Moving between the different beaches and restaurants and visiting the small villages will be part of your Formentera experience, so wherever you stay on the island you will need transport.
Formentera is quite small and you will be able to get to any other part in less than 10/15 minute drive.
There are regular buses during the summer season that can take you to most parts of the Island, however…
most visitors prefer to get around by car, scooter or bicycle.
The best way to get around is by bicycle or scooter if your party consists of adults and teenagers, especially when you consider that the entire island is only 82 km2. Families with young kids, should better choose cars.
