The Tarija River is well known for the enormous mountain dorado that inhabit it. It is a fast-flowing and transparent river, with a lot of slopes and strong currents. The dorado there have very large fins and strong musculature, clearly adapted to a river with such high flow. In the last 30 years, despite the river's remoteness, there have been several unauthorized entries of fly fishermen, which testify to the size and power of the dorado in Tarija. That’s why we thought of a floating modality, allowing us to access all sections of the river, including canyons and rapids that are impossible to traverse on foot. The project combines the best of both modalities: floating to reach all corners of the river and the helicopter to enter and exit daily to the lodge to recharge.
