On Koh Chang hourly share taxis run from the ferry terminals through all the beaches as far South as Lonely Beach from 6am until late evening. They can be flagged down anywhere and used to travel around the island. If you are planning to return to your hotel late at night don’t rely on the taxis since evening service is a bit erratic (and pretty expensive). Either book a taxi yourself for the evening or take advantage of the transport services that are increasingly being offered by many of the hotels, bars and restaurants on the island.
