An aquarium on the lower level of the Val d'Europe shopping center in Serris, one RER stop from the Disney parks. Kids walk through a tunnel under a 600,000-liter cold-water Atlantic tank as sharks pass overhead, then watch king and gentoo penguins swim. Other zones cover the Amazon, Asia, a tropical zone, the French coast and a shark island, with staff talks and feedings through the day.
