Peniche is known for its crashing waves and rocky coastlines, but it’s also a prime spot for underwater exploration. Its location in Portugal’s Norte Region means clear waters, diverse marine life, and an abundance of scenic seascapes. We particularly like the Peniche: Berlengas Island Catamaran Tour + Snorkeling, which combines a smooth sailing experience with the chance to see dolphins and explore the UNESCO Biosphere Reserve. This tour’s inclusion of snorkeling equipment makes it a solid choice for both beginners and seasoned snorkelers alike.
Below, we’ll explore the two best snorkeling tours in Peniche. Each offers its own flavor — from a relaxing boat trip to an adventurous cave exploration — helping you pick the right experience for your style and interests.

Coming in second, the Peniche: Berlengas Island Caves Tour and Snorkeling offers a more adventurous approach to exploring Berlenga’s waters. For about $51, this experience combines snorkeling, a visit to the island’s famous caves, and a glass-bottom boat ride — an excellent way to see underwater formations without getting wet.
The tour begins with a cave exploration, where you can marvel at the towering rock formations, sea arches, and caves that make the archipelago so special.

How to Choose Your Snorkeling Adventure in Peniche
Picking the right snorkeling experience depends on your interests and travel style. If you prefer a relaxed boat trip with dolphin sightings and scenic trails, the Peniche: Berlengas Island Catamaran Tour + Snorkeling is your best bet. It’s good for families, couples, or anyone wanting a gentle introduction to snorkeling in Portugal’s protected waters.
On the other hand, if you’re eager to incorporate caves, geological formations, and a more comprehensive underwater exploration, then the Berlenga Island Caves Tour and Snorkeling is ideal. It offers a richer, more adventurous experience that suits those comfortable with a bit more activity.
Timing is also key — both tours run about four hours, so check availability early, especially in peak season. Budget-wise, the catamaran tour is slightly cheaper but still offers excellent value, especially considering dolphin sightings are often included.
Final Thoughts
Peniche’s snorkeling options cover a range from laid-back boat rides to adventurous cave explorations. For a relaxing journey with scenic views and dolphin sightings, the catamaran tour shines.

Whatever your choice, both tours promise a memorable way to experience Peniche’s stunning marine environment. Be sure to book early, especially in summer, to secure your spot. Little things like bringing your own sunscreen, a waterproof camera, and a dry towel can make your day even better. Dive in, explore, and enjoy the clear waters of Portugal’s north coast.
