Vida silvestre en ríos y humedales
Las riberas, los bosques aluviales y los tranquilos canales secundarios ofrecen hábitats muy distintos a los de las aguas abiertas. Las aves pueden verse desde la cubierta, mientras que los mamíferos más esquivos suelen requerir un guía local y una excursión en tierra adecuada.
Elige el tramo del río adecuado
Una especie que habite en una cuenca fluvial puede vivir lejos de tu ruta de navegación. Las excursiones al delta del Danubio, los acantilados del Duero Internacional, las pozas de delfines del norte de Camboya y los humedales de Tonlé Sap son experiencias distintas. Confirma la excursión real y las condiciones de acceso antes de reservar.
Observación responsable
Mantén una distancia respetuosa, evita alimentar o molestar a los animales y sigue las normas de los guías locales y de las áreas protegidas. El clima, los niveles de agua y el movimiento de la fauna afectan a cada salida.
