Parts of Vietnam’s northeast are particularly isolated and fairly challenging to visit. However, this isolation adds to the region’s beauty, as many areas are still extremely undeveloped and unadulterated by tourism. Make the effort to explore this part of the country and you will be rewarded. Highlights include Ban Gioc Waterfall in Trung Khanh District and the road between That Khe and Lang Son, whose beauty of plunging ravines riddled with caves hides a grim and bloody past. To the north of Cao Bang is the cave in which Ho Chi Minh lived upon first returning to Vietnam from China. This region of Vietnam is also home to numerous ethnic minority groups, including the Tay, Nung, Zoa, Meo, Man and the San Chay. They live in some rather isolated areas and subsist through traditional means. This is one developing trekking area to watch.
