The final segment goes to the top of Tangkuban Perahu / Upas Crater. Want to use a bicycle, trail motorbike, hiking, definitely this way. The gradient is actually not too steep compared to the Sukawana tea garden. Average at 6-10 %. There are segments that can be ridden if you really get traction, because the track is rock loose. If you can't ride it, just push it. No sin.
