The Indiga rises on the northeast edge of the Timan Ridge. It flows in a north-northwesterly direction through the Malozemelskaya Tundra before flowing into Indigskaya Bay, a small bay east of Chosha Bay on the coast of the Barents Sea. At its mouth on the right bank is the settlement Indiga.
The Indiga has a length of 193 km and a watershed of 3790 km². On the upper reaches of the river has rapids. In the lower reaches of the Indiga runs in a wide river valley.
