If you’re planning a trip to Portugal’s Norte Region and looking for an experience that combines natural beauty with a touch of adventure, the Berlenga Island Caves tour might catch your eye. From what we’ve gathered, this 4-hour excursion offers a chance to see the island’s impressive cliffs, explore underwater scenery, and visit some of the archipelago’s iconic caves—all from a comfortable glass-bottom boat and on your own for snorkeling.

The crystal-clear waters of Berlenga Island promise good visibility for snorkeling, and the glass-bottom boat ride offers a fascinating peek into the underwater world without getting wet.

The Itinerary Breakdown
The tour kicks off at the Berlengoest meeting point, located conveniently in Peniche’s marina. From there, you’ll board a catamaran that takes you across the water to Berlenga Island. The cruise itself is a highlight, providing ample opportunities to snap photos of the rugged coastline and keep an eye out for marine life.
Once on the island, the highlight is the 25-minute glass-bottom boat ride. This part is perfect for anyone who wants a taste of the caves without the physical exertion of climbing or extensive hiking. It’s a chance to marvel at formations like the blue cave and the Elephant’s Trunk rock, each with its own story and charm.
After the boat ride, you’ll have about 1.5 hours of snorkeling available. The activity is self-guided, with rental gear including fins, masks, and tubes. You can snorkel either at the beach or near Fort S. João Batista, both offering good underwater visibility. We’ve heard from some travelers that the snorkeling experience is straightforward and enjoyable, especially if you enjoy exploring marine environments at your own pace.
The Cave Visit
The cave exploration is quite a visual treat. The glass-bottom boat makes it easy to see the caves’ interior and the stunning rock formations. The caves are a major draw, especially considering the imposing cliffs and natural arches that surround the island. The tour’s duration (about 30 minutes on the boat) means you get decent views without feeling rushed, but it’s not an exhaustive cave expedition—think of it as a snapshot of Berlenga’s geological wonders.
The Snorkeling Experience
Self-guided snorkeling is a flexible, laid-back part of the tour. You’re provided with the gear, but not wetsuits, which means if you’re sensitive to cooler waters, you might want to bring your own or rent a wetsuit elsewhere. The waters near Fort S. João Batista and the beach are said to be clear, with decent underwater visibility, making it ideal for those new to snorkeling or just wanting to float around and enjoy the marine scenery.
One review mentions that “the guides are very friendly,” which can make a difference when navigating the caves or just feeling comfortable in the water. The freedom to snorkel where you want and how long you want—within the overall timeframe—is a definite plus.
