This trip to the mouth of the Chao Praya river starts by the ferry under Bhumipol bridge where motocycles and bicycles can cross the river to Phra Pha Deang. From there it's a short way to Suksawat rd. The first kilometers on Suksawat rd are busy, but once passed the Kanchanaphisek bridge, the traffic reduces.
At Phra Samut Chedi (ferry to Samut Phrakan) the road turns right and becomes smaller, and 2,2 km further when crossing a river, there is nearly no traffic anymore.
The last kilometers are all military domain. At the end of the road is The Phra Chulachomklao Fort. It includes a small museum, a battle ship and a restaurant at the border off the mouth of the Chao Praya.
On the way back I take a small elevated path short after the military checkpoint along a river. I enjoy the mangrove and several birds. The path ends about 3 km further and I have to come back by the same way.
Just before the klong Sapphasamit I turn left into a village. After leaving the village I cycle between lakes and klongs. The road ends in a village in nobody's land. About 2 km before the village is a turn to the north, going to the Klong Sapphansamit rd where it's possible to go straight to Suksawat rd, or after 4km turning left on Pracha Uthit rd.
