Sterna - Aveiro Ria Tours & Birdwatching

Sterna runs silent boat trips on the Ria de Aveiro, in a boat powered solely by solar energy and producing no emissions. It's a nature and nautical tourism company based in Aveiro, and it sets out to show visitors the natural beauty and rich biodiversity of the lagoon. The Ria is a sensitive estuary, and Sterna operates across more than 200 km of its navigable waterways. There are several trips to choose from. The “Duas Águas” tour follows some of the Ria's main channels. The more immersive “Esteiros” trip goes into wilder, less-travelled parts of the lagoon. Sterna also organises dedicated birdwatching programmes. The Ria de Aveiro is one of the most important wetlands on Portugal's northern coast, with a great variety and abundance of wild birds. Special programmes are available for celebrations, sunset tours and other bespoke occasions. The company works from the idea that “silence is the new luxury”. The trips put the emphasis on calm and sustainability, and a knowledgeable, relaxed team looks after visitors. Sterna is committed to protecting the delicate estuary formed by the delta of the River Vouga, and to promoting responsible, low-impact ways for visitors to connect with nature. Sterna operates under the registered brand of Popular Flamingo Unipessoal, Lda., and is licensed as a nature tourism operator (RNAAT 214/2020).
