Day 4: Since it was raining, we were not allowed to dive into waters from the Cruise. However, we were adamant to go for Kayaking. It was good day to go Kayaking, as it was not hot and sunny. Also, not many people wanted to go out on such weather. After couple of hours of kayaking returned to our cruise and head back to Hanoi.
It was a mesmerizing day to be in middle of ocean kayak all by yourself, deep green waters as far as you can see and these lime stone structures in between the ocean. After all this it was time to relax in Hanoi as next early morning there was a return flight.
