See all the famous landmarks of Switzerland in one go at Swissminiatur in Melide, Lugano. Children will love this area as there is also a few amusements rides and a miniature train that children (and adults) can go on for a tour round the park. You need to buy tokens from the machine to pay for the train and amusement rides.
You can either bring along your own picnic, as there is a large grass area nearby or alternatively you can buy something nice to eat in the on-site restaurant.
There is also a gift shop where you can buy a souvenir or even a lovely bar of Swiss chocolate as a reminder of your day out.
