For travellers who want to swap busy viewpoints for genuine wilderness, the Great Himalayan National Park is the Kullu valley's best-kept secret. A UNESCO World Heritage Site since 2014, this vast protected park shelters snow leopards, Himalayan tahr, musk deer and the rare western tragopan across forests, alpine meadows and glacial valleys — and you can sample it on a day walk or a multi-day trek.
Why it's special
Covering more than 1,100 square kilometres of the upper Beas and Sainj catchments, the park was recognised by UNESCO for its outstanding biodiversity. Because no roads, settlements or grazing are allowed inside the core zone, the ecosystems here are remarkably intact. It's one of the few places in Himachal where you walk through forest that feels truly untouched, with birdsong instead of engine noise and — if you're lucky and quiet — the chance of spotting wildlife.
Entry points and treks
The park has four main gateways, all on its western edge in the Banjar–Sainj area. Gushaini, in the Tirthan valley, is the most popular roadhead and the start of the wildlife-rich Tirthan trails. Neuli leads into the Sainj valley, Siund into the Jiwanal valley, and Barshaini sits on the north-eastern fringe. From Gushaini it's roughly an 8 km walk to the official park entry gate at Rolla, and a day trek to that boundary needs no special permit — ideal if you only have a day.
Longer routes, such as the Tirthan or Sainj valley treks up to the high meadows, run three to six days and need a permit and ideally a local guide. The park's ecotourism setup and registered guides in Gushaini can arrange these.
Getting there from Naggar
The park is about 75 km from Kullu and 63 km from Bhuntar, reached via Aut on the Mandi road and then the link road into the Banjar valley. From Naggar, plan on a three-to-four-hour drive each way to Gushaini, so this is best as an overnight trip rather than a single-day dash. Many visitors spend a night or two in the Tirthan valley to make the most of the walking.
Practical tips
- Permits: entry is around INR 100 per day for Indians and INR 400 per day for foreign visitors, with concessions for students; arrange permits at the park office near Gushaini.
- Best season: April to June and September to November. Higher treks open only once the snow melts.
- Guides: hire a registered local guide for anything beyond the entry gate — it's safer and supports the community.
- Pack: layers, rain protection, sturdy boots and your own water and snacks; facilities inside the park are minimal by design.
This is a trip for slow travellers who value quiet and nature over checklists. If you'd like to combine it with time in Naggar, Ghar in the Hills makes a comfortable valley base before or after your park days.
Step into the wild
The Great Himalayan National Park rewards those willing to go a little further. Plan a couple of unhurried days, walk softly, and book your Naggar stay at Ghar in the Hills to bookend the adventure in comfort.
