Glass-Bottom Boat Tours with Els Blaus de Roses on Costa Brava

Read the full experience

On the sun-drenched waters of Spain’s Costa Brava, Els Blaus de Roses offers a marine adventure that blends natural spectacle with serene exploration aboard the Aquarium II, a glass-bottom boat uniquely designed for immersive viewing beneath the waves. Departing from Roses, this trip navigates the wild beauty of Cabo de Creus Natural Park, an exceptional reserve famed for its rugged coastline and clear Mediterranean waters. The journey reveals a vivid aquatic world flourishing beneath the boat’s transparent hull. Passengers witness dense clusters of bright orange corals swaying in the current, shoals of silvery fish flickering like kinetic art, and sea stars quietly gripping rocky outcrops. This underwater panorama provides a rare window into the park’s rich marine biodiversity without the need to get wet. A highlight of the tour is the approach to the Cueva Secreta, a hidden sea cave accessible only by boat. Its shadowed mouth contrasts with the sunlit cliffs, invoking a mysterious allure that few visitors experience firsthand. Nearby, playful dolphins often join the voyage, their energetic leaps and spins sparking awe and laughter that echo across the waves. Above water, the spectacle continues. Cabo de Creus’ cliffs rise sharply from the sea, shaped by millennia of wind and wave. Their warm ochres and reds stand in striking contrast to the deep blues of the Mediterranean, framing the journey with scenic grandeur. Els Blaus de Roses specializes in creating accessible, family-friendly trips that connect travelers directly with the natural wonders of the Costa Brava. Their blend of educational insight and comfortable cruising makes this trip a standout for visitors seeking a unique way to engage with one of Spain’s most impressive marine environments.
