Samut Prakan Criminal Court is alongside the Chao Phraya River just as you enter the city. When you come from Bangkok along Sukumwit Road, you will come to a traffic light at the City Hall. On your right you will also see a smaller version of Big Ben. Sukhumwit Road turns left here in order to bypass the city. You need to go straight across and enter the city.

Less than 300 metres from the traffic lights, you will see the courthouse on your right. It is a very tall building and you cannot miss it. Opposite is the police station. If you are coming by car, you can turn right here and straight into the court. Parking is a problem if you don't arrive early. It is possible to park out on the road, or try along the river near the City Hall. If you miss this turning you will find that you are now on a one way system. You just need to go around the block and come back on the other road.
