The staff were very friendly and there were many of them, and you could ask for help taking photos, and they were also informative. I went there alone, but thankfully I met some nice people who were willing to go with me. Unfortunately, I arrived quite late in the afternoon, so I couldn't stay long at Galnas, and I had to rush the time. It was quite crowded when I arrived, so if I wanted to take photos, I had to take turns. If I go to Jakarta again, I'll definitely stop by Galnas again.
