Korea Trekking Gear List: Why I Pack Extra Socks

The Day One Wet Sock Derailed an Entire Mountain

It was a Tuesday in late October, and I had just dropped a couple from Toronto at the lower trailhead of Jirisan's Baraebong ridge. The forecast was clear, the autumn colours were at their absolute peak, and they had a solid seven-hour loop planned using the printed guidebook I give every client. I drove around to the far side to wait at the agreed pickup point and found a café to sit in. Everything was fine.

Three hours later my phone rang. They'd had to turn back. The woman had stepped into a deceptively deep puddle on a narrow section of trail just past Seseok Shelter, soaked her right foot through to the skin, and within ninety minutes the combination of cold air and wet wool had given her a blister the size of a two-hundred-won coin on her heel. The ridge walk — the whole reason they'd come to that part of Gyeongnam — was over before noon.

I felt terrible. Not because I could have carried her across the puddle, but because I had a dry pair of socks sitting in a ziplock bag in my boot the entire time, and I had never once thought to mention it as they stepped out of the car.

That was the last time that happened. Now every client gets a dry pair before they start walking. And it prompted me to write up the full gear list I give to people before they fly to Korea.

Why Korea Trekking Gear Is a Slightly Different Problem

Korea's mountains are not the Himalayas. You are rarely far from a shelter or a staffed sanjangniji (mountain hut). But they are steep, the trail surfaces vary wildly between polished granite slabs and muddy forest floor, and the weather windows can flip fast — especially on Hallasan, Deogyusan, and the Yeongnam Alps. Altitude alone isn't the hazard. Moisture and friction are.

Most of my clients arrive having packed sensibly for a city holiday and then added 'hiking shoes' as an afterthought. That's usually fine for a four-hour forest walk. It's not fine for a full-day ridge traverse on Gakwhabong or a tidal-flat crossing to reach an island trailhead on the West Sea.

The other thing that catches people out: Korea's convenience stores near trailheads are excellent, but they do not stock hiking gear. You can buy energy drinks, kimbap, instant ramyeon, and rain ponchos. You cannot buy merino socks, blister plasters, or a spare headlamp. Plan accordingly before you leave your hotel.

The Core Korea Trekking Gear List

Footwear and Socks — the Non-Negotiables

• Waterproof trail shoes or low hiking boots. Proper ones. Not trail runners you bought two years ago with the Gore-Tex lining worn through. The granite on peaks like Wolchulsan and Bukhansan is polished and slick when wet; you want rubber with grip.
• Two pairs of hiking socks per day. This is the lesson. One on your feet, one in a ziplock in your daypack. Merino wool or a synthetic blend. Not cotton. Never cotton on a long descent.
• Blister plasters (the cushioned kind, not thin fabric strips). Compeed or equivalent. Take more than you think you need. A 20,000-won box from a Seoul pharmacy before you head south is worth every coin.

Clothing Layers

• A wicking base layer. In summer this is everything. Korean mountain humidity in July is oppressive; cotton kills your energy faster than the gradient does.
• A lightweight fleece or insulated mid-layer. Even in August, the summit of Hallasan at 1,950m can be cold enough that standing around in a sweaty t-shirt is genuinely unpleasant.
• A packable waterproof shell. Not a poncho. A proper jacket with a hood. Korea's afternoon storms in summer arrive with almost no warning and bring sideways rain. A rain poncho catches the wind and becomes a sail on an exposed ridge.
• Sun protection. Hat with a brim, sunscreen, and consider a UV buff for the South Sea island walks where you're on open coastal path with no shade for hours.

The Daypack Itself

• Twenty to twenty-five litres is the sweet spot for a full-day mountain walk in Korea. Enough for layers, lunch, and water. Not so big that it throws your balance on a narrow ridge scramble.
• A pack rain cover matters more than people expect. Even if your pack claims to be 'water-resistant,' Korean downpours are serious. Your extra socks need to stay dry.

Water and Food

• Most major Korean national park trails have marked water points where spring water is tested and declared safe to drink. The guidebooks I give clients mark these. Don't rely on them exclusively, but they do reduce how much you carry up.
• Carry at least 1.5 litres from the trailhead. In summer, 2 litres minimum.
• The convenience stores near most trailheads stock triangle kimbap, banana milk, and energy bars. Pick up snacks there rather than hauling food from Seoul — it's cheaper and fresher. But do not expect them to have a hot meal at 6 a.m. when you need to start early. Eat properly before you leave.

Navigation and Safety

• Korea's national park trail signage is genuinely excellent in Korean. English transliterations are present at most major junctions but not all. The printed guidebook I send clients before each trip covers every junction, distance marker, and shelter along their specific route — that's the navigation tool.
• A fully charged phone is critical. Not for Google Maps (which works reasonably well but struggles on some island routes), but because emergency services in Korea's national parks operate through a system where your GPS coordinates can be reported via the 119 app. Download it before you go into the hills.
• A small headlamp, even on a day walk. Descents in autumn and winter can run long. Dusk comes fast in the valleys.
• Trekking poles. Optional for gentle forest trails, strongly recommended for the steep granite descents on Seoraksan, the Yeongnam Alps, or any route above 1,200m with significant elevation loss. Korean rental shops at some major trailheads carry them, but supply is unreliable. Bring your own if you have them.

Things Korea Specifically Throws at You

The Trailhead Problem

A significant number of the trailheads I drop clients at have no facilities of any kind. No toilet block, no vending machine, no shelter. This is especially true for the less-visited routes on mountains like Mindungsan in Gangwon, Gageodo's coastal ridge, or the quieter approaches to Deogyusan. By the time you realise you've forgotten something, I'm already driving away. The gear needs to be in the pack before you leave the accommodation.

The Descent Is the Dangerous Part

Korean peaks tend to be steep-sided. The ascent is hard on the lungs; the descent is hard on the knees and hard on the socks. Long, sharp granite descents create friction points that don't exist on the way up. This is the primary blister and knee-pain scenario I see. Poles help. Fresh socks at the summit — swapped out from the ziplock bag — help more than most people expect.

Seasonal Mud and Ice

Spring thaw on north-facing slopes means mud that will pull a shoe off if you step wrong. Winter approaches — even on mid-altitude routes — can have ice patches that are invisible from above. Microspikes (a compact slip-on crampon) weigh almost nothing and have saved several of my clients from very bad mornings on routes like the Cheonwangbong approach to Jirisan in February. They're not always necessary, but when you need them, nothing else substitutes.

What I Now Keep in the Car Boot

After the Jirisan incident I started keeping a small emergency kit in the car: two pairs of spare hiking socks in ziplocks (sizes M and L), a roll of blister tape, a basic first-aid pouch, a spare headlamp with fresh batteries, and two emergency foil blankets. I've used the socks six times. I've used the blister tape more times than I can count.

If a client calls me from a trailhead because they've forgotten something critical, I can sometimes drive back — depending on where we are. In the remote valleys near Gurye or on the back roads behind Namwon, that round trip might take an hour. An hour you don't have when you've got a ferry to catch off Gogunsan.

The gear list above won't add more than a couple of kilograms to your luggage if you pack it properly. The cost of replacing a ruined day — the flights, the accommodation, the time you can't buy back — is a different order of magnitude entirely.

A Final, Personal Note

The Toronto couple came back the following spring and did the Baraebong ridge properly. She wore two pairs of socks. I handed her a third pair when she stepped out of the car, told her to put one in her bag for the summit, and said nothing else about it. She laughed. Seven hours later I picked them up at the far trailhead, both of them mud-stained and completely satisfied. She had not opened the backup pair. That is exactly the outcome I want every time.
