40 to 50km. Gaofeng & GaoShan & The Black Hills
Probably best done on an e-MTB. Gets kind of steep and some big drops you might want to walk on!
Can try the back route into GaoShan, then there are various small hill loops in GaoFeng and then head north to the Black Hills.
A collection of a few routes. Most are not easy gravel but more mountain trail MTB routes with some HnB.
