Running from 14 March through 30 June 2026, Superhéroes Marinos: Misión Rescate Oceánico turns a visit to Palma Aquarium into an underwater adventure mission for young explorers. Each child receives a Pasaporte Marino at the entrance and is dispatched on a series of missions across the aquarium's tanks and habitats. Along the route, young heroes discover the extraordinary real-world superpowers of marine species — echolocation, bioluminescence, regeneration — and collect illustrated cards inspired by each animal they find. The trail is designed to make children look carefully and think, not just walk past glass panels. Eco-tips woven into each station tackle plastic pollution and ocean threats in language that lands with kids without lecturing. Practical info: Open daily 09:30–18:30, last entry 17:00. Standard aquarium ticket includes the Superhéroes Marinos programme — no separate booking needed. Adults from €30.50, children (3–12) from €19.50, under-3s free. A 15% discount applies to tickets bought after 14:00. Last weeks to catch it: the exhibition closes 30 June — if you haven't taken the kids yet, this week is the moment.
