Bolshoy Nimnyr is a river of 204 km length, right tributary of Aldan.
Bolshoy Nimnyr's coast is covered a set of huge stone. In the narrow gorge where the river rushes, these stones heat up a way to water, creating the dangerous thresholds, which are ending, as usual, with "barrels". The most dangerous thresholds have names, for example: Nimnyrsky, "Nikolkin Klyuch" "Passed" and "2nd Ulovo"
