Oceanario de Lisboa tickets 2026: 25 to 29 euros by time slot

Oceanario de Lisboa charges between 25 and 29 euros for an adult ticket in 2026 depending on when you go in, according to the aquarium's own ticket page. The morning slot from 10:00 to 11:30 is 29 euros, the early afternoon slot from 12:00 to 15:30 is 27 euros, and the late afternoon slot from 16:00 to 18:30 is 25 euros. The page summarises this as tickets from 25 euros, which is the cheapest slot rather than the usual price.

Children and seniors follow the same curve

Children aged 3 to 12 pay 17, 16 or 15 euros across the same three slots. Visitors aged 65 and over pay 19, 18 or 17 euros. Children aged 0 to 2 are free. There is also a flexiticket at 41 euros per adult with no fixed date or time, valid for one visit within seven days, which costs about 12 euros more than simply booking the cheapest slot.

The online discount and the clock

The ticket page advertises 5 percent off when buying online with the code ONLINE5, so the gate price is effectively the higher one. Opening is daily 10:00 to 20:00 with last entry at 19:00, which means the late afternoon slot is the last one sold and the one most likely to be gone on a busy day.

What a family pays

Two adults and two children aged 3 to 12 in the late afternoon slot pay 25 plus 25 plus 15 plus 15, which is 80 euros, or about 76 euros after the online discount. The same four in the morning slot pay 92 euros. Choosing the time of day is worth roughly 12 euros to that family.

The page does not say whether the 5 percent code applies to the flexiticket as well as the timed slots.
