Koh Kradat is a low-lying island northeast of Koh Mak, with shallow waters that offer plenty of fun for kids. You can also join a deer spotting tour; around 2,000 wild deer live on this privately owned island. It will be an excellent experience for a wildlife photographer. The deer are friendly so you can feed or watch them go about their way. Koh Kradat Island has a few locals who run a resort and a small restaurant. There is an entry fee for the tourists to step on this private island, which includes deer spotting on a tractor.
