The terrain topography of the new trail is generally steep exceeding 100% in some stretches. However, the trail is an up-gradation of the footpath which the terrain topography is therefore not much of a concern.
After reaching Punakha Dzong, keep following the asphalt road along Mochhu until Khuruthang Town, a place to stretch the arms and spend a night at the cosy hotel.
