Our last patch of lowland forest, Sri Phang Nga National Park spans 246 square kilometres along a range of hills parallel to the Andaman Sea coast. It is just part of a larger forest which is big enough to sustain Great Hornbill, White-handed Gibbon and Dusky Langur. The forest is on a grand scale but access is limited , it is worth an extended visit but be prepared to cover the same ground repeatedly, although the nature of tropical birding is such that your encounters will be varied because of the high diversity of species and low density of most individuals.
Let me whet your appetite …
Streams in the park hold a diverse range of fish, tossing in a little food can bring a spectacular response.

Sri Phang Nga National Park one of my favourite parks to visit when I lived in the South of Thailand and I spent many hours wandering the paths and wading through the streams there but I was never lucky enough to spot the Banded Pitta, I’m ver jealous.
