Visit Nausicaá: The National Sea Centre

Located in Boulogne-sur-Mer on the Opal Coast, Nausicaá stands as Europe's largest aquarium and one of the most visited sites in the Hauts-de-France region. This National Sea Centre offers a fascinating dive into the heart of the oceans through three immersive routes that delight young and old alike. With more than 58,000 marine animals representing 1,600 different species, Nausicaá combines discovery, environmental awareness and unique experience. Whether you're passionate about marine life, visiting with family or simply curious, this exceptional place promises a memorable day facing the wonders of the underwater world.

Nausicaá is not just an aquarium, it's a true invitation to journey into the heart of the oceans. Recognized as the National Sea Centre in 1991, this exceptional establishment combines wonder and education to raise public awareness about marine ecosystem preservation. With its main 10,000 m³ seawater tank, one of the largest in the world, you'll discover majestic rays, impressive sharks and breathtaking marine biodiversity evolving in a meticulously recreated environment.

The visit to Nausicaá unfolds across three complementary thematic routes that plunge you into different facets of the marine world. The "High Seas Journey" route confronts you with oceanic immensity before a spectacular 100 m² viewing window, while "In the Eye of Climate" helps you understand the crucial role of oceans in climate regulation. Finally, "Shores and People" explores the relationship between humanity and the sea, from the Mediterranean to Californian coasts. This global approach makes Nausicaá much more than an attraction: it's an unforgettable educational experience.

Located facing the sea on Boulevard Sainte-Beuve, Nausicaá enjoys a privileged location in Boulogne-sur-Mer. The Hauts-de-France region offers numerous excursion possibilities to extend your stay, including discovering Lille, Calais or Amiens.

Inaugurated on May 18, 1991, Nausicaá was born from a visionary project carried by the local community and the Nord-Pas-de-Calais Region. From its beginnings, the centre adopted a unique mission: to reveal the wonders of the oceans while raising public awareness about the environmental challenges that threaten them. The name "Nausicaá" refers to the princess from Homer's Odyssey, a symbol of hospitality and curiosity, values that still resonate today in the spirit of the place.

In 1999, UNESCO awarded Nausicaá the prestigious title of Centre of Excellence for marine environmental education, an extremely rare recognition for an aquarium. This international distinction underlines the importance of its educational mission and its efforts in marine conservation. Over the years, Nausicaá became a world reference, welcoming millions of visitors from around the globe.

The year 2018 marked a major turning point with the inauguration of the "Grand Nausicaá" extension, the result of a 70 million euro investment. This transformation doubled the reception area and allowed the creation of the main 10,000 m³ tank, which instantly became one of the world's largest aquariums. This expansion made it possible to accommodate 10,000 new marine animals and enrich the experience with spectacular immersive routes, propelling Nausicaá to the rank of undisputed European leader.

High Seas Journey: into the heart of the deep blue

Nausicaá's flagship route transports you off the coast of Colombia, around Malpelo Island. Before you, a spectacular 100 m² viewing window offers a striking panorama of the 10,000 m³ tank where grey sharks, giant manta rays, schools of shimmering fish and many other pelagic species evolve. An 18-meter-long tunnel allows you to completely immerse yourself, surrounded by marine creatures gliding majestically above your heads.

The immersive scenography faithfully reproduces the open sea ecosystem with its interplay of light, currents and diverse fauna. You'll understand the complex interactions between different species and the importance of preserving these oceanic sanctuaries. The spectacle of feeding rays and sharks constitutes one of the day's highlights, offering a fascinating glimpse into the feeding behaviors of these iconic animals.

In the Eye of Climate: understanding to act

This educational and interactive route plunges into the heart of the global climate machine. You'll discover the fundamental role of oceans in regulating Earth's climate, their CO2 absorption capacity and the threats weighing on these fragile balances. Captivating multimedia installations illustrate climatic phenomena, from the water cycle to ocean acidification.

Far from settling for an alarmist assessment, this route shows you your power to act in daily life. Eco-responsible gestures, sustainable consumption, biodiversity protection: so many keys to becoming an agent of change. The experience aims to be resolutely optimistic, demonstrating that each individual action can contribute to preserving our blue planet's future.

Shores and People: a coastal tour of the world

This route takes you on a journey around the world's coastlines, from the North Sea to tropical coasts, passing through the Mediterranean and Californian shores. Each space faithfully recreates a specific coastal ecosystem with its fauna, flora and particularities. You'll discover the Cape penguin beach, the California sea lion area, and the tropical lagoon with its multicolored corals and exotic fish in vibrant hues.

The touch pools constitute one of families' favorite attractions. Under the supervision of passionate educators, you can gently stroke rays, starfish and other harmless species. These privileged moments create a unique connection with the marine world and naturally raise awareness about the importance of its preservation. The route also explores the ancestral relationship between humans and the sea, from traditional fishing techniques to contemporary overfishing challenges.
