Quebrada Infiernillo is an intermittent stream approximately 15 kilometers long located in the Coquimbo Region of Chile, flowing through the Elqui Province near the town of Vicuña. Its character as an intermittent watercourse means its flow is not constant and can be highly variable, dependent on seasonal rainfall. This is highlighted by reports of its activation, indicating it can become a significant flow channel during or after precipitation events, particularly in the comuna of Los Vilos. For paddlers, this signifies a waterway that may only be navigable during specific, often unpredictable, windows following rain, requiring careful planning and verification of current water levels.

Dedicated paddling and fishing websites indicate the water body is used for recreational activities, though no specific details on the exact location of access points, the nature of the facilities, or recommended routes are provided. Similarly, while the existence of regulations is noted, their specific content pertaining to paddling on Quebrada Infiernillo is not detailed. The intermittent nature of the stream is the primary and critical safety consideration, as water levels can change rapidly. Paddlers must prioritize checking local conditions and heeding any activation alerts before attempting a trip.
