The Lisbon Oceanarium is celebrating Halloween with a special Halloweek promotion, offering 2,500 tickets at a reduced price of €15 for visitors of all ages.
Available to purchase online from October 22 to 31, the discounted tickets can be used for visits between October 22 and November 1, 2026, with no restrictions on age groups or visiting times.
The initiative invites families and friends to explore the fascinating world beneath the waves, discovering marine habitats and the creatures that inhabit them.
From the Oceanarium’s impressive central aquarium to its colony of Magellanic penguins, visitors can observe a wide variety of marine species and learn more about their behaviour and ecosystems.
The Halloween promotion also offers an opportunity to discover the temporary exhibition Sea Monsters, which takes visitors on a journey through millions of years of marine history.
Located in the Oceanarium’s main entrance hall, the exhibition features life-sized models of some of the most remarkable predators ever to inhabit the oceans, offering an insight into the extraordinary creatures that once ruled the seas.
Rather than focusing on traditional Halloween scares, the Oceanarium is using the occasion to highlight the diversity of marine life, past and present.
The Halloweek promotion is available exclusively online, with just 2,500 tickets offered at the special price of €15.
