Apart from being visually stunning this place is really well "guarded" by the walls and cliffs so the only way to gain access to this place is via "official" entrance. But finding the entrance can be a feat of itself. I remember how I used to pull my theeth in frustration trying to get inside the sanctuary. However once you have figured out the easy way to do this you will be suprised that you ever had troubles with this. Checked the video for details.
