I went there with only one bird in mind and that was the Rail-Babbler.
I stayed about 6 days and it turned into a very enjoyable hop. There is a nice stream running threw the main camp site. I set my tent next to the stream and really hated to leave.
Krung Ching is not a hot spot for birding, but that will change pretty fast I have a feeling. I feel lucky to be able to explore it while it is still fairly quiet. Mostly Thai family's and a few farang ( tourists ). Most tourists when I was there did not stay long.
There are no Guest houses close by that I found and the nearest town was about 20-30 Km. away. So the park is fairly isolated.
Also the treck to the waterfall requires a fairly strenuous climb up the side of a small mountain. Not really a bad climb, but I would suggest you start slow and take your time. Then it is a piece of cake.
Birding? I found it to be a very good birding park. If you take your time and stay for a few days it really starts to grow on you. It is teaming with birds from the south of Thailand. The forest is extremely dense, birding as far as photography is rather difficult. But if you find a good fruiting tree you can have a great time.
It took me 4 days of trekking up the mountain, locating it, and luring it in to photograph it. I packed a backpack with my 300mm lens and portable blind, each day and hiked up the mountain.
While in the park I was lucky to find a fruiting tree and got a few other bird while there. Here are a few.
This park is a very good park that I intend to explore at my leasure. Many more times to be sure. It is teaming with birds and a great place to explore. With out the usual pressures of the big parks. I enjoyed it.
There is no restaurant at the park. There is a small store that sells chips cold water and general supply's. So bring your own food and supply's. There is a bungalow there and can be had for 300 Baht per person. Fan only pretty bare accommodations.
As usual birding is free.... you do not have to spend big bucks period. Get out and enjoy it.
