Wat Lang San Prasit(วัดหลังศาลประสิทธิ์)is located in Samut Sakhon by the banks of the Tha Chin River. It is a new Wat but has some really beautiful buildings including a very decorative Ubosoth(Bot) and wihans. There is also a very picturesque water feature with footbridge linking the public area of the temple to the Bot. A huge naga stretches through the water and under the bridge. To the left of the ubosoth there is a tall statue of the Buddha in a classic pose.

Situated on the Tha Chalom peninsula the Wat is accessed by heading south from Samut Sakon on Highway 35 crossing the Tha Chin River and turning left to follow the road to Tha Chalom.

There is ample parking at the Wat and no charges are made for admission
