Small insects and spiders on forest leafs of Cuc Phuong National Park

Cuc Phuong is a National Park of North Vietnam, it is one of the most early national parks of the country. It is a low elevation forest and surrounded by limestone range.

It is not very far from Hanoi (about 120km) to the South and the forest in a very good condition. The national park located at border of Thanh Hoa and Ninh Binh Province. There is a tourist system in side of the National Park that you can stay over night, the road system in good condition so you can walk, ride bicycle, motor cycle or drive a car go through the Park without problem. On two sides of the main road, and in a summer days, there are a lot of insects that you can observe or taking photograph. The fauna of Cuc Phuong maybe similar to Ba Vi National Park however because it is a low land forest so it some how difference.

Insect/Spider watching is one of the most interesting thing in Cuc Phuong, however watching of birds, snails or amphibians... also is not bad option.
