Jeju Volcanic Island and Lava Tubes

The Ultimate Guide to Jeju Volcanic Island and Lava Tubes

Introduction

Jeju Volcanic Island, located off the southern coast of South Korea, is a UNESCO World Heritage Site and one of the most popular tourist destinations in Asia. The island is home to numerous natural wonders, including stunning beaches, lush forests, and majestic volcanoes. One of the most fascinating attractions on Jeju Island is its extensive network of lava tubes, which offer a unique glimpse into the geological history of the region.

Geological Background

Jeju Volcanic Island was formed approximately 2 million years ago as a result of intense volcanic activity. The island is home to over 360 parasitic volcanoes, including Hallasan Mountain, the highest peak on the island and a dormant volcano. Over time, lava flows from these volcanoes created a vast network of tubes and caves, which have been preserved and protected for millions of years.

Lava Tubes: A Natural Wonder

The lava tubes on Jeju Island are a testament to the region’s volcanic past. These natural wonders were formed when lava flows cooled and solidified on the surface, while still molten beneath. As the lava continued to flow, it created a hollow tube-like structure that remained intact even after the volcano became dormant.

Manjanggul Lava Tube

One of the most famous and accessible lava tubes on Jeju Island is Manjanggul Lava Tube. Located in Gujwa-eup, this 9km-long tube is considered one of the world’s longest and most well-preserved lava tubes. The tube is divided into three sections: the Entrance Zone, the Main Zone, and the Exit Zone.

  • Entrance Zone: This section features a large entrance hall with a high ceiling, as well as several smaller rooms and passageways.
  • Main Zone: This section is characterized by its vast, tunnel-like structure, which stretches for over 4km. The walls and ceiling of the tube are adorned with stunning formations, including lava stalactites and stalagmites.
  • Exit Zone: This section features a narrow, winding passage that leads to the exit.

While Manjanggul is the most famous, there are several other lava tubes on Jeju Island worth exploring:

  • Bunjae Lava Tube: Located in Seogwipo-si, this 2.5km-long tube features a unique “lava waterfall” formation.
