Phetchaburi Salt Fields (Ban Laem – Bang Khun Sai Route) The salt fields of Phetchaburi reflect the long-standing coastal way of life along the Gulf of Thailand. Most of the salt farms are spread along both sides of the coastal road SS.2021, which connects Haad Chao Samran to Ban Laem District and continues toward Bang Khun Sai. Located about 8 kilometers from Haad Chao Samran, the route reveals vast salt pans arranged in geometric plots that shimmer under the sunlight. The scenery is distinctly different from sandy beaches, offering a unique coastal landscape shaped by human ingenuity and natural forces.

 

The uniqueness of Phetchaburi’s salt fields comes from the coastal terrain, which consists of mudflats and a sea level suitable for natural evaporation. The Ban Laem area benefits from sediment carried by the Phetchaburi River and deposited at the river mouth, forming flat coastal land ideal for salt farming. Consistent sea breezes and strong sunlight from late year to early summer accelerate evaporation, making Phetchaburi one of Thailand’s significant sea salt production areas.

 

Historical evidence suggests that salt farming in Ban Laem dates back several generations, particularly during the early to mid-Rattanakosin period. Before refrigeration became common, sea salt was essential for food preservation and daily consumption, making it a strategic commodity. Trade routes transporting salt from Phetchaburi to central Thailand played a vital economic role. Salt farming was therefore not just an occupation, but a social structure that shaped families and coastal communities.

 

The traditional salt-making process begins with preparing and leveling the fields. Seawater is pumped into holding ponds and gradually transferred through a series of ponds to increase salinity before reaching the crystallization beds. As sunlight and wind evaporate the water, white salt crystals form. Farmers rake the salt into small pyramid-shaped piles in the middle of the pans. These white mounds against the wide sky have become an iconic image of Ban Laem. The main production season typically runs from December to April, when rainfall is low and sunshine is strong, creating ideal conditions for crystallization.

 

Driving along SS.2021, visitors will find scenic viewpoints and designated parking areas at intervals. Some spots provide informational signs explaining the salt-making process. Travelers can stop to take photos, enjoy the sea breeze, and appreciate the open coastal landscape. Early morning and late afternoon are the best times for photography, as the light beautifully reflects on the water-filled pans. During harvesting periods, visitors may witness real working scenes, offering a dynamic and culturally rich experience.

 

The way of life of salt farmers clearly reflects the relationship between humans and nature. Salt production requires understanding the rhythm of wind, sunlight, and tidal conditions. Even minor miscalculations can affect the quality of the crystals. Farmers therefore accumulate knowledge through years of continuous practice. While some modern technology is now used, traditional methods are still preserved because they ensure consistent and high-quality results.

 

Beyond economic value, salt fields also serve environmental functions. Coastal wetlands and salt pond embankments provide resting grounds for shorebirds, particularly during migration seasons. The stretch between Bang Khun Sai and Ban Laem is considered ecologically important. Balancing salt production with environmental conservation has become a key concern for local communities and relevant authorities.

 

For visitors, the Phetchaburi salt fields are ideal for those interested in local livelihoods, photography, and community-based tourism. Travelers should respect private property, avoid stepping onto salt pans without permission, and exercise caution when parking along the roadside, as traffic continues along this route.

 

Getting There From Haad Chao Samran, drive back to the main traffic light intersection and turn left toward Ban Laem District. Follow the coastal road SS.2021 for approximately 8 kilometers. The salt fields will appear along both sides of the road. This route continues and connects to Rama II Road, with clear directional signs along the way. Traveling by private car is the most convenient option.
