THE LANDMARK

Ponte do Freixo

The outing begins at the Marina do Freixo beneath the Ponte do Freixo, setting the scene for the riverine route that follows downstream and then upriver toward the Crestuma‑Levern dam.

THE ENGINEERING

Barragem de Crestuma‑Levern and its Lock

A defining moment on the route is the passage through the Crestuma‑Levern dam and its eclusa (lock), a mechanical transition that the boat navigates as it moves upriver and again on the return downstream.

THE WATER

Rio Inha — Swimming and Snack Stop

The itinerary features a lengthy 120‑minute stop at the Rio Inha for bathing and a light lunch or snack, providing the primary on‑water pause of the trip.
