There are no cars or scooters for hire. A minibus connects Stavros with the tiny hamlet of Kalotaritissa on the far side of the island via Donousa's only road (€2, early June to late August).
Bicycle hire should be up and running in the near future and the island is very walkable.
The island's only taxi can drop you off in Kalotaritissa (€13) and elsewhere.
The small boat Margissa takes visitors to island beaches (€5) from June to September with a schedule based on weather and wind direction.
