Nha Trang is a beautiful beach with hilly islands.  We took an all-day boat tour which included swimming, snorkeling and lunch.  And here is where I had my best experience of the trip so far:  snorkeling over a reef.  I’d never been snorkeling before, and I couldn’t believe how beautiful and incredible it was.  The water was warm and clear and full of colorful fish (who knew it really looked like “Finding Nemo”?)
