Centro Ciência Viva de Lagos

Caravels of Portugal’s Age of Discovery set sail from Lagos, and the town’s Centro Ciência Viva is about how their crews found their way across oceans they had never seen. The exhibition, Do Astrolábio ao GPS (from the astrolabe to GPS), is a string of rooms and gardens that each give children something to do with their hands. It’s in the town centre, so it fits easily around a beach holiday, and it’s the obvious plan for a wet day or an afternoon too hot for the sand.

Welcome Aboard. A digital book tells the story of the Discoveries. Then children become navigators, using a quadrant and an astrolabe to work out latitude (how far north or south you are) from the stars. A group game asks them to plan a voyage to India by picking points on a world map, taking the winds into account.

Communication on board. Pairs race a stopwatch to send and decode a five-letter word in semaphore, the flag signals ships used before radio. Competitive siblings love comparing times.

Life on board. A room about ropes and knots, where children practise sailors’ knots. Staff demonstrations include disappearing knots and escape tricks in the style of Houdini.

The yellow submarine. The room children remember. You climb into a yellow submarine, look through the periscope and listen to sonar pinging as you explore a simulated ocean.

The lighthouse garden. Outside, a working lighthouse is a building project that needs regular maintenance, with construction challenges for children.

The boat garden. A water tank where children test how wind pushes small model caravels, and a full-size caravel replica with a treasure chest puzzle to crack.

Oficina Dóing. A maker workshop with 3D printers and 3D pens, robots, a chain-reaction arena and drones.

The big question the centre answers is: how do you know where you are at sea with no land in sight? Early sailors measured the angle of the Pole Star or the midday sun above the horizon with a quadrant or astrolabe. The higher it sat, the further north they were. That told them their latitude. Working out how far east or west they were was much harder, and it took accurate clocks centuries later to solve it. Today a GPS receiver does it using signals from satellites. Children can hold the old instruments, and it helps them see why the voyages were so dangerous.

The centre also runs Poças de Maré, a 90-minute guided rock-pool walk at low tide on one of six beaches around Lagos and the west coast: Praia da Luz, Praia da Batata, Praia do Alemão, Praia do Carvoeiro, Praia do Castelejo and Praia de Monte Clérigo. You wade into the pools and find out what lives there. It’s rated easy, open to children from three, and costs €60 for a group of up to eight (10% off for Lagos residents), with accident insurance included. Book at least 48 hours ahead; the meeting point is confirmed when you book. When we checked it ran until 31 October. Bring waterproof shoes, a hat, water and sun cream.

The centre also lists guided geology and palaeontology outings, including visits to dinosaur footprints on the beaches at Salema and Santa, plus astronomy activities. Ask the centre what’s running during your stay.

In the school holidays the centre runs Férias com Ciência for children aged 6 to 12, and you can leave them with the centre’s monitors. Mornings (9:30 to 12:30) focus on engineering, electronics and robotics; afternoons (14:00 to 17:30) cover biology, geology, chemistry, astronomy, physics and programming. When checked in September 2026 it cost €12 for a half-day, €18 for a full day and €75 for a week (€65 for a four-day week), with 10% off for siblings booked for the week. Lunch isn’t included, but children staying all day can have lunch at the centre. Groups are capped at 20, so register early.

The centre also runs a Science Club, monthly Ciência em Família sessions, science birthday parties and a family ticket with workshops; see the website for dates.

• Under-6s go free and enjoy the submarine and the boats in the water tank, though much of the exhibition is pitched at older children.
• Ages 6 to 9 love the submarine, semaphore race and treasure hunt in the caravel.
• Ages 9 to 12 can use the astrolabe properly, try the knots and get into the robots and drones.
• Teenagers interested in history or tech get most from the navigation story and the maker workshop.

When checked in September 2026 tickets were €3 for ages 6 to 17 and €6 for over-17s, with under-6s free. The family ticket (up to two adults with children up to 17) was €15. Seniors, teachers and students with a card pay €3. Entry is free for everyone on 29 January, 16 May and 24 November, and for Lagos residents on Sundays. The centre opens every day from 10:00 to 18:00 except 24, 25 and 31 December and 1 January.

It’s a compact centre, so a visit takes an hour or two. Groups, including home-education groups, can book visits, workshops and field trips at group rates.

The Zoo de Lagos is a short drive inland. For more Age of Discovery history, head west to the Fortaleza de Sagres. The Algarve’s other science centres are the Centro Ciência Viva do Algarve in Faro and the Centro Ciência Viva de Tavira.

How much is the Lagos science centre for children?

Can I leave my child at the Lagos science centre?

Yes, during Férias com Ciência in the school holidays, for ages 6 to 12, from €12 for a half-day. Book ahead.

Does the centre run rock-pool walks?

Yes. Guided 90-minute walks at six local beaches, for ages 3 and up, cost €60 for a group of up to eight and need booking 48 hours ahead.
