The road that connects Ha Giang to Dong Van gives an idea of the vast expanses of natural beauty that you can see in the north east of the country. You travel along twisty roads surrounded on both sides by limestone mountains. The Dong Van Plateau is listed as a "Global Geopark."
You can visit the Ma Pi Leng Pass, at an altitude of 2,000 metres. The Nho Que River has carved a path through the heart of the mountains, and a few small dwellings dot the landscape. You encounter people from the Tay and Hmong ethnic minorities, who grow rice deep in the mountains. Before reaching the town, you come across a "tourism centre" where you can sleep on mats and where we shared some wonderful moments with our guests.
Otherwise, there's nothing special to see in the town of Dong Van. I know that people who enjoy hiking have a number of options when setting out from Dong Van.
