There are a host of travel and tour agencies all over Koh Chang. They can arrange flights, buses, trips, tours and pretty much everything that you wish to do .
Note that that by law in Thailand a travel agency must register with the Tourist Authority of Thailand (TAT). This ensures that only agencies are accountable for their actions. We suggest that you only use TAT approved travel agents. You can check if an agency is registered by asking for their TTT registration number. If you have any problems with any booking agent then you can contact the TTT on 039 597 255.
