Kaeng Krachan national park is a great place for birdwatching with regular sightings of many species of woodpeckers, broadbills and other exciting birds. It also happens to be a superb place for seeing butterflies with huge clouds of them coming to wet patches to take salt in the middle of the day. If one stands close to these clouds of butterflies eventually they will begin to settle on your arm, attracted by the sweat.
For photographers there are some good opportunites for great pictures and even with just a compact camera and a little patience it is possible to get some nice photos. I took these butterfly pictures close to Ban Krang campsite on 21st March 2008 whilst on a birding trip with Alex Vargas.
