What to Do in Jeju Island in December

This guide is written for first-time international visitors trying to figure out what to do in Jeju Island in December, especially if you have never been to South Korea before.

I get asked the same three questions every winter: is it too cold, is there anything open, and how do I get around without speaking Korean. All three have straightforward answers once you know the island’s winter rhythm.

December on Jeju is quieter than any other month, cheaper on flights and car rentals before the Christmas rush, and still gives you citrus orchards, camellia gardens, and a sunrise hike that does not require a 4am alarm in July heat.

By the end of this guide you will know roughly 3 price ranges, 2 bus numbers, and the exact months a key mountain trail stays open.

Is December Really a Good Time to Visit Jeju Island?

Yes, December works well if you want mild daytime weather, thin crowds, and fresh citrus, as long as you pack layers for coastal wind and possible snow on Hallasan.

Jeju City’s daytime temperatures in December typically sit between 3°C and 11°C, with sources tracking a monthly average near 10.7°C for the island’s lowland areas.

Nights drop closer to freezing, and the coastal wind makes it feel colder than the number on your phone.

Snow on the lowland coast is rare, but Hallasan’s upper slopes are usually already snow-covered from late November, so the same day can feel like two different seasons depending on your elevation.

Location	Typical December range	What to expect
Jeju City / coast	3°C to 11°C	Mild, windy, rarely snows at sea level
Hallasan mid-slopes	-2°C to 5°C	Frost and icy patches on trails
Hallasan summit area	-5°C to 3°C	Snow cover, restricted access in heavy snow

According to the Korea Meteorological Administration, Jeju’s winter climate is milder than most of mainland Korea, which is exactly why so many domestic travelers escape here in December rather than further north.

How Do I Get From Jeju Airport Into Town?

Jeju City is only about 10 to 15 minutes from Jeju International Airport by taxi, and three options cover almost every traveler’s needs.

I always tell first-timers to decide this before landing, because the airport taxi queue on a cold December evening is not where you want to be reading reviews on your phone.

A T-money card, sold at any 7-Eleven near the airport, works on city buses and most taxis, so grab one on arrival even if you plan to rent a car later for day trips.

Option	Time to city	Rough cost	Best for
Taxi	10–15 min to Jeju City	Metered, higher at night	Late arrivals, small groups
Airport limousine bus (600 / 800)	15–60 min depending on stop	Low fare, pay by card or cash	Budget travelers, light luggage
Rental car	30 min including shuttle pickup	Daily rate varies by season	Camellia Hill, farms, Hallasan access

If you are renting a car, bring an International Driving Permit — most counters will not hand over keys without one.

Photograph the car on pickup, and expect the shuttle-and-paperwork process to take about 30 minutes before you actually drive off.

For how winter road rules change once snow hits the mountain roads, the winter driving rules and chain laws on Jeju’s mountain roads are worth skimming before you book.

What Are the Best Things to Do in Jeju Island in December?

The four things worth building a December day around are tangerine picking, Camellia Hill, the Seongsan Ilchulbong sunrise climb, and Hallim Park on a windy day.

Pick Tangerines at a Winter Citrus Farm

December is peak citrus season on Jeju, and u-pick farms scattered across the island let you taste as you go and take a bagful home.

Most tourist-friendly farms sit a short drive from the airport or Jeju City, and entry typically runs in the range of a few thousand won per person with unlimited tasting included — one farm close to the airport charges around 7,000 won per person, though prices and hours vary by farm and season, so confirm before you drive out.

From January, late-season hybrids like hallabong and cheonhyehyang start showing up too.

See the Camellias Bloom at Camellia Hill

Camellia Hill is open through the winter with roughly 500 species of camellia trees in bloom from November into February.

Winter hours generally run from 8:30am to 6:00pm, with the last ticket sold about an hour before closing, since the garden has no outdoor lighting and closes near sunset. Parking is free on-site, which matters if you are driving yourself between stops.

Watch Sunrise From Seongsan Ilchulbong Peak

Seongsan Ilchulbong, Jeju’s UNESCO-listed tuff cone, is open daily except the first Monday of each month, with winter viewing hours generally around 7:30am to 7:00pm and last admission earlier than closing.

Adult admission runs around 5,000 won, with discounts for youth and children, and the climb to the rim takes most visitors 30 to 40 minutes on stairs. Bad weather can close the site without notice, so build in a backup morning if sunrise is the whole point of your trip.

Walk Hallim Park’s Lava Caves and Gardens

Hallim Park pairs nine themed gardens with lava-tube caves, making it one of the better rainy or windy-day options in December.

It is built on what was once barren lava rock, so the contrast between the volcanic cave sections and the cultivated gardens is part of the appeal — plan on roughly an hour or two to see both halves at a relaxed pace.

Spot	Typical hours (Dec)	Rough cost	Time needed
Tangerine farm	Varies by farm	~5,000–10,000 won	30–60 min
Camellia Hill	8:30am–6:00pm	Paid ticket, varies	1–1.5 hr
Seongsan Ilchulbong	~7:30am–7:00pm	~5,000 won adult	1–1.5 hr
Hallim Park	Daytime hours	Paid ticket, varies	1–2 hr

For a sense of how these costs stack up against the rest of the country, a seasonal travel costs across Korea breakdown is a useful second read before you set a budget.

Can You Hike Hallasan Mountain in December?

Yes, but only on the trails the park keeps open, and only with real winter gear once snow settles on the upper slopes.

Hallasan’s summit area often sees its first snow of the season by December, and trail access is managed by the park authority depending on conditions — some trail sections may require microspikes or crampons, and rangers can turn back hikers without proper gear.

Start early, since there are fixed cutoff times for reaching checkpoints, and check current trail status with the Korea National Park Service the morning you plan to climb rather than the night before.

• Check which trail is open — not all routes run in winter
• Bring microspikes or crampons if snow is reported
• Start by early morning to clear checkpoint cutoff times
• Layer up: summit wind chill often feels 5–10°C colder than the coast
• Carry water and snacks — there are no shops past the trailhead

When Should You Book a December Trip to Jeju?

Book at least a few weeks ahead for the week around Christmas and New Year, and travel in early December if you want the lowest prices and the thinnest crowds.

Jeju’s domestic flight seats and rental cars tighten up fast once Korean school winter break and the Christmas-to-New Year stretch begin, and Seongsan Ilchulbong gets noticeably busier for New Year’s sunrise watching.

Early-to-mid December still has full tangerine season, open camellia gardens, and far shorter lines, which is the window I point most first-time visitors toward.

If you are weighing Jeju against a different month entirely, it’s worth comparing against what to do in Jeju in June before locking in dates.

FAQ

Is Jeju Island too cold to visit in December?

No — daytime temperatures usually stay between 3°C and 11°C in Jeju City, which is mild enough for walking and outdoor sightseeing with a warm layer.

Do I need a rental car to see Jeju in December?

Not strictly, but a car makes reaching farms and Camellia Hill far easier since limousine buses cover main routes only and stop running before 10pm.

Is Hallasan open to climb in December?

Yes, on approved trails, but the upper sections can require microspikes or crampons once snow settles, so check the park service’s trail status that same morning.

What should I pack for Jeju Island in December?

Pack a windproof jacket, layers for a 3°C to 11°C range, and sturdy shoes — add winter hiking gear only if Hallasan is on your plan.

So that’s the real shape of a December trip to Jeju: mild coastal days, a genuinely cold mountain summit, citrus everywhere, and far fewer crowds than any other season. If you’ve been to Jeju in a different month, how did the weather and crowds compare to what’s described here?
