Hi Amazing, It is real. I have been there myself. When you fly back to Nepal stop over thailand. From Bangkok it takes around 17 hours by train and Ship to Kosamui. Very nice place, crystal clear white sand beach, a paradise Island. It is a very small island.You can go around the island by a motorbike in half an hour. Go to the lamai beach you will see this wonderful natural creation there. There are thousands of tourists going there and watch it. It is all true. You can also see in internet. http://thailandforvisitors.com/south/samui/sights/rocks.html
