Vila Real de Santo António is located on the Gulf of Cádiz, which is part of the Atlantic Ocean, and on the right bank of the Guadiana River, whose lower reaches form the border between Portugal and Spain. The town boasts several attractions, charming restaurants, bars, and cafés! And of course, a lighthouse! 👀 A ferry ⛴️ runs hourly to the Spanish town of Ayamonte. ...

The Vila Real de Santo António Lighthouse (Farol de Vila Real de Santo António) is located in the far east of the Algarve, near the Spanish border. Built in 1923, it stands 40 meters tall. Situated on the dunes near Praia de Santo António beach, the lighthouse guides ships approaching the mouth of the Guadiana River. It is a striking landmark in a flat coastal landscape and is sometimes open to the public on special days.

At the mouth of the Guadiana River lies the Castro Marim and Vila Real de Santo António Marshland Nature Reserve, the first reserve created in Portugal (1975) and one of the country's most emblematic wetlands. With 2,300 hectares of salt marshes, salt marshes, estuaries, and brackish waters, this natural refuge stretches between Castro Marim and Vila Real de Santo António, revealing a unique landscape where biodiversity, tradition, and rivers coexist in perfect harmony.

In the heart of the Algarve, perched on a hill on the right bank of the Guadiana River, Castro Marim Castle holds centuries of history and battles. Although human presence in the region dates back to prehistoric times, it was here that Romans and Muslims found a strategically valuable vantage point, taking advantage of its privileged position. The imposing fortification you can visit today (for a small fee) was built in the 13th century by order of King Dinis, serving as a defensive bastion against invasions and as a watchful sentinel on the border with Spain. At the top, the reward is a breathtaking panoramic view: the town of Castro Marim at your feet, the shimmering salt flats, the bridge connecting Portugal and Spain, and, in the distance, neighboring Ayamonte.

Castro Marim Castle was strategically built in the 13th century on a hill on the right bank of the Guadiana River. Currently, only the remains of the castle remain, including four towers, a gate, the ruins of the 14th-century Church of São Tiago, the Mayor's Palace, and a few houses.
