St Mary's Island - Udupi - Mangalore - India
This island is in Udupi which is a township in S-E-India.
One can take a small boat ride to the island from the town - there is nothing in this island - except some markers at all corners - but the sounds of the waves crashing into the shores is very relaxing.
The ferry costs 100 Rs ( or 2 $) and no one is allowed to stay back after sunset.
Walking around barefoot and feeling the waters is a good feeling.
