Bo Kluea Ancient Salt Pits 2, located near the Chao Pho Sang Kham shrine, is surrounded by local shops. The most famous products are spa salt (for skin scrubbing) and iodized edible salt. Even today, villagers continue to boil salt using age-old methods. Brine water is drawn from the pit, transported through bamboo pipes into a holding tank, then boiled in large iron pans until the water evaporates, leaving pure salt. The salt is then packed and sold locally. The process remains almost identical to that of the first salt pit.

The origins of this salt pit date back to the Permian period (around 280 million years ago) and the Triassic period (around 230 million years ago), when underground salt layers were formed. The discovery of underground brine made Ban Bo Luang a salt-producing site since ancient times.

The production process here is meticulous: brine is boiled inside enclosed salt houses to save firewood and shield the fire from wind. Clay stoves support iron pans with an average diameter of 85 cm, each requiring about 4 hours of boiling to produce 15–30 kilograms of salt. Production continues for 5 nights and 6 days before the furnace is rested, making fuel supply vital.

Although production has decreased due to the popularity of sea salt, Bo Kluea Ancient Salt Pits 2 remains a cultural heritage site, community learning center, and a unique travel destination that connects visitors to Nan’s long history of salt-making.
