The breathing sound is the sound that female divers make when they come up to the surface after diving and clear their throats, and it sounds like a whistle. It is the sound of "hooi hooi" that is made when they breathe out all the carbon dioxide that has been accumulated in their bodies while diving for about 1 to 2 minutes and inhale oxygen. Through the "sseobiseori", female divers can quickly take in fresh air into their bodies and continue diving even after a short break.

If there are 13 or more tour guests, an English tour guide will accompany the tour.

Currently, Manjanggul Cave is temporarily closed and is scheduled to reopen after April 2026. Manjanggul Cave information Manjanggul lava tube information Manjanggul Cave is a natural cave formed approximately 100,000 to 300,000 years ago by lava flowing from Geomun Oreum, one of the small mountains in Jeju, along the surface. It is the core of the Geomun Oreum Lava Cave System, which was designated as a UNESCO World Natural Heritage Site in 2007. The general exploration section extends about 1 km inward from the Second Entrance. The main passage, measuring 18 meters in width and 23 meters in height, evokes a sense of openness that makes one forget it is an underground space. At the end of the section stands a 7.6-meter-tall lava column, the symbol of this cave. Formed by the lava flowing from the ceiling and solidified lava on the floor coming into contact to form a single column, it is the largest lava column known to date in the world. Manjanggul Lava Cave is approximately 7.4 km long and features a multi-layered structure in some parts. The main tunnel measures 18 meters in width and 23 meters in height, making it one of the largest lava caves in the world. Due to a collapse of the cave ceiling, the entrance is divided into three sections; However, tourists are only allowed to use the second entrance, and entry is permitted only up to a maximum of 1 kilometer. Inside Manjanggul Lava Cave, visitors can observe various cave formations, including stalactites, stalagmites, flowstones, lava flows, lava shelves, and lava rafts. In particular, the lava column located at the edge of the tourist area reaches a height of approximately 7.6 meters and is known as the tallest lava column in the world. When descending the stairs in Manjanggul, you must proceed very carefully, step-by-step, while keeping an eye on your footing. Since the interior is kept dark to preserve its natural state as much as possible, you must always walk cautiously during the cave tour. Additionally, you must be careful as there are small puddles of water at intervals along the 1-kilometer flat path. Water may also drip from the ceiling during heavy rains. Regardless of the temperature above ground, the interior of Manjanggul Lava Cave maintains a temperature of 10–15°C year-round, remaining in its natural state for a long time, unaffected by seasonal changes. It is very cool in the summer, but becomes very cold from autumn onwards, so a winter jacket is essential.

On these tours, a driver is always assigned to accompany the customer, walking with them and taking photos for them. (Excluding hiking courses)
