Water from the Gulf of Thailand is pumped into dammed fields and then left to evaporate naturally from the heat of the sun. After about a month, the salt is ready to be harvested, scraped into piles and collected. Women shovel salt into woven baskets hanging from men's shoulders, trying to keep them in balance. The salt collected is transported from from these fields for cleaning and distribution. Ban Laem being the largest producer of salt in the area, you can see this spectacle everywhere in the district. Follow the 4012 and 4028 roads for some good spots, passing through Laem Phak Bia for great drone views. There's also a salt festival early march with salt sculptures and market stalls.
