Kids will love the water park, Aquaparque, in Caselas, and they can also learn a few new skills at the fantastic school of circus arts (Chapito) at Costa do Castelo. In addition, there's a city zoo, planetarium, oceanarium and amusement rides at Indios Park to enjoy. For young sports-lovers on holiday in Lisbon, canoeing, sailing and windsurfing are available at the Nautical Centre.
The mostly traffic-free Parque das Nacoes is a great place to chill out for the day, or you could hire some bikes and explore.
Move north and west from the city and you will hit the Estoril coast where you can explore seaside resorts like Cascais as well as the heritage-rich town of Sintra.
Lourinha offers a fantastic dinosaur museum - footprints of these prehistoric beasts can be viewed in the Serra de Aire. From Lourinha, travel to Peniche where boat trips run to the tranquil Berlengas Islands Nature Reserve.
Head south from Lisbon and you will discover the Costa Azul where beaches blend with fishing towns and natural parks. Setubal is one of the highlights - boat trips, dolphin-watching and birdlife can all be enjoyed here.
