Crystal-clear waters now fill what was once a bustling lignite mining operation, transforming The Old Mine of Ban Sa into one of northern Thailand’s most striking artificial lakes. This flooded quarry in Phayao province creates an otherworldly landscape where steep mining walls plunge directly into turquoise water, offering visitors a glimpse of industrial heritage reclaimed by nature.
Photography enthusiasts flock here to capture the dramatic contrast between the geometric mining terraces and the pristine lake surface that mirrors the sky above. Swimming and kayaking are popular activities, with the deep, mineral-rich waters providing a refreshing escape from Thailand’s heat. Walking along the rocky shoreline reveals remnants of the mining infrastructure, while elevated viewpoints around the quarry’s rim offer panoramic perspectives of the water-filled crater. The silence is profound, broken only by gentle lapping of waves against stone walls and occasional bird calls echoing across the water.
Tranquility defines the experience at this remarkable site, where industrial scars have evolved into natural beauty. The isolation creates an almost meditative quality, far removed from Thailand’s busy tourist circuits. Visitors often describe feeling transported to another world as they stand on the quarry’s edge, gazing down at waters so clear you can see the submerged mining equipment below.
Early morning visits provide the best lighting for photography and cooler temperatures for swimming. The site is accessible by motorbike or car from Chiang Muan town center, though local transport options are limited. Bring sun protection, swimming gear if desired, and plenty of water as facilities are minimal. This unique destination rewards those seeking something different from typical Thai attractions, offering a peaceful retreat that showcases nature’s remarkable ability to heal industrial landscapes.
