Strangely, probably this is my favourite place on earth so far.
This is more than just the ray of light coming through the cave.
This is the height underneath the earth's surface.
A sinkhole with 50m diameter and 40-80m depth
This is a primordial forest with so many unidentified vegetation.
Droplets from the water infiltration.
A 300 meters walk underneath the ground.
This is the sound of the wind in silence and a sight in the dark.
A river flow below the earth surface
It is like a journey to the centre of the earth.
