While the front part of the cave is very wet, the back part of the cave is relatively dry. Of course, to reach this back part you have to go through a low crawl that can only be navigated on hands and knees or a very hunched crab-like shuffle. Notice that Hyunjin is wearing a hardhat here. Gosu Cave is much larger and has no small space that are open to the public, but Ondal Cave has some tighter spaces.
None of the other people who were in the cave with us elected to go into the back. Some of them gave up before even reaching the crawl, thinking the cave ended, while others turned back upon seeing the crawl. Obviously we weren’t going to be daunted by a little crawl. In fact, it was fun. It felt for a moment like we were real cavers. Well, except for the metal walkway and railings.
The greenish tint on the rocks in the lower right, by the way, is moss and lichen, which grows thanks to the dampness and constant light source.
