Overview

This is a 3-hour boat trip along the Algarve coast departing from Portimão Marina on an eco-friendly solar-powered catamaran. The vessel offers comfortable lounge seating, a deck, a bar, and restroom facilities for passenger convenience. The tour sails past the Fort of São João do Arade, a medieval coastal fortification, and the Ponta do Altar Lighthouse, a small white building with a red lantern located on a promontory at the entrance of Portimão harbor. It also passes a small islet known as an Important Bird Area, where herons nest in spring. The route continues along the coast past Torre da Lapa, a 16th-century watchtower used historically to spot corsair ships. Weather permitting, the catamaran enters the Algar de Benagil, one of the Algarve's deepest caves, allowing onboard viewing of this well-known beach cave. On warm days with calm seas, passengers may take a swim except on sunset departures. Passengers should bring a swimsuit and towel if they wish to swim. The tour runs with zero emissions, making it an environmentally friendly option for coastal sightseeing in the Portimão area. All fees and taxes are included in the price.

Itinerary

1

Fort of São João do Arade

The Fort of São João do Arade, also known as the Castle of Arade, is a medieval fortress. Initially, a watch tower was built during King John II of Portugal's reign. Around 1520, after Ferragudo was established, the castle was likely surrounded by a defensive wall constructed over older walls. The fort dates back to the Philippine Dynasty and was intended to protect the peninsula's coast from pirate and privateer attacks.

2

Ponta do Altar Lighthouse

This lighthouse has a unique design featuring a small square tower connected to a one-story caretaker's house. The house, painted white with exposed stones and a red tiled roof, resembles a small schoolhouse and supports a red lantern on its terrace. It stands on a promontory used since prehistoric times for pagan rituals, located on the eastern side of Portimão's port entrance. Proposed on June 21, 1884, it began operation on January 1, 1893. The tower is 10 meters tall and 2.7 meters wide, originally using a white oil-fueled light combined with two smaller lights at the harbor entrance.

3

Small Islet Bird Area

This islet covers just 0.16 hectares and is designated as an Important Bird Area (IBA) because it serves as a nesting site for herons. It is particularly notable in spring when colonies of Cattle Egrets and Little Egrets nest there, covering the islet's top with white nests.

4

Torre da Lapa Watchtower

Torre da Lapa was likely constructed in the 16th century as part of a coastal watchtower system for the Algarve. For centuries, local men took turns watching the coast for corsair ships, mainly from North Africa. In case of threat, they used a bell, smoke signals, or lit fires at night to warn people to secure their belongings and safety.

5

Deep Cave Entrance

This cave is among the deepest in the area. Access is only possible when weather conditions allow. Entering the cave provides a notable experience.
