After an ascent of four km from the foot hills, adventurers reach the place called Silchouki and from there to the route towards east through the rugged and difficult track which expose them to range upon range of hills with trees. Its deep green looks in glaring contrast to the blue sky above like a impressionist canvas done by some crazy genius. After a trek of two km, one comes to a curving valley around which lie scattered, broken stone images, the base of which is strewn with rocks and the debris of dried up water courses.
Broken and scattered stone images are a mute testimony to the wear and tear of time. Popular legend about them is that in ancient times, the hill abounded with images of Hindu Gods and Goddesses. Subsequently, Nagas began to settle in the hill, took these Gods and Goddesses to be their ancestors and decided to install them at one place. They tide the images below their waists by long rope and began to drag them whereupon curses befell the Nagas who were hurtled hither-thither and instantly turned into stones. Nearby at one spot, pilgrims find a raised big stone altar on which sits a Naga saint, praying to some deity in penance for atoning the sins of their ancestors.
From there the trek descends sharply and after another walk of two km, a pilgrim or visitor sees in craggy silhouette a colossal cave, an awe inspiring and amazing spectacles. It is a dark place where the sunlight does not reach, where the thin air is suspended softly matching the delicate porcelain blue of the sky, where the visitor cannot but stare in bewilderment. Only a few dare descend its colonnaded steps to reach the base strewn with boulders, where the door of a mysterious and limitless tunnel opens. When, why and how was the tunnel dug up are lost in the mists of time? Was it man made or the result of some cataclysm in the past?
On the left and right sides of the caves are huge stone altars and the candle light shows up the faces of Naga saints, calm and statuesque in deep meditation and prayer to Lord Shiva on it. In the pitched darkness, the massive debris of boulders makes it difficult to locate exactly the entrance to the tunnel. But a closer scrutiny with the help of a torch or candle light reveals the entrance to the tunnel just in the middle and about 25 foot from the mouth of the cave. Both in height and breadth, the tunnel is two foot. One gets into it by crawling.
Legend says that a person who crosses the tunnel gets salvation from the cycle of births. But none can go beyond 300 foot of the tunnel. Another legend says that in the past, saints and sages made their journey through it to Kamakhya near Guwahati.
