The Dobra River, which feeds the pool, eventually flows into the Sella River, famous for the International Sella Descent.

The Senda de la Olla de San Vicente is a popular hiking trail in Asturias, Spain, known for a distinctive turquoise-colored natural pool formed by the Dobra River. The trail leads visitors through a canyon landscape featuring limestone rock formations and indigenous vegetation. The primary destination is a deep, cold basin carved into the riverbed by erosion. It is part of the Picos de Europa region, situated near the transition from the mountains to lower altitude areas. The route is approximately 2.5 kilometers long one way, involving a moderate walk through a forest path. The river water remains exceptionally cold even during high summer temperatures. The area is prone to high visitor density during weekends and peak summer months. It is located near the boundary of the Picos de Europa National Park.
