Lisbon with kids aged 6-10

One huge central tank you keep coming back to, ramps and lifts all the way, and cheaper after 4 pm.

A full day out right on top of a metro station, but the cable car does not take strollers.

Hands-on science centre where touching everything is the point. Closed on Mondays outside summer.

Short cable car ride along the river. Easy win with small children after the aquarium.

Real walls to walk and peacocks to spot, free up to age 12. The climb to get there is the hard part.

The old yellow tram through Graça, Sé, Chiado and Estrela. Fun from age 4 if you get a seat.

A bus that drives into the Tagus. Minimum age 2, no strollers, 90 minutes without a stop.

Free neighbourhood park with playgrounds, a duck pond, a café and toilets, right on tram 28.

For football fans from about 7. Closed or restricted on match days, so check the fixture list.

The landmark of Belém. Children up to 12 are free, but there is little here for under-8s.

The coloured palace on the hill. A long day with timed entry, steep paths and stairs inside.

Free, quiet garden with a lake and ducks, good for a stroller nap. No ball games or bikes.
