If you’re considering taking a boat trip along Portugal’s coast, the Sesimbra: 3 Bays Tour might just catch your eye. From what I’ve gathered, it’s a popular choice for those wanting to see some of the most beautiful, untouched beaches in the Lisbon District without the hassle of planning it all themselves. The idea of floating along crystal-clear waters and stopping for swims in serene bays sounds pretty appealing, especially if you’re craving a relaxing day out on the water.
What really stands out about this experience is the promise of stunning views and the chance to explore less crowded, natural landscapes that are often hidden from larger tourist crowds. Plus, the inclusion of snorkeling gear and guided commentary makes it feel like more than just a boat ride — it’s an adventure with a bit of learning and play mixed in. That said, it’s not a lengthy trip, so if you’re after a full-day excursion, this might be more of a quick escape.
One thing to keep in mind is that this is a private group experience, which means it’s ideal if you prefer a more personalized vibe rather than a big, noisy tour. However, the 1.5-hour duration is relatively short, so if you’re looking for a full day of exploring, you’ll need to plan accordingly elsewhere. This tour is best suited for those who appreciate scenic views, calm waters, and a relaxed pace.

The Starting Point and What to Expect
The tour begins at Cais do Espadarte, close to the naval club in Sesimbra. From there, you’ll hop aboard a boat that will carry you along the Costa Azul, or Blue Coast, renowned for its pristine beaches and rugged coastline. The duration of 1.5 hours makes this a perfect quick escape, especially if you’re tight on time but craving a taste of the sea.
Once on board, your guides will take you on a route that covers the entire bay of Sesimbra, including Mula Bay. This particular bay is famed for its crystal clear waters, which are perfect for observing marine life from the surface. Many reviews highlight how the water clarity makes snorkeling quite enjoyable, even for beginners.
Visiting Mula Bay and Its Marine Life
One of the standout aspects here is the chance to see marine species in their natural habitat. The waters are calm and transparent enough for snorkelers to spot small fish and other sea creatures, which adds a layer of interest for those who enjoy marine environments. The guides are attentive and will encourage you to explore the waters whenever you feel comfortable.
Ribeiro do Cavalo Beach
Next, you’ll visit Ribeiro do Cavalo, the most famous beach in Sesimbra. It’s a spot praised for its breathtaking landscape — a mix of golden sands framed by cliffs and lush greenery. Here, you can opt to stop for a swim or simply soak in the views from the boat. The calm waters make it a safe and refreshing place to take a break. Many travelers mention that this stretch is the highlight of the tour, especially for the picturesque scenery.

The route also includes visits to Tamboril Cave and Baia do Frade. While I haven’t found detailed descriptions of what exactly you’ll see inside these spots, their mention hints at interesting geological features and scenic coves. These stops are designed for short breaks for diving or snorkeling, adding variety to the journey.
Stops for Swimming and Snorkeling
Part of the charm of this tour is the opportunity for spontaneous swimming. The guides provide snorkeling equipment, and they’re happy to assist if you’re new to the activity. Several reviews highlight how this flexibility allows everyone to enjoy the water, whether for a quick dip or a more extended underwater exploration.
The Experience from the Guides
Reviewers consistently mention the friendly, informative guides who keep the trip engaging, sharing interesting facts about the landscape and marine life. Their presence enhances the experience, making it more than just a boat ride — it’s about appreciating the coastal environment with knowledgeable hosts.
The Price and What You Get
At $284 for up to 8 people, this tour offers a private experience that feels more exclusive than large group excursions. The cost includes guides, lifejackets, snorkeling gear, insurance, and the boat itself. That makes it a pretty reasonable deal considering the personalized service and the scenic highlights.
Considerations and Potential Downsides
While many reviews rave about the stunning scenery and calm waters, a few mention that the trip is quite short. If you’re after a full-day adventure or multiple stops, this won’t satisfy that craving. Also, since it’s a private group, the experience can be more relaxed, but that also means you’re limited to this specific route and duration.
Weather can also be a factor — on windy days, some travelers felt the boat ride could be bumpier, though this is typical for any sea trip. Make sure to bring sunscreen, a sun hat, and water, especially if you plan to stay out in the sun for the entire duration.
Who Should Consider This Tour?
This experience is ideal for nature lovers who want a quick but scenic escape to enjoy clear waters and untouched landscapes. It’s great for small groups or couples looking for a personalized, relaxed outing. If you’re traveling with friends or a partner and want a memorable, scenic boat ride without a long commitment, this tour will suit you well.
