Practical Information for visiting Chungcheongnam-do

Coverage for mobile networks is excellent everywhere, with 5G throughout the province — South Korea has among the best mobile infrastructure in the world.

Prepaid SIM cards and eSIMs are easy to obtain at Incheon airport or in convenience stores with a passport, and data is cheap and fast.

Wi-Fi is free and widespread, including on trains, buses and in public buildings.

Signal reaches the islands and the mudflats, and drops out only in the deeper valleys of Gyeryongsan.

Power is reliable throughout, on 220 volts with European-style round pins.

Many services and tickets assume a Korean phone number or app, which is worth planning around.

South Korea is one of the safest countries in the world, and this is one of its quieter provinces. Crime against visitors is very rare, and the real hazards are natural.

• The tides are the serious one. With a range of over eight metres, the sea returns across the mudflats faster than you can walk, and people are cut off and drowned every year. Check the tide table, and go out with someone who knows the ground.
• Traffic: crossings are generally orderly, but scooters on pavements and drivers turning on red both catch visitors out.
• Summer heat and humidity, and typhoons between July and September.
• Air quality in spring, when fine dust warnings are issued.
• Hiking: Gyeryongsan is steep and busy; start early and carry water.
• Winter ice on mountain trails.

South Korea has excellent, modern and inexpensive healthcare. Visitors pay but the amounts are modest by Western standards, and travel insurance is still sensible.

No vaccinations are required beyond routine cover; hepatitis A and typhoid are sometimes suggested, and Japanese encephalitis for long rural stays.

Air quality is the most likely health concern: fine dust and yellow dust episodes in spring can be severe, and a proper mask helps if you have any respiratory condition. Forecasts are published daily and taken seriously locally.

Tap water is safe to drink, though many Koreans drink filtered or bottled.

Raw seafood is widely eaten and generally safe, but raw shellfish carries some risk; the cured crab is safest from a busy specialist restaurant.

Pharmacies are everywhere and staff are competent; some medicines common elsewhere require a prescription here.

Remove shoes when entering homes, temples, guesthouses and any restaurant with a raised floor.

Two hands for giving and receiving anything — money, cards, a glass — particularly with someone older.

Drinking: never pour your own, pour for others, and accept the first glass offered.

At temples, be quiet, walk clockwise around a pagoda, do not photograph monks without asking, and do not point your feet at a Buddha image.

Age shapes address and behaviour, which is why Koreans ask it early; it is not rudeness.

Tipping is not practised and can cause confusion.

Rubbish: bins are scarce in public, and separating waste is a legal requirement in accommodation.

Smoking is banned in most indoor public spaces.

Emergency numbers: 112 for police, 119 for fire and ambulance. The 1330 travel hotline runs 24 hours with English, Chinese and Japanese interpretation and can relay to emergency services.

Medical. General hospitals in Cheonan, Cheonan-Asan and Gongju handle serious cases; larger university hospitals are in Daejeon, close by. Treatment is good and inexpensive, and payment is expected at the time.

Tides: the coastguard publishes tide tables, and warning signs on the flats are not decorative. If cut off, stay where you are and call rather than wading.

Typhoons and heavy rain: alerts are pushed to every mobile phone in the affected area, in Korean, and are worth translating rather than dismissing.

Lost property is very often recovered; report it at the nearest police box.

Embassies are in Seoul, about ninety minutes away.
