About 200km south by plane is Tomtor, the northern Pole of Cold. There is a decaying dirt track around 50km south to one of the few gulags still visible in the region. The good artefacts are in a museum and all the buildings collapsed.
About 100km to the north is the Indigirka gorge, a rather spectacular set of rapids that can be visited by helicopter. Some rafting expeditions have been organised, but not in recent years. The rapids are big enough that fish cannot cross - there are different species above and below.
