Where are Cuc Phuong butterflies most concentrated?
Butterflies are mostly concentrated along the banks of Mac Lake, at the entrance to the Ancient People Cave, in the core area of Bong, and on the way into the forest (especially in places that are damp with standing water and plenty of sunlight).
The ideal time to "hunt butterflies" is in the morning from 9 AM to 2 PM, when the sun is shining.
Wearing light-colored clothing, especially white, is also said to attract butterflies more easily. Additionally, a small tip is to bring a little sweet water or salt water, pour it on the ground to gather more butterflies, making observation and photography easier.
