The Banteay Srey Butterfly Centre is a worthwhile place to include on a trip to Banteay Srei and the Cambodia Landmine Museum. The largest fully enclosed butterfly centre in southeast Asia, it has more than 30 species of Cambodian butterflies fluttering about. It is a good experience for children, as they can see the whole process from egg to caterpillar to cocoon to butterfly. The centre is trying to provide a sustainable living for the rural poor and most of the butterflies are farmed around Phnom Kulen. It’s located about 7km before Banteay Srei on the left-hand side of the road.
