An In-Depth Review of the Algarve Coast Boat Tour

What the Experience Looks Like

Starting point for this tour is conveniently located in Portimão, right in front of the ruins of the São Francisco Convent, on the riverfront. From there, you board a new, environmentally friendly boat, typically with no more than 23 people aboard, which means you’ll be able to move around easily and get unobstructed views of the coastline.

The two-hour guided trip is a lively blend of sightseeing, storytelling, and occasional dips in the sea, weather permitting. Your guides—often praised for their friendliness, knowledge, and multiple language skills—bring the coast alive with stories about the caves, beaches, and historical points of interest like the Fort of Santa Catarina and Ferragudo Castle visible along the route.

The Routes and Stops

The main destination is the Benagil Sea Cave, a must-see natural wonder with its iconic dome-shaped roof and the small beach inside. Passengers typically spend enough time inside the cave for everyone to take photos and soak in the view. The guides are attentive, even offering to take pictures of guests, which is a real plus for those wanting memory keepsakes.

Beyond Benagil, the boat glides past about 20 caves and several deserted beaches, each with unique rock formations and arches that stir the imagination. Travelers often describe the scenery as “amazing,” with one reviewer noting how the coast is far more impressive from the water than from land.

The tour also includes a special stop at Praia da Marinha, one of the Algarve’s most famous and beautiful beaches, with its striking arches and cliffs. Weather and sea conditions permitting, you’ll have the opportunity to take a swim here—a highlight for many. Reviewers have raved about the “amazing” time spent swimming and the chance to cool off in the Atlantic.

The Guides and the Experience

Guides like Guilherme and Andre frequently receive praise for their detailed explanations, friendly demeanor, and their willingness to help with photos and questions. Many reviews highlight how guides make the experience fun and informative, spinning stories about the caves’ formations and the coast’s history.

For example, one reviewer mentions, “Gabriel was knowledgeable and made the experience fun,” while another notes, “the guides were great, funny, and gave us lots of info about the caves and beaches.” This kind of personal attention elevates the tour from a simple boat ride to a memorable, educational outing.
