The beam of light in Thien Cung grotto

A "highlight" of Thien Cung grotto is located at the second resting point, which is still within the first chamber of the cave.

At this spot, on beautiful sunny afternoons, the brilliant sunlight shines through the cracks in the cave walls, filling the interior with light. The rays, refracting with the humidity inside the cave, create beams of shimmering, mystical light, resembling a rainbow of seven colors. What makes this area even more remarkable are two massive stone columns, combined with the arching ceiling above, which together create a scene reminiscent of the "Heaven's Gate." The harmonious combination of these beautiful images makes the place incredibly vivid and welcoming, offering visitors many delightful surprises.
