Thanks. There are more photos in my albums. Check them out

The cave with bats is Jlamprong Cave in Semanu, Gunungkidul. To take photos with bats we need to go in at dusk where bats are become active.
You might want to visit Cerme Cave in Imogiri, and Seplawan Cave in Kulon Progo. Trust me, they are interesting.
Please check-out my albums, there you could see several caves and other outdoor activities
