About this water

The Ésera drains high granite peaks and flows through a spectacular limestone gorge — two distinct characters creating diverse fishing habitat. Upper granite reaches are cold, freestone with strong wild-trout populations; the Ventamillo gorge section combines limestone clarity with dramatic alpine scenery. Technical water throughout. The transition between geology creates excellent holding habitat.
