Océanopolis

Océanopolis in Brest is a major educational destination for ocean life, located at the Port de Plaisance du Moulin Blanc. Recognized as the largest open-air aquarium in Europe, it features 77 aquariums and habitats for 1,000 species, including penguins and sharks. The facility is organized into tropical, temperate, and polar pavilions, along with an otter trail. It is open daily from 9:30 AM to 7:00 PM, with a recommended visit duration of 3 to 5 hours. Admission tickets start from €24.90.

However, visitors should be aware that due to ongoing renovations, only two zones—one indoor and one outdoor—are currently accessible. Full reopening is expected by November 2026. One visitor review notes that full-price admission applies despite this reduced access, with no compensation offered.

For those planning a broader itinerary, the "Ocean Pass" is available from July 4 to August 30, 2026. This summer promotional ticket grants access to Océanopolis as one of four must-see sites in Brest, alongside the National Maritime Museum, the Museum for the Ocean 70.8, and the National Botanical Conservatory of Brest. The pass includes unlimited public transport and offers discounted rates: €39 for 24 hours and €44 for 48 hours for adults, with child rates at €19 and €22 respectively. This attraction serves as a key resource for understanding marine biodiversity, combining entertainment with scientific education for families and tourists alike.
