Arrábida: Portugal's Hidden Shores & Sea Cave Discovery

The tour captain and tour guide were excellent. I gave them a 5 star as I don't want to ruin their status, but the boat is not the one pictured. You have to straddle a large bumper for the entire ride and may not be comfortable for some. When booking the trip, the maximum was 8, but as they changed the boat, the tour was then made for 12 people. We were not looking for that kind of a tour, but again the staff was very professional, and the captain navigated the waters well. The scenary, beaches stops and caves were wonderful. The water was too cold to swim.

Excellent high speed boat. Brilliant host who was very knowledgeable on the environment and history of the area. Enough time for swimming and snorkelling.

Amazing day with fantastic crew around the stunning Serra da Arrábida! 😍 It was unforgettable! From the cliffs and crystal-clear turquoise waters to the hidden coves and beaches that can only be reached by sea. Thank you all!

This was a very worthwhile trip. Seeing the coastline from the water was eye opening; it was really beautiful. In addition, seeing the more private beaches and having a chance to swim made this feel like an interactive experience (vs. viewing from a distance). Our guide, Katarina, was very knowledgeable and patiently answered all of our questions. She kindly helped people with snorkel masks and life vests and had a really positive attitude; you can tell she loves her job. One thing to note- there is the opportunity to snorkel, as listed. But be advised, this is the Atlantic, not the Caribbean. There are no coral reefs or tropical fish here. If your main goal is to snorkel, this isn't for you. If it is to enjoy the views of a gorgeous national park, then definitely sign up.

We had an incredible time exploring the stunning coastline and sea caves of Sesimbra on our boating tour. The natural beauty of the cliffs, hidden beaches, and crystal-clear waters was absolutely breathtaking. Every twist and turn of the coastline brought a new surprise, from dramatic rock formations to peaceful, secluded coves. Our guide, Caterina, made the experience truly unforgettable. She was incredibly knowledgeable—not only about the geology and marine life but also about the rich history of the region. Her passion for Sesimbra’s natural environment and heritage shone through in every story she told and every question she answered. Whether you’re into nature, photography, history, or just soaking up the beauty of Portugal’s coast, this tour is a must. Thank you, Caterina, for such a memorable adventure!

Great experience! Lots of fun and very informative :) group was 11 people and boat felt comfortable! It was me my husband and our four year old who they had a life jacket for immediately! Easy to find and parked right on the pier.

The tour guide and boat operator were both incredibly friendly and very well informed about the local area with some very good insight to the history of the beaches. It was a fun relaxing trip with ample time to swim/ snorkel between locations highly recommend.

This was an absolutely phenomenal experience! Catarina was so knowledgeable and kind and the scenery was just gorgeous!

Such a nice tour on the boat with some snorkelling and visits to different coves and beaches. Catarina who guided us was very approachable and knowledgable.

Children enjoyed jumping off to swim. Beautiful view of cliffs at coast. Liked explanation for cliff formations.
