Pin Valley National Park

Pin Valley is the side valley you take when Spiti starts feeling too brown. You turn south off the Kaza to Tabo road at the Attargu bridge, drop into a narrower valley along the Pin river, and within an hour the scenery shifts. There are actual fields of peas and barley, poplar trees lining the road, and villages that look softer than the rest of Spiti. The national park sits beyond these villages, a cold desert reserve set up in 1987 to protect snow leopards, Siberian ibex, and a specific slice of Trans Himalayan ecology. The park's core zone covers roughly 675 sq km, with a buffer of around 1,150 sq km. Altitude runs from about 3,500 metres at the river floor up past 6,000 metres on the ridges. It is the only national park in Himachal Pradesh that sits entirely in cold desert terrain, and it marks the old boundary between the Lahaul and Spiti sides of the district. The Great Himalayan National Park on the Kullu side and the Rupi Bhaba Sanctuary on the Kinnaur side together form one large protected corridor, with Pin sitting in the middle. Honestly, most travellers who say they have "been to Pin Valley National Park" have actually been to Mud village and the road that leads to it. The actual park interior is a foot access zone, reached by crossing the Pin river on a suspension bridge from Mikkim and hiking in. If you are here for a photograph of pretty green fields and a homestay with a valley view, the road is enough. If you want the park, plan a guided day hike from Mikkim or a longer trek.
