Arribes del Duero environmental cruise
The International Biology Station’s classroom-boat sails along the most spectacular stretch of the Arribes del Duero/Douro Internacional border park, providing a fascinating insight into the fauna, flora, geology, ethnographic resources and the breathtaking sheer cliffs, offering a choice of activities ranging from 1 to 3 hours’ duration.
The boat, which can carry up to 120 passengers, is soundproofed and blends into its setting. It features an air-conditioned glass deck, outdoor terraces with space for all passengers, a laboratory, an exterior microphone for wildlife and infrared night vision cameras for research purposes.
