The mine was originally opened in the 1940s and became a major source of tungsten and tin during World War II.
It is often referred to as the 'Mine of the Three Thousand Hills' due to the surrounding rugged terrain.
The name 'Pilok' is believed to originate from the phrase 'phi lok,' meaning 'ghosts deceive,' referring to early miners losing their way in the dense fog.
The village of Ban I-Tong, which serves the mine, was largely inaccessible by road until the Thai military constructed basic infrastructure in the 1960s.
Much of the original heavy mining equipment remains in situ, partially reclaimed by moss and jungle vegetation.
The site remains a border zone where the boundary between Thailand and Myanmar is marked by rugged mountain ridges.
Pilok Mine, historically known as Som Sak Mining, was once a thriving tin and wolfram extraction site nestled in the remote mountains of the Tenasserim Hills. Following the collapse of global tin prices in the mid-1980s, the mine ceased industrial operations and transformed into a historical landmark near the village of Ban I-Tong. The site retains rusted remnants of mining machinery, abandoned workshops, and decaying infrastructure integrated into the surrounding rainforest. Visitors can explore the preserved living quarters and equipment that reflect the site's mid-20th-century economic peak. The area is positioned directly on the Thai-Myanmar border, marked by the nearby Noen Chang Suek viewpoint. The village of Ban I-Tong has since pivoted to tourism, offering guesthouses and local markets while maintaining a secluded, misty mountain aesthetic.
The rusted, moss-covered mining machinery located at the primary entrance area provides the most iconic visual contrast between industrial history and nature.
Bring a light waterproof jacket as the area is frequently covered in dense mist, even in the dry season.
Pack comfortable, closed-toe walking shoes with good grip for navigating uneven, slippery terrain near the old machinery.
Carry a portable power bank, as high humidity and cold temperatures can drain mobile device batteries faster than expected.
Avoid visiting during the height of the monsoon season, as the steep, winding mountain roads to Pilok can become treacherous or impassable due to landslides.
Do not remove any rusted metal, tools, or industrial artifacts as souvenirs; respect the historical preservation of the site.
