As well as the best beaches in the UK (some say possibly in Europe) Bournemouth has won many "Blue Flag" awards for its overall cleanliness. There are terrific views over the Purbeck Hills.
During the summer months there is a fantastic free display of fireworks.

Boscombe has a long history of tourism in Dorset. For those who enjoy surfing it should be a must visit location. Convenient for kids as well as adults.
