It is a bit of a miracle that this pristine slice of dense jungle is not more visited, considering it is only a few hours drive north of Phuket. All the big game are advertised to roam the national park, but the chance to see a tiger, leopard or sun bear is probably pretty slim. A wild elephant on the other hand is not impossible. The park's pride-worthy botanic attraction is the world biggest flower, Rafflesia (Rafflesi kerrii). This giant flower (50-90 cm) is both rare and weird (smells of rotten meat) and blooms only in dry season from January to March. There are several trails throughout the park to waterfalls and viewpoints. You cannot sleep inside the park, but the guest houses right outside are famous for their treetop bungalows.
