Things to Do in Jeju in March

March is the start of spring on Jeju, and it's one of the most rewarding times to visit. Temperatures range from around 7°C (45°F) in early March to 14°C (57°F) by month's end, with mild days but cool, often breezy evenings. The island's famous canola flowers (유채꽃) begin their golden bloom across the countryside — particularly around Jeonnongno and the fields near Seongsan Ilchulbong — drawing photographers and nature lovers before the summer crowds arrive. It's a sweet spot between winter quiet and the late-March spring rush.

March is prime time for chasing Jeju's canola flower season — cycling or driving through the fields around Seongsan, Gimnyeong, and Pyoseon is unforgettable, and Jeonnongno in Jeju City becomes one of the island's most photographed corridors. Hiking Hallasan is excellent before summer heat and humidity set in, with clear skies and far fewer trail crowds than April. The coastal Olle Trail routes are at their most pleasant, and late March often brings the first cherry blossoms to Jeju City's streets. For rainy days, Spirited Garden, Jeju Folk Village, and the island's thriving café scene are all worth your time.

Early March on Jeju can feel like a lingering winter — expect temperatures around 7–9°C (45–48°F), occasional rain, and blustery coastal winds that make it feel colder than the thermometer suggests. The canola fields haven't peaked yet, though you may spot the first yellow blooms appearing in sheltered southern areas near Sanbang-san and Jungmun. It's the quietest and most affordable window of the spring season, with good value on accommodation and thin crowds at popular sites — pack layers and a waterproof jacket.

By mid-March, Jeju starts to feel genuinely spring-like, with temperatures climbing to 10–13°C (50–55°F) and canola flowers spreading more widely across the island's farmland and roadsides. This is a strong window to visit — you get noticeable spring scenery before the late-March surge in domestic Korean tourism pushes accommodation prices and trail crowds higher. Jeju averages around five to seven rainy days in March, so days are often clear and bright between showers, making outdoor walks and coastal drives very enjoyable.

Late March is peak spring season on Jeju. Canola flowers are in full bloom across the island, and the first cherry blossoms typically appear along Jeju City's streets — including the famous Jeonnongno corridor — and at Hallasan's lower slopes. Temperatures reach 13–16°C (55–61°F), making hiking and outdoor exploration very comfortable. This is also when domestic Korean tourism picks up sharply, so book accommodation and popular restaurants at least two to three weeks ahead, especially for weekends and any Korean public holiday periods.

Jeju has two distinct peak seasons: summer (July–August), when Korean families flock to its beaches and water parks, and spring (late March–April), driven by the canola flower and cherry blossom season. A secondary autumn peak in October draws visitors for Hallasan's foliage. Winter (December–February) is the quietest and most affordable period, though Hallasan can see significant snowfall and some coastal attractions have reduced hours.

Jeonnongno is a tree-lined avenue in central Jeju City that transforms in late March into one of the island's most iconic springtime scenes — a simultaneous bloom of cherry blossoms overhead and canola flowers along its borders. The annual Jeju Cherry Blossom Festival is held along this street, typically in late March to early April, with food stalls, live performances, and large crowds of local visitors. It's walkable from central Jeju City, free to enjoy, and best visited on weekday mornings to avoid weekend congestion.

The Jeju Canola Flower Festival (제주 유채꽃 축제) is typically held in late March to early April, timed to coincide with peak bloom across the island. Main festival activity tends to centre around Jeonnongno in Jeju City and the photogenic fields near Seongsan Ilchulbong on the east coast. Exact dates shift slightly each year depending on flowering conditions and weather, so check the official Jeju Tourism Organization website (visitjeju.net) closer to your travel dates for confirmed programming and event locations.

May is warmer (18–22°C / 64–72°F), greener, and more settled weather-wise than March, but the dramatic canola and cherry blossom displays are over. Hiking on Hallasan is excellent in May with lush vegetation and stable conditions, and the coastal Olle Trails are at their most inviting — though the sea is still too cool for most swimmers. May also precedes the summer monsoon rains, making it reliably pleasant. If spring flowers are your primary reason to visit, March wins decisively; if you want warmth and outdoor activity without summer-level crowds, May is the better choice.

For early and mid-March, booking one to two weeks ahead is typically sufficient, as the island remains relatively quiet. Late March is a different story — the convergence of canola flowers, cherry blossoms, and spring school holidays triggers a sharp increase in domestic Korean tourism, and well-located guesthouses, pensions, and hotels around Seongsan and Jeju City can sell out three to four weeks in advance on weekends. If your dates overlap with a Korean public holiday, book as early as possible and have a backup property in mind.

March is one of the better months to hike Hallasan — summer heat and humidity haven't arrived, and most trails clear of snow by mid-month, though early March can still leave icy patches on the longer Gwaneumsa and Seongpanak routes where microspikes or crampons may be advisable. The shorter Eorimok and Yeongsil trails offer rewarding alternatives with early spring vegetation and manageable conditions for most hikers. Always check the Korea National Park Service website (knps.or.kr) before heading out, as trail closures are enforced regularly and without much notice.

Jeju in March demands a layering strategy: a warm mid-layer such as a fleece or light down jacket, a waterproof and windproof outer shell, and sturdy walking shoes that can handle wet, muddy paths on the Olle Trail and Hallasan. Coastal wind chill around Seongsan Ilchulbong and the northern shores can make temperatures feel several degrees colder than they are. Evenings cool down noticeably even on warm days, so always carry an extra layer. From mid-March onward, add sunscreen — spring UV levels on the island catch many visitors off guard.
