Kaew Komon Cave
Kaew Komon Cave or Calzite Crystal Cave is the highlight of Mae La Noi district

Kaew Komon Cave has the best examples of calcite crystals in Northern Thailand and is the only known example of a hydrothermal cave in the region.
History and Geological Origins
The cave’s formation began millions of years ago within Ordovician-era limestone, a rock rich in calcium carbonate. Through geological shifts and geothermal heat, hot water dissolved the calcite. As this superheated vapor evaporated, it recrystallized into the stunning formations that cover the cave’s walls and ceilings.
Kaeo Komon Cave was discovered by chance in 1993 by mining engineers who were searching for fluorite ore. To their surprise, they found an incredible cavern filled with pure white calcite crystals instead. The mining project was abandoned, and the area was later developed for tourism. In 2001, Her Majesty Queen Sirikit The Queen Mother visited the cave and bestowed upon it the name “Kaew Komon Cave” and named its five chambers based on their unique beauty.


The Five Chambers and Their Wonders
Inside Kaew Komon Cave, the journey takes you through five distinct chambers, each with its own breathtaking and unique calcite formations:
- Chamber of the Royal Heart Stream (ห้องพระทัยธาร): This is the first chamber visitors enter, featuring pure white calcite crystals resembling a flowing glacier or stream.
- Chamber of the Heavenly Cloud (ห้องวิมานเมฆ): Here, the crystals cluster together, looking like soft, fluffy clouds, creating a surreal, ethereal atmosphere.
- Chamber of the Mythical Forest (ห้องเฉกหิมพานต์): This room showcases formations that take on the shapes of mythical creatures from ancient Himmapan forest legends.
- Chamber of the Glass Curtain (ห้องม่านผาแก้ว): The highlight here is a curtain-like cascade of calcite, resembling a magnificent waterfall made of glass.
- Chamber of the Beautiful Crystal Flowers (ห้องเพริศแพร้วมณีบุปผา): The final and most spectacular chamber is adorned with exquisite calcite formations that look like a bouquet of blooming flowers.
