The Fort of São João do Arade, sometimes referred to as the Castle of Arade, is a medieval fortification. The first fortification on the site consisted of a watch tower erected in the reign of King John II of Portugal. Later, following the settlement of Ferragudo (around 1520), it is believed that the castle was encircled by a defensive wall (built on the rudimentary walls of the older walls). The origins of the Fort of Arade date back to the Philippine Dynasty, to defend the coast of the peninsula from attacks by pirates and privateers in service to the Crowns of northern Europe.
Ponta do Altar Lighthouse
The lighthouse, of unusual design, consists of a small square turret attached to a one-story caretaker's house. It supports a red lantern on its terrace. The house, often compared with the appearance of a small schoolhouse, is painted white, with exposed stones and a red tiled roof. It is located on a promontory, used since prehistory for pagan rituals, on the eastern side of the entrance to the port of Portimão. The Ponta do Altar Lighthouse was first proposed by Ricardo Peyroteu on June 21, 1884. It started operations of 1 January 1893. The tower is 10 meters high and 2.7 meters wide. The original light was white and used oil as the fuel source. It combined with two smaller lights at the ends of the two moles at the entrance to Portimão harbour.

Our trip with Algarve Sunboat was absolutely magical! Cruising silently along the stunning coastline was an unforgettable experience — peaceful, relaxing, and simply beautiful. The guide on board was wonderful: knowledgeable, kind, funny and made the whole journey feel special. The boat is super comfortable, with benches to sit and tables. A toilet and a bar on board! We went inside of the caves which was such an experience. If you’re looking for a unique way to explore the Algarve, I can’t recommend this experience enough!

The Captain and Guide couldn’t have been friendlier and so welcoming & informative. Would totally recommend and can’t wait to do it again. Thank you Algarve Sunboat for a very memorable experience.

We loved the two crew members who were very knowledgeable, funny, informative and handled the boat with such skill. The boat being solar powered was great, very comfortable and the small group made it very personal. We would highly recommend this company.
