Arrival and Preparation

The tour begins at Batnavó Tours, where a brief safety briefing kicks things off. This 10-minute chat ensures everyone knows how to stay safe and respect the environment. We appreciated that the company provides life jackets, water, and a first aid kit, showing their focus on safety and comfort. The boat ride itself is short but exhilarating, riding out to the caves with a skipper at the helm, ready to navigate the rocky coastlines and guide us into the underground spaces.

The Scenic Boat Ride and Cave Exploration

The highlight of the tour is the boat cruise through the caves, with several stops at significant sights like Ribeiro do Cavalo Beach and Praia da Mijona**. The guide, who speaks Portuguese, English, and Spanish, shares insights into the geological processes that formed these caves—something we found particularly engaging. As we entered the caves, the lighting was carefully arranged to accentuate the spectacular rock formations, creating an almost mystical atmosphere.

Many reviewers mention how the formations look like “natural sculptures,” with some describing the hanging stalactites and rising stalagmites as “impossibly detailed.” The caves themselves vary in size and shape, some with narrow passages, others more open, giving a sense of exploration and discovery. The guides emphasize the importance of respecting the environment—avoiding touching the formations or leaving trash—something we appreciated for the preservation of this fragile habitat.

Photo Opportunities and Underwater Adventures

Photographers will love the perfect scenery for capturing dramatic images of rocks and caves. The tour includes a couple of dedicated photo stops, giving visitors time to frame their shots of the fascinating geological features. After the cave exploration, the boat pauses at scenic spots along the coast for more sightseeing and scenic views, which serve as excellent backgrounds for relaxed photo moments.

When the boat anchors in a calm cove, you’re encouraged to swim in the clear waters. Many guests mention how refreshing it is to take a dip after the cave tour—an ideal way to cool off and enjoy the natural beauty of Portugal’s coast. The water is often described as crystal-clear, making the swim both safe and visually stunning.
