Ngarchelong is the name of an administrative division of the country of Palau. Ngarchelong is at the northern most tip of the island of Babeldaob. It is an important historical site and has undergone archeological excavation.

Ngarchelong is the site of ancient stone monoliths which are mysterious in origin. Traditional Palaun religion regarded these stone monoliths as sacred prayer ground. There are other stone monoliths located in and around the islands but one will not see as many as there are in Ngarchelong.

To get there, one has to take a tour bus or rent a jeep and ride a dirt road for about three hours.
