Dear Liz,
I am very excited to know that you and your family are going to spend a few days in Vietnam next vacation.
In this letter, I would like to introduce you to one of the most famous nature wonder in Vietnam - Phong Nha - Ke Bang National Park. Located in Quang Binh Province, north-central Vietnam, it is a world heritage recognized by UNESCO in 2003. It not only keeps intact geology and geomorphology but also hides many mysteries of nature, which are majestic caves in limestone mountains formed millions of years ago. Coming to the place, you really must spend time visiting and exploring the most beautiful cave system in the world in the place.
In short, it is a magnificent place that makes tourists overwhelmed with its beauty.
I hope you can pay it a visit as it will not let you down.
I’m looking forward to seeing you soon.
Love,
