Kalós Potamós is located in northeastern Crete, in the Lasithi region, in the area of Istron (Kalo Chorio), east of Agios Nikolaos.

It is a small seasonal river that flows through a low-lying valley and reaches the sea near the local beaches, including Agios Panteleimonas.

The river’s flow depends largely on rainfall. During the winter months and after periods of heavy rain, water gathers in its riverbed and moves toward the coast, while in summer the flow is significantly reduced or disappears altogether. This pattern is typical of many watercourses in eastern Crete.

Despite its small size, Kalós Potamós shapes a gentle natural landscape along its course, with patches of reeds and low riverside vegetation. The presence of water, even on a seasonal basis, creates a slightly more fertile zone compared to the surrounding dry terrain.

The river follows a natural route through agricultural land and low hills before reaching the sea, where it forms a modest outflow point. This feature adds diversity to the coastal landscape and subtly differentiates the nearby beaches.

Kalós Potamós is a representative example of the small, local rivers of Crete, which, although not permanently flowing, play an important role in shaping the island’s natural environment and landscape.
