The Jurassic coast line is filled with many gems to visit, such as;
Swanage, a beautiful typical English seaside town, with lovely knick knack shops, tea bars and restaurants.
Arne, where you can go for a lovely walk and see the beautiful cattle, etc.
Weymouth, about 40 mins drive, or you can go by train from Hamworthy, or by bus, which takes a bit longer.
Bournemouth, beautiful blue flag beaches, with an array of restaurants and shops.
You can even walk down to Hamworthy Park and if its open, the children can use the paddling pool or swim in the sea, and have a cuppa and a bite to eat by the cafe.
Poole Park, a beautiful Victorian park, with plenty to do, go for a boat ride on the lake, or just sit and people watch.
