The YDNP have just published a closure notice due to repitching works on the path up Ingleborough. It's on the route up from the Hill Inn (Chapel le Dale) on the steep section beyond Humphrey Bottom before you reach the ridge near Green Hill and turn right to ascend Ingleborough. This path is popular with Three Peaks walkers, amongst others.
