Full Description
Portimão Marina, the starting point
The cruise starts at Portimão Marina, on the Arade river, one of the easiest departure points on the western Algarve. Check-in takes place at the operator's counter in the marina up to 30 minutes before departure, and you show your booking confirmation and identification. Seats are assigned by the crew for safety and balance, so there are no reserved seats.
If you are looking for a Portimão boat trip that combines caves and dolphins, this one is designed for it, and the marina has cafes and parking nearby. Portimão is also a good base for the Praia da Rocha beaches and the fishing quarter, so you can plan a full day around the cruise.
Benagil Caves and Algar de Benagil
The Benagil Caves are the highlight of the coastline east of Portimão. The famous Algar de Benagil is a sea cave with a round skylight in its roof and a small beach inside, and the boat enters it for a photo. Local rules limit the stay to a few minutes and do not allow passengers to disembark onto the cave beach.
The marine police can forbid entry when the sea is rough, in which case the cave is viewed from outside. A boat tour of the Benagil Caves gives a different view from a kayak or a beach visit because you also see the cliffs, arches and smaller caves along the way, explained by the biologist.
Dolphin watching with a marine biologist
After the caves the boat leaves the coast and sails into the Atlantic to look for dolphins. The marine biologist explains what to look for, which species are usually seen off the Algarve and how they behave around boats. The chance of spotting cetaceans is high on most days, but dolphins are wild and sightings are never guaranteed.
When they appear, they often swim beside the bow and jump in the wake, so keep your camera ready. If you want to know the best time for dolphin watching in the Algarve, mornings and calm days tend to be best, and the crew chooses where to go from conditions on the day.
Marinha Beach and the swim stop
The route passes Praia da Marinha, one of the most photographed beaches in Portugal, with ochre cliffs and natural arches rising from turquoise water. Live commentary explains how the limestone was eroded into stacks, arches and grottoes, and you see how sea life uses the rocks.
When the sea is calm, the boat stops in clear water for a swim, so bring swimwear, a towel and sunscreen. Bring a jacket and hat as well, because it can be cooler out at sea. Raincoats are provided, and there is a toilet on board.
