The notes
What the sources say (research)
- Daily 10:00–20:00, last entry 19:00; re-read on the operator page on 26 October 2026 and unchanged. [oceanario.pt/planear-visita, 26 Oct 2026]
- Four days a year differ: 24 and 31 December 10:00–19:00 (last entry 18:00) and 25 December and 1 January 11:00–20:00 (last entry 19:00). It does not close on Christmas Day. [oceanario.pt, 26 Oct 2026]
- Prices depend on entry time: morning (10:00–11:30) adult €29.90, child 3–12 €17.70, 65+ €19.90; early afternoon adult €27.70, child €16.60; late afternoon (16:00–18:30) adult €25.50, child €15.50. Children up to 2 years enter free, and 65+ pay €19.90 / €18.80 / €17.70 by slot. The site advertises “from €25.50” for adults, which is the late-afternoon price, and 10% off online with a code — so quoting one figure without the slot misleads either way. [oceanario.pt, 26 Oct 2026]
- Getting there: Oriente metro (red line); several bus lines. [oceanario.pt]
- Main tank 1,000 m², 5 million litres, 7 m deep; about 16,000 animals of 450 species. [Wikipedia]
