Bird Park in Tam Coc - many butterflies but no birds

The park itself is big and nice, there are boat tours available. Apparently, we have not seen any birds there, but we enjoyed walking in this park, and there were so many butterflies. One more highlight is the mermaid cave, but be careful as the ceiling is very low. You have to go in a kneeling position there. It's nice and cool inside. Also there are many scenic photo spots. #vietnam #ninhbinh
