The razor clams found here, Solen regularis, are locally called 'Hoi Lot'.
The sandbar's formation is heavily influenced by the sediment outflow of the Mae Klong River.
During low tide, visitors can walk significant distances out into the Gulf of Thailand on the exposed mudflats.
The brackish water environment supports a unique food chain distinct from pure saltwater or freshwater ecosystems.
The area is a popular destination for domestic tourism focused on seafood culinary experiences.
Don Hoi Lot is a 3-kilometer-long sandbar located at the mouth of the Mae Klong River, formed by the accumulation of sediment in the Gulf of Thailand. It is specifically renowned for its high concentration of Solen regularis, known locally as razor clams. The sandbar is accessible primarily during low tide, when the receding waters reveal vast, muddy flats where clams reside. Numerous seafood restaurants line the adjacent coastline, serving locally sourced shellfish dishes. The ecosystem is brackish, supporting unique mangrove vegetation and specific marine fauna that thrive in the fluctuating salinity levels. The area serves as a significant hub for coastal aquaculture and traditional artisanal fishing methods.

Wear sturdy footwear suitable for thick, wet mud if you plan to walk on the sandbar.
Check local tide tables before arrival to ensure you visit when the sandbar is fully exposed.
Bring mosquito repellent, as mangrove areas often have high insect activity.
Do not attempt to walk on the sandbar during high tide; avoid vendors who do not follow standard hygiene practices for shellfish.
Avoid digging for clams in restricted conservation zones if marked; dress modestly as it is a local community area.
