Sanbangsan Mountain

Rising like a bell from the flat fields of southwest Jeju, Sanbangsan is a 395 m mountain made of a single mass of lava. It is counted among Jeju's three great mountains alongside Hallasan and Seongsan Ilchulbong, and a Buddha is enshrined in Sanbanggul, a rock cave halfway up. Paired with the Yongmeori Coast just below, it gives you a quick lesson in Jeju's volcanic landscape.

How it formed

Sanbangsan is a lava dome: thick trachyte lava that could not flow far piled up and hardened into a bell shape. Dating puts it at around 700,000 to 800,000 years old, which makes it one of the older landforms on Jeju. "Sanbang" means "mountain with a cave", after the sea cave about 150 m up on its southern face. The mountain was designated a Scenic Site in 2011, and the plants clinging to its sheer cliffs are separately protected as the Sanbangsan Rock Plant Zone, a Natural Monument. Locals long treated it as a weather sign: when clouds wrap around the mountain, rain is said to follow.

Legend: the summit of Hallasan flew here

A Jeju legend says Sanbangsan was once the top of Hallasan. When a hunter's arrow grazed the side of the Jade Emperor in heaven, the furious emperor pulled off the peak of Hallasan and threw it away. The hole it left became Baengnokdam, the summit crater, and the flying peak became Sanbangsan. In reality the two formed at different times and in different ways, but Sanbangsan's circumference is similar to Baengnokdam's and both are made of trachyte, which makes the story hard to resist. Another legend says the drops falling from the cave ceiling are the tears of Sanbangdeok, the goddess who guards the mountain.

What to see

• Sanbanggulsa Grotto: Climb the steps halfway up to find a Buddha enshrined in a deep cave in the rock face. It is said to have been a place of practice since the Goryeo period, and the present stone Buddha has been here since 1985. The view from the cave down to the Yongmeori Coast and out to sea is the highlight.
• Yongmeori Coast: Just south of the mountain, layers of volcanic ash have been carved by waves into unusual cliffs. Nearby is a memorial to Hendrick Hamel, the Dutch sailor shipwrecked on Jeju.
• Sanbang Yeondae: A Joseon-era beacon platform on the coastal hill, a good spot for photos with the mountain behind.
• Canola fields: In spring the fields at the foot of the mountain turn yellow with canola flowers.

Tripto tips

• No summit access: Most of the mountain is a restricted area to protect it as natural heritage. Visitors can only climb as far as Sanbanggulsa.
• Fees and hours: Sanbanggulsa is open 09:00–18:00 (last tickets 17:20) and charges a small fee for adults. A combined ticket with the Yongmeori Coast is available. Prices can change, so check on site.
• Effort: It is a fair climb up the steps to the cave. Allow about two hours for the grotto and the Yongmeori Coast together.
• Watch out: The Yongmeori Coast closes on some days depending on tides and waves. Check whether it is open that day before you go.
• When to go: It is busiest in spring when the canola is in bloom. The sea views are lovely towards sunset.
• Parking: The public car park is free, while private car parks nearby charge a fee.
