During the evening we booked ourselves to go on a firefly tour. This cost only 60 Baht per person and they came and picked us up at our homestay. The first few groups that we passed seemed more like cheap Christmas trees flashing in synch. To be honest, I thought that they were fake lights. However, later on we were able to get close to some trees where we could actually see them flying around. They are not easy to photograph but I did manage to get this one.
