Lisbon is a popular city break destination for couples and younger travellers, but there's still plenty to do for families. The city has a large zoo, aquarium, and a science museum with interactive exhibitions and a circus-themed play area. Weekends are the best time to visit. The kids can join workshops where they'll learn how to build their own inventions. Several family-friendly beaches are within a 30-minute drive of Lisbon city centre. Try Sao Joao beach. It has clean sands, changing facilities, loads of restaurants and a soft play area with bouncy castles.
