The map to Fort Phra Sumen shows the way to Fort Phra Sumen on Phra Sumen Road, off Chakrabongse Road. The fort is located at the bend of Phra Sumen Road about 300 m from the Chakrabongse junction. The Banglamphu Canal is to the east of the fort.
Santichai Prakarn Park is between the fort and the Chao Phraya River. This is one of the vantage points to watch the Royal Barge Procession.
