The caves that hide the unknown!
Safeguarding some of the nature's deepest secrets inside them, caves are that part of the earth which we yearn to explore. Irrespective of how they are formed, caves look mysteriously terrifying, yet tempting.
Most caves are formed by the dissolving of large limestones but there are some that are just remnants or openings left behind by seas. While some require real strength and valour to be explored, others throw open their doors for even the meek public who wants to take a sneak peek into the beauty and majesty of these giant natural creations.
