Sangumburi Crater, Jeju Island, South Korea, Asia

Sangumburi Crater is a volcanic cone located in the eastern part of Jeju Island, South Korea. It is a natural monument designated for its unique geological features.

Visual Characteristics

The crater is a large, circular depression with a diameter of approximately 650 meters and a depth of about 100 meters. The inner walls are steep and covered in dense, green vegetation, primarily silver grass (Miscanthus sinensis) which turns golden in autumn. The crater floor is relatively flat and also vegetated.

Location & Access Logistics

Sangumburi Crater is situated approximately 10 kilometers east of Jeju City. Access is via National Road 97 (97번 국도) and then local roads. Parking is available on-site. Public transport options include local bus routes that stop near the entrance; specific route numbers vary and should be confirmed locally.

Historical & Ecological Origin

Sangumburi is a parasitic cone formed by a phreatomagmatic eruption, meaning it was created by the interaction of magma and groundwater. It is one of the few remaining intact volcanic craters on Jeju Island, preserving its original form. The crater is classified as a tuff ring.

Key Highlights & Activities

Visitors can walk along the rim of the crater via a designated path. A wooden observation deck provides panoramic views into the crater. Photography is a primary activity, especially during the autumn when the silver grass is in bloom. Educational exhibits about the crater's formation are also present.

Infrastructure & Amenities

Restrooms are available at the entrance. Limited shaded areas are present along the walking paths. Cell phone signal (4G/5G) is generally available. Food vendors are typically located near the parking area and entrance.

Best Time to Visit

For photography, early morning or late afternoon light offers optimal illumination of the crater's interior. The best months for visiting are September through November when the silver grass is golden and provides a distinct visual contrast. Spring (April-May) offers lush green vegetation.

Facts & Legends

A local legend states that a mythical serpent resided within the crater. Geologically, Sangumburi is notable for its well-preserved, undisturbed structure, offering a clear example of a volcanic tuff ring formation.
