Generally, caves in Indonesia consist of limestone and exist on hillsides. Thus, stalactites and stalagmites are often formed. However, there is one cave in Purbalingga, Central Java, namely Gua Lawa, which is a volcanic one formed from active mountain lava that has melted and cooled from thousands to millions of years. This lava cooling process causes the rock to be hard and strong with a black color without causing stalactites or stalagmites. The thickness of the rock can reach 50 meters. So, it is resistant to shocks. Lawa Cave is located at the foot of Mount Slamet, precisely in Siwarak Village, Karangreja District, Purbalingga. This place is called Lawa Cave because there are many bat animals in it. Lawa Cave or also commonly called Golaga by the local people, has a length of about 1.5 km with an altitude of about 900 meters above sea level so that the air feels cool.
In addition to the natural beauty of Lawa cave, visitors may also enjoy this more attractive tourism destination, which has been carried out by the Government of Purbalingga Regency. Since operating the day after Eid al-Fitr in 2018, this tourism destination provides a unique coffee shop located in a cave. With the advent of these facilities, the number of tourists visiting has increased drastically. This facility is certainly appropriate for tourists who want to rest for a while after going around the cave. Sipping a cup of warm coffee is enjoyful to see the exotic scenery of the cave decorated with colorful lights, such as red, blue, green, and others that alternately turn on to be an unforgettable experience.
