Pang Sida Butterfly Festival in Mueang Sa Kaeo
The Pang Sida Butterfly Festival centers on guided butterfly observation inside Pang Sida National Park, timed to seasonal blooms that draw large numbers of species to the forest. Along the way, visitors pass mineral-lick gatherings where butterflies cluster on forest paths, and park rangers provide interpretation focused on habitat and keeping a respectful distance from the insects.
Pang Sida National Park turns into an open-air classroom each year when its butterfly population peaks, and the festival built around that peak is less a program of performances than a guided walk through the forest.
