While Bristol is well known for it's hedonistic nightlife, it's also home to many young families looking for child-friendly events. A lot of the city's key tourist attractions like @Bristol (now renamed We The Curious) and the Aquarium run one-off events providing entertainment for all the family. Both are located on the Harbourside making that a key location for families visiting from out of town. The SS Great Britain is a big draw for families wanting to look round the famous naval ship, but they also offering chilling pirate stories as an additional attraction.
Windmill Hill City Farm and Bristol Zoo run regular workshops introducing children to environmental issues and you can also get the kids started on a budding acting career at the Tobacco Factory Theatre.
Ashton Court hosts the Bristol Balloon Festival annually. A wildly popular family event featuring (you guessed it) giant hot air balloons as well as flying demonstrations from the RFA and enough food and drink to keep any kid happy.
