Hà Giang is a province in northern Vietnam, bordering China. It's known for its forested limestone and granite mountains. The laid-back provincial capital, also called Hà Giang, sits on the Lô river. North of the capital, the Quản Bạ Valley has green hills and caves, and is the location of the Quản Bạ pass, also known as Heaven's Gate for its panoramic views over terraced rice fields below. This route route is a loop popular with motor cyclists and follows the QL4C northeast from Hà Giang to Bảo Lâm, and the QL34 southwest from Bảo Lâm. The landscape is spectacular with Nguom Ngao caves, Ban Gioc waterfalls and incredible passes and traditional villages. Until recently, it has been cut off from visitors by the Vietnamese government, and has therefore escaped the relentless march of civilisation ...Note that you do require a permit when heading north of Ha Giang or Meo Vac which was easily organised by our helpful Vietnamese contact. AMAZING.
