Mu Ko Surin Island National Park , for many years Mu Ko Surin was an unspoiled group of islands, acting as a refuge for fishing boats during storms and hosting small communities of sea gypsies. In this situation the islands provoked little interest and for a long time were recorded as a National Forest Reserve by the Royal Forest Department, But on 30th December 1971 the National Committee on Wild Animal Reservation and Protection suggested that the islands should become a wildlife sanctuary. An alternative plan then proposed to develop the islands as a Vietnamese refugee camp. This idea was rejected as it was realized that the trans location and support of so many people in such a fragile enviroment, would soon result in damage to the islands pristine land and marine habitats.
