemun (there's a cluster of shops near [insert specific street name]) where you can watch Koreans spending 300,000–500,000 won on a single jacket without blinking. That price point is not about keeping warm on Bukhansan on a mild spring afternoon. Some of it absolutely is fashion, social bonding, and a particular generation's version of leisure identity.

Knowing this means you can calibrate. You are not going to be laughed off a trail in Korea for wearing shorts in August. What you will face is genuine, well-meaning concern from other hikers — and occasionally someone offering you snacks out of sympathy, which is honestly not a bad outcome.

When Foreigners Can Actually Dress Lighter

Spring (April–May): Yes, You Can Lighten Up

April and May are arguably the best months to hike in Korea, and you genuinely do not need a full kit for most trails below 1,000m. Temperatures are mild, the trails are dry, and the azaleas are out on peaks like Sobaeksan and Hwangmaesan. I would still recommend a light packable layer and proper grip shoes — wet granite is everywhere — but you can leave the insulated pants at home.

Summer Weekdays on Lower Trails: Keep It Simple

On a weekday in June, on a trail like Yongmasan or Acha Mountain in Seoul, shorts and a moisture-wicking top is completely fine. These are not technical mountains. The heat is the actual enemy, not the cold, and you'll see plenty of younger Korean hikers dressed similarly. Bring water (more than you think), a hat, and sunscreen. The sun bounces hard off granite.

Where I'd draw the line is multi-day routes, anything above 1,200m in summer, or any trail during or after heavy rain. The jangma swells creek crossings and destabilises slopes, and that's when the full gear crowd turns out to be completely right.

Autumn (September–November): This Is When Gear Earns Its Place

Autumn foliage season is the most popular hiking period in Korea and, for my business, the busiest time of year. The crowds on peaks like Seoraksan and Naejangsan are extraordinary — I've dropped clients at Baekdam-sa at 6am and the car park was already half full. The weather is also the most unpredictable of the year.

Warm at the trailhead, cold at the top, possible afternoon rain, wind on exposed ridges. For autumn, I tell every client: bring a proper waterproof shell, a mid-layer, and shoes with actual grip. This is not the time to test whether your gym trainers are 'basically fine.' The trails are beautiful and they demand respect.

Winter: Match the Koreans, No Argument

If you are hiking above 500m between December and March, dress like a Korean. Thermal base layer, insulating mid-layer, waterproof shell, gloves, a hat, and microspikes in your bag. I sell a basic microspike rental add-on through Off Map Korea precisely because clients arrive in January thinking the trails look fine in photos and then encounter a solid sheet of verglas fifty minutes in.

Microspikes can be bought at most outdoor shops near major trailheads for around 20,000–40,000 won for a basic pair. It's worth buying rather than renting if you're doing more than one winter hike.

What the Gear Culture Tells You About Korean Hiking Values

Hiking (등산, deungsan) has a special place in Korean leisure culture that goes beyond exercise. It's deeply communal — the mountain huts and rest areas on popular trails are full of people sharing food, pouring shots of makgeolli, and sitting together for an hour before heading back down. The gear is part of showing up properly, the same way you'd dress appropriately for a meal with someone's parents.

I've watched my clients get drawn into these trail-side gatherings. A retired couple from Daejeon shared their entire packed lunch with two guests of mine on Gariwangsan last autumn, handed out homemade jeon (savoury pancakes), and asked absolutely nothing in return. The gear, the preparation, the snacks — it's all part of the same impulse to treat the mountain seriously and treat the people on it generously.

A Practical Packing Summary

• Spring (Apr–May): Light layers, packable rain jacket, grip shoes. Skip the heavy insulation.
• Summer (Jun–Aug): Moisture-wicking top and shorts for low trails, full waterproof shell for anything above 900m or during monsoon.
• Autumn (Sep–Nov): Mid-layer, waterproof shell, grip shoes minimum. Treat every forecast with suspicion.
• Winter (Dec–Mar): Full thermal system, waterproof shell, gloves, hat, microspikes. No exceptions above 500m.

You don't need 400,000 won worth of Blackyak to hike in Korea. But you do need to understand why it's there — and on certain days, on certain mountains, you will be genuinely glad the person next to you is carrying everything they brought.

One Last Thing

Every time I see a client smirk at the fully kitted-out retirees at the trailhead, I think about a solo hiker I picked up from Dobongsan one October evening — soaked through, slightly hypothermic, and very grateful for the emergency poncho I keep in the car. He'd started the day in a t-shirt because the weather app said 19°C. It did say 19°C. At 7am, in Seoul, at sea level. The ridge had other ideas.

The Koreans in Gore-Tex had a great day. He had a story he tells at parties. Both are valid outcomes, but only one of them involves shivering.
