The short answer
- Seoul is a city of 9.4 million people, yet mountains and rivers cut straight through it — and wild boars, raccoon dogs, water deer, otters and leopard cats really do live here.
- The only genuinely dangerous one is the wild boar. Everything else avoids people first — but never touch a raccoon dog (54.8% scabies infection rate).
- The rule for every situation is the same: don't run · don't feed · don't approach for a photo · call 119.
There’s a fact about Seoul most travelers learn last: this is a city with a surprising amount of wildlife. You won’t run into a wild boar in the middle of Gangnam, but the café streets at the foot of Bukhansan and the riverside paths before dawn are a different story. In 2025, Seoul firefighters were called out 494 times because of wild boars.
This guide has two parts: a field guide to the wild animals of Seoul up front, and a species-by-species survival manual at the back.
Why does Seoul have wild animals?
A huge share of Seoul is mountains. Bukhansan National Park blankets the entire north of the city, and Gwanaksan, Cheonggyesan, Achasan and Inwangsan are embedded throughout. On top of that, the Hangang and its tributaries — Jungnangcheon, Cheonggyecheon, Yangjaecheon — thread water through it all. In other words, Seoul is a city where mountains and rivers form a connected grid. For animals, that means habitat with guaranteed travel corridors.
The paradox: animal numbers rose because the city got better
Since the 2020s, Seoul has confirmed one apex predator after another — otters, leopard cats, Eurasian eagle-owls. In ecology, an apex predator settling in is read as a sign that the food chain beneath it is running steadily. It's the result of improved Hangang water quality and stream restoration. The rise in wild boar and raccoon dog sightings comes from the same place — populations grew, their habitats now press against the city, and the points of contact multiplied.
Who lives in Seoul? A field guide
On top of these: red squirrels and chipmunks (every park), weasels, moles, bats, pheasants, egrets and grey herons (in the shallow water of Hangang tributaries) — and snakes.

Met a wild boar? The 3 minutes that matter most
Straight to it: don’t run. Turning your back and bolting is the most dangerous thing you can do — it triggers a boar’s chase response. So does shouting, waving your arms, or throwing rocks.
Situation 1 — the boar has already seen you (eyes met)
- Stop calmly, keeping eye contact. Don't turn your back.
- Take cover behind the nearest tree, rock or utility pole.
- If an attack feels imminent, get to higher ground the boar can't climb.
- Hold a bag or other belongings in front of your body as a shield.
Situation 2 — the boar hasn't noticed you yet
- Make no sound and quietly back away the way you came.
- Don't try to take photos or video. Flash in particular is forbidden.
- Once you're safe, call 119 with your location.
When and where to be careful
Wild boars move mostly at night and at dawn. Seasonally, the danger peaks in late autumn to early winter, when food thins out, and in spring, when mothers travel with piglets. A sow with piglets is the most aggressive of all — if you spot a small boar, assume its mother is nearby and back off immediately.
In 2024, wild boar fire dispatches by Seoul district were: Jongno 113, Eunpyeong 111, Dobong 97, Gangbuk 86, Seongbuk 68. If you’re planning an early-morning hike or run around Buam-dong, Pyeongchang-dong, Jeongneung, Suyu or Ui, keep these numbers in mind.
Seoul has installed 184 capture traps and 18.8 km of barrier fencing to keep boars out of the city — and it’s working, with dispatches falling from 589 in 2024 to 494 in 2025.
Met a raccoon dog? The cuteness is a trap
The wild mammal you’re most likely to actually meet in Seoul is the raccoon dog. It strolls along streamside paths, apartment flower beds and under park benches without a care. It isn’t very afraid of people, so it may even approach. That’s where the trouble begins.
4 steps for a raccoon dog encounter
- Keep 1–2 m distance. If it approaches, you back off.
- Never touch it. And never feed it — a fed raccoon dog keeps approaching people until it ends up euthanized.
- Pick up your dog immediately. Dog-raccoon dog contact is the most dangerous scenario.
- If you see one with severe hair loss and gray, cracked skin (advanced mange), don't approach — call 02-880-8659.
If you’re bitten or scratched, wash the wound with soap and running water for at least 15 minutes, then go to a hospital right away. With post-exposure rabies shots, time matters.
Snakes — the real thing to watch on summer trails
Korea has four venomous snake species: the short-tailed mamushi (살모사), the Ussuri mamushi (쇠살모사), the rock mamushi (까치살모사), and the tiger keelback (유혈목이). All have been found in Seoul trail brush and Hangang Park wetlands. Most snakes avoid people first, but the viper group doesn’t flee readily — which is how accidental step-on bites happen.
Prevention — summer hiking basics
- Ankle-covering hiking boots and long pants. Most snake bites are to the ankle.
- Stay on marked trails; don't push into brush.
- If you see a snake, don't provoke it — wait at a safe distance for it to pass.
Want to see them on purpose? Seoul's wildlife-watching spots
If you’re after observation rather than risk management, Seoul has some genuinely good spots.
Bamseom — a Ramsar wetland in the middle of a metropolis
An uninhabited island under Seogang Bridge between Yeouido and Mapo. Designated an ecological landscape conservation area in 1999 and a Ramsar wetland in 2012. Alongside kestrels and eagle-owls (both Natural Monuments), it hosts endangered migratory birds like the white-tailed eagle, Steller's sea eagle, whooper swan, bean goose and white-naped crane. Public access is restricted — observe from the Bamseom Migratory Bird Observatory at the southern edge of Yeouido Hangang Park's wide lawn. Winter (November–February) is peak season.
Seoul Forest · Namsan Park — the easiest places to see red squirrels and chipmunks. Seoul Forest even has a free-roaming deer enclosure. Just don’t feed them.
Jungnangcheon · lower Cheonggyecheon — stretches where otter traces have been confirmed. Egrets and grey herons are almost guaranteed; with real luck, an otter at dawn. Otters are Class I endangered — if you find one, don’t approach, just watch from afar.
Where to report — numbers by situation
📞 Seoul wildlife contacts (including foreign-language support)

Found an injured animal? Don't hurt it while trying to help
- Before rescuers arrive, don't touch it or give food or water.
- Don't transport it in your car yourself. It's dangerous for both animal and human.
- Baby animals usually aren't rescue cases. A mother is often nearby, and she won't return while a human is present. If there's no visible injury, watch from a distance for a while before deciding.
The bottom line
Your odds of actually getting into trouble with wildlife on a Seoul trip are low. In Myeongdong, Gangnam and Hongdae, effectively zero. But if you’re taking a dawn walk in a Bukhansan foothill neighborhood, hiking in summer, or running along a Hangang tributary, this guide might just matter.
What to remember is three lines. Don’t run. Don’t touch. Don’t feed. And when in doubt, call 119.
