The second article of Jomblang Cave will explore about the activities that would be available while you are underground.
What to do:
- Exploring the underground forest
After all the struggling process of climbing down the cave, you would be greeted by a scene of underground ancient forest. Research shows that the forest has existed even before the cave was formed by the natural geological process. It is totally distinct to the view on top that is mostly surrounded by withering plants and trees scattered around the karst mountaineous area. Some of the most common plants found would be shrubs and moss that is covering the cave’s wall.
- Mesmerizing at the beauty of Grubug’s cave
Once you pass through the underground ancient forest, you would find yourself walking through an underground tunnel (± 300m) that connects Jomblang Cave to another underground cave known as Grubug. By the time you reach the end of the tunnel, you would be mesmerized by the stunning view known as the ‘Heaven’s Light’. It is a view of the sunlight that goes through the dark Grubug Cave and reflected by the stalactite and stalagmite. What makes it perfect is how the sunlight also glistens the water dripping from the cave’s ceiling. This is the reason why it is best to visit this place when the sun is on its peak as the ‘Heaven’s Light’ is on its maximum beauty during this time.
- Exploring the underground river
In addition to the ancient forest as well as the ‘Heaven’s Light’, you would also discover an underground river that connects Grubug Cave with several other underground caves located at the same Kidul Mount karst mountaineous area. The underground river comes from Kalisuci River located at the northern side of Grubug Cave. The visitors could opt to explore this river by rubber boat. Another available option that would be much more challenging is river tubing. Usually, it would be done in a group, with the local guide leading at the front while pulling a string connected to all the tubes where the visitors are lying on. No matter which option you choose, you would witness another kind of hidden beauty while exploring the river. Along the cave’s wall, you could see the stalactites and stalagmites forming an artistic natural carving that are indescribable with words. However, this activity could only be done during fall season as the current would be too dangerous during the rainy season.
