Koh Chang State Hospital
The hospital is located on the East side of the island, that is, you will need to drive through White Sand beach, Klong Son and both piers further to get to the hospital. If you do not have insurance or you want to save money on treatment, not at the expense of quality (I would even advise you to be treated there, rather than at White Sand), then you have a direct road to the village of Dan Mai, near which the hospital is located. Also, the hospital makes the necessary certificates and extracts for their further use in various state institutions.
