We did an overnight hike up to Chisapani on this trail. Stunning views from Chisapani and along most of the trail. It was a pretty relentless incline and much of it was stairs made from rocks. Very rewarding though. The hike up passed through a few national park checkpoints (with fees) and farmlands. Chisapani, like much of the surrounding area, was hit hard by the 2015 earthquake. Many of the hotels are in pieces, but a few were still operating. We hadn't planned the trip in advance, but on a whim joined some others. Very glad we did.
