Manjanggul Caves and Samyang Beach

Referred to the local buses, which we are due to the lack of an international driver's license, we took the bus to the underground channels that the lava once flowed through - Manjanggul. The buses run frequently, so it is fortunately easy and very green to use public transport. South Korea is very keen on "being green". Think about the environment and eat organic. The bus dropped us off on the side of the road with a Japanese man who was going the same way, so we shared a taxi the last part of the way. He had once had a Danish girlfriend, so he had visited Denmark - in fact, he was quite well-traveled. He had 140 countries on his business card. Entrance to Manjanggul is only 2,000 won per person. There are 13.4 km of underground lava channels located, of which 1 km is safe enough to be explored by tourists. Here you can see how the lava has fought its way underground and made deep wear marks. In some places, the lava pressed up against the surface of the earth if the space became too tight. This resulted in dome-like ceilings. If the lava got too close to the surface, a hole would burst, allowing the lava to flow freely. At the end of the 1 km long tunnel there is a column where the lava has dripped down from the ceiling. This lava column is the highest in the world. It is an easy hike underground, you just need to remember practical shoes and clothes, as water drips down from the ceiling, and the temperature is cool down in the corridors. It takes about 40 minutes to hike there and back. It is very exciting and a little scary to walk underground and think that burning hot lava has gushed through these channels. We jumped on the bus back towards Jeju-Si, where we stopped at Samyang Beach, whose characteristic is its black sand, which is said to have healing powers - among other things, it should relieve neuralgia. So people bury each other in the sand and lie down and wait for a helping hand :o)
