Ninh Binh
Ha Long Bay, without the sea
2 ways to do it, all bookable here
The same limestone as Ha Long, standing in flooded rice paddy instead of water, about two hours south of Hanoi. Trang An and Tam Coc are the two rowing routes: Trang An is the UNESCO-listed one and takes you through a series of low caves, while at Tam Coc the boatwomen famously row with their feet. Add the climb at Hang Mua for the view down over the river bend. May and June, when the paddy turns gold, is the picture everyone has seen.
