Tongo is a town in north eastern Ghana, in the region of Bolgatanga. It is known for the Tengzug shrine and for its sowing and harvest festivals. Another visitor's sight in the region is the Tongo Whistling Rocks. Located 6 miles (10 km.) from Bolgatanga, these granite rocks jut dramatically from the terrain. The rocks also make a strange whistling sound during November and December, when the harmattan wind blows from the Sahara throughout the Northern Region.
