The descent from the other side of the dam should be considered OFF-ROAD as it is falling apart… The view of the dam from this side is great…

The landscape is part of the Ria Farmosa. The Chameleon Trail also leads right past this charming little village. So always be careful 🤗

Parque Natural da Ria Farmosa You can walk for miles along the beach from Tavira to Fábricia. From there you can take a small boat to the town for €1.50. The beach is almost deserted for early June. Small and large shells line the path, in my opinion one of the most beautiful beaches in Europe.

In 1984, an artificial island was constructed in the swamp area, partly to improve bird life. More than 6,000 flamingos now reside in the Odiel marshes, making it the second largest colony in Spain.

Beautiful panorama of the marsh where hundreds of birds look for the fishes. Be careful - part of the path is on closed areas of golf club.

Pretty little beach in the Ria Formosa National Park. The special thing is that it is located on an island and can only be reached by swimming (from Praia Manta Rota) or by a short boat trip (from Sítio da Fábrica). Due to its location, it not only has the Atlantic Ocean, but also a lagoon.

The Odiel marshes are a Unesco biosphere reserve and a natural area located at the mouth of the Odiel river. These wetlands originated from the sedimentary processes coming from the mouth of the Tinto and Odiel rivers together with the dynamics of contributions from the Atlantic Ocean, which gradually formed a large estuary, making the area one of the most important tidal areas in Andalusia. .
