Ao Talo Wao and Talo Udang (Talo Wao and Talo Udang Bays)
are the two bays which share similar natural and scenic characteristics. In addition to natural attractions
and scenic beauty on the island, visitors to Tarutao are alsoattracted by historical remains as the island
was once used as a maximum security center for first degree criminals and political prisoners, a place
reminiscent of pains and bitterness suffered by the detainees. Traces of the building structures such as a
10-kilometer road linking between two detention centers (one at Ao Talo Wao and the other at Ao Talo Udang)
can still be seen. There are also ruins of housing for prison staff, a concrete tank for storing fish, tombs,
brick furnaces for producing charcoal, and other utensils. Ao Talo Udang is unique in that it is located on
the lowest point of the island, with a long history, and the existence of a cave with much sought-after edigle
swallow's nests.
