From San Jose by car it take about 2 in a half hours to get there.
It is best to photograph in the morning because it often rains in the afternoon.
I shot this picture on a three hour path through the jungle. The butterfly was perched on a tree and it did not move for about five minutes, plenty of time for me to take the shot. It was handheld and I used my telephoto lens in order not to scare her. The focal length was 146 mm, at F/5 and the exposure time was 60 sec. but there is no movement in the picture because I used a flash. It was shot July 7, 2011.
