Phra Samut Chedi

Phra Samut Chedi is a white-washed stupa on the west bank of the Chao Phraya, directly across the water from Pak Nam, the town centre of Samut Prakan. Built during the reign of Rama II and completed under Rama III in the early Rattanakosin period, it originally stood on an island in the river — the “samut” (ocean/sea) in its name refers to that setting. Decades of silt have since joined the island to the west bank, so what was once a boat-only pilgrimage is now a short ferry hop.

The crossing is part of the experience: from Pak Nam pier — reachable by BTS to Pak Nam station — a small ferry runs regularly to the temple side for a few baht, taking a few minutes. On the far bank, the chedi rises in tiers above the temple grounds, its white plaster catching the light against the brown river water. Devotees circle the base making merit with incense and lotus offerings, and smaller shrines around the main stupa hold additional Buddha images. Longtail boats and barges pass close by on the river, a reminder that this stretch of the Chao Phraya is still a working shipping channel as it nears the Gulf of Thailand.

The biggest day to visit is the Phra Samut Chedi Worship Fair, held around the waning moon of the eleventh lunar month — typically October or November. It’s one of the largest temple fairs in Samut Prakan, with a procession that wraps a length of red cloth around the chedi; the exact dates move with the lunar calendar each year, so check before planning around it. Outside festival season, the temple runs at a working monastery’s pace rather than a tourist site’s — quiet on weekday mornings, busier with local worshippers at weekends.

Insider Tip: Time the ferry crossing for late afternoon, when the light is softer on the white stupa and the river traffic from Pak Nam’s fishing piers picks up.

Watch out: There’s no bridge or BTS extension to the temple side — skip the ferry leg and you’ll end up on the wrong bank looking at it from across the water.

The chedi sits within Samut Prakan, a short trip from the river-mouth fortifications at Fort Chulachomklao, another way to see this stretch of the Chao Phraya where it meets the sea.
