Trang An, Vietnam
It took us awhile to get from Hanoi to Trang An but it was worth it.
Beautiful landscapes, mountains, cliffs, caves. So peaceful. When you are here, nothing else seems to matters.
Boat ride ticket cost 150,000 Dong (7USD) and about 3hrs + long (if you enjoy your ride you can tip the boat person or help them paddle).
Highly recommended if your in the North of Vietnam!
