This butterfly pavilion is home to between 1 000 and 1 300 specimens belonging to over 50 local species, best viewed in July and August and October and November. To admire the largest number of species, a visit on a warm, sunny day is recommended. The area around the pavilion, along a small river created from the Kuang Si waterfalls, has been transformed into a botanical garden featuring species from around the country, including orchids, bamboo, ferns and cacti. A natural swimming pool is located at the entrance.
