Rescue workers from the Kusoldharm Phuket Foundation’s Patong unit responded to the incident, on Sai Nam Yen Rd, after receiving an emergency call.
At the scene, they found the 21-year-old British man, not named in the Kusoldharm Phuket report, who had lost control of his motorbike and plunged into the canal.
Rescuers used a sling to secure the motorbike, still bearing red licence plates, before pulling both the vehicle and the rider out of the water.
The tourist suffered only minor injuries, rescue workers confirmed.
It was not explained how the tourist and the motorbike ended up in the klong. If the tourist were travelling along the main road, it would appear that he missed the bridge.
