4 Amazing Snorkeling Spots in Portugal You Need to Explore

 

Baixa do Ambrósio, Santa Maria, Azores


Portugal often gets overlooked as a snorkeling destination, overshadowed by the Mediterranean or tropical hotspots. But between the Atlantic archipelagos and the mainland coast, this country hides some genuinely world-class underwater experiences. Here are four spots worth packing your mask and fins for.

Santa Maria, Azores

If you're chasing the best snorkeling Portugal has to offer, the Azores are hard to beat, and Santa Maria, the southernmost island of the archipelago, might just take the crown. The star attraction here is Baixa do Ambrósio, famous for manta ray sightings, a rare treat in European waters.

Santa Maria also holds a unique distinction: it's the most reliable spot in Europe to encounter whale sharks during summer months, when warm currents bring plankton blooms that attract these gentle giants. Visibility here regularly exceeds 20 meters, and the volcanic rock formations create dramatic underwater landscapes that make every dive feel like an expedition.

The other Azorean islands also deliver exceptional snorkeling, and there's a clear reason why: the Azores' open-ocean location, far from mainland pollution sources and industrial runoff, keeps the water noticeably cleaner. Divers and snorkelers alike consistently notice better visibility and healthier marine ecosystems compared to continental Portugal, a difference you feel the moment you put your face underwater.




Madeira

Madeira offers a compelling mix of excellent snorkeling and mature tourist infrastructure, meaning you get pristine waters without sacrificing comfort or accessibility. Its more southern latitude keeps water temperatures noticeably milder year-round, even in winter, making it a viable destination outside the typical summer window.




Beyond the main island, Porto Santo (part of the Madeira archipelago) deserves its own trip. Its calmer, sandier bays offer a different snorkeling character than Madeira's volcanic coastline, with golden sand seafloors that make for excellent underwater photography conditions and easier entry points for beginners.




Berlengas Islands

Located off the western coast near Peniche, the Berlengas present a wilder, more unpredictable snorkeling environment. The open Atlantic swell here means conditions can turn choppy fast, so timing matters more than at other spots. On calm summer days, though, the Berlengas transform into a must-explore destination.

The islands sit within a nature reserve, which has helped preserve rich marine biodiversity, including colorful sponges, diverse fish species, and dramatic granite rock formations that plunge underwater. It's a spot that rewards patience: check the forecast, wait for a flat-calm window, and you'll be rewarded with some of the clearest water on the mainland coast.




Costa da Caparica

I'll end with the spot closest to my heart. Costa da Caparica is a well-known beach just south of Lisbon, and most visitors have no idea it hides decent snorkeling, specifically around the longest pier and near Praia de Santo António. This is where I first put on a mask at age 14, and it's the place that quietly launched a lifelong obsession with the underwater world.

It's not the Azores. The visibility is more modest, and you won't find manta rays or whale sharks. But there's something special about revisiting the waters where it all began, watching small fish dart around the pier's pilings, and remembering that every diver's journey starts somewhere unglamorous and local. If you're ever near Lisbon, it's worth a look, if only to understand how accessible curiosity about the ocean can be.

Snorkeling Adventure Okinawa

Image
I arrived in Okinawa by plane from Osaka, after visiting the Great Barrier Reef in Australia, where I snorkeled in three places, and I'll share one of them here: Green Island, Great Barrier Reef  I'll soon write a post dedicated to the Great Barrier Reef. On this trip, I flew more than once around the world, accompanied by my youngest son, Miguel. In addition to Japan and Australia, we visited Dubai and Singapore. It was a demanding and challenging trip, but it also served as a bonding opportunity for my son. During the trip, he was able to visit three amusement parks: Universal Studios in Singapore and Osaka, and Aquaventure Waterpark in Dubai. We spent almost a week in Okinawa and managed to snorkel in several places: Kibougaoka Beach  Cape Maeda  Blue Cave Tokei Hama  Seragaki Beach  Diamond Beach Mermaid's Grotto  Nakama Sunset Beach  Cape Maeda was perhaps our favorite spot. The water was crystal clear, and the coral was incredible. The famous Blu...

Anicha Stone: The best snorkeling spot in Arrábida Natural Park

Image
Anicha Rock is a rock located in front of Portinho da Arrábida beach, but on the side of Creiro Beach. You can swim to it if you're experienced and check the currents that day. I like to swim in the two hours before low tide, as the water is calmer, and since the point is still some distance away, the shallower water makes me feel safe. Kayaking is also a good option, and it's recommended at low tide to be able to park the kayak. At low tide, it is easy to park the kayak I really like kayaking from Figueirinha beach, more towards Setúbal, to Anicha Rock. It's about 2,800 meters by kayak, but it passes Galápos, Galapinhos, and Coelhos beaches, where you can stop for a swim or snorkeling. The scenery along the coast is magnificent Near Pedra da Anicha, the concentration of fish is very high, and the coastal side is very protected, resulting in excellent snorkeling conditions. Lots of fish near Anicha Stone Great underwater beauty Watch a video of snorkeling at this magnificen...

Octopus: the Master of Disguise

Image
I woke up early to go to Costa da Caparica. It's a good spot for snorkeling in the summer and is a 15-minute drive from my house in Lisbon. The water was a little cold, but the visibility was good. I found an octopus and dove in to observe it. It didn't run away very far, but what I found strange was that it was disguised as the color of the rock, and when I got very close, it turned white and adopted a different shape, like a star. I did a second dive, and it behaved exactly the same way; I even noticed that its texture changed when it turned white. It didn't make sense to me that it would lose its camouflage of the rock's color. Until I realized what it was doing: it was disguising itself as a starfish. This is a defensive mimicry strategy, since there are starfish of that color in the area. Why the octopus behaved this way: What I witnessed that morning was a remarkable example of  octopus camouflage and mimicry , two of the most advanced survival strategies in the a...
