A reference guide to the routes we walk, drawn from our own trail time and the official record of the Great Himalayan National Park. Every trek below can be curated as an ElSi experience — paced, guided, and rooted in the valley it passes through.
The Great Himalayan National Park was constituted in 1984, formally notified as a national park in 1999, and recognised by UNESCO as a World Heritage Site in 2014 — protecting over 1,000 plant species and more than 30 mammal species, including the snow leopard, musk deer, and the western tragopan.
GHNP has no roads or settlements within its core zone. Every trek is walked on foot, entered by permit, and guided by locals who know these ridgelines the way you know your own street. Tirthan and Sainj valleys form the ecozone and interior of the Park; Seraj, further east near Jalori Pass, is the gentler, less-trekked side of the same mountain system.
Below is a working reference, not a fixed menu — treks can be shortened, combined, or slowed down further, in the ElSi way.
For a first crossing into the Park, or a trip with limited time. Still real forest, real climbing, real quiet.
Tirthan Valley · 2 Days · ~2,100m · ~10km round trip
The classic gateway trek from Gushaini, following the Tirthan River into the ecozone's forest line. A gentle, well-trodden first step into GHNP — big trees, river sound, and a night under the ridge.
Tirthan Valley · 2 Days · ~2,860m · ~10km round trip
A steeper pull to a meadow perched above the Park, with some of the widest interior views available on a two-day window. Good for travellers short on time but not on ambition.
Tirthan Valley · 3 Days · ~20km round trip
A quieter alternative through mixed forest, with a slower gradient than Rolla or Rangthar — well suited to first-time trekkers or a family group finding its trekking legs.
Seraj Valley · 1–3 Days · up to ~3,590m
The easiest and most rewarding introduction to Seraj — a walk through ancient deodar forest to a lake said to grant wishes to those who don't look back. Gentle enough for most fitness levels, and where ElSi's own first trek to Shangarh began.
Enough days to stop rushing. The Park stops feeling like a destination and starts feeling like a place you're temporarily part of.
Tirthan Valley · 3–5 Days · ~3,000m – 3,700m · up to ~43km
One of the most complete short treks in the Park — forest, meadow, and a genuine panoramic top, with route options depending on how many days you have.
Tirthan Valley · 3–5 Days · ~3,670m · ~20–30km
Wide alpine meadows and some of the best grazing-ground views in the ecozone — this is shepherd country, and you'll likely share the trail with someone's flock.
Tirthan → Sainj Valley · 4–5 Days · ~3,660m · ~25km
One of the few routes that physically connects Tirthan and Sainj valleys over a ridge — a trek for those who want to feel the geography, not just see it.
Tirthan Valley · 4 Days · ~25km round trip
Lesser-known routes through dense mixed forest, favoured by our guides when a group wants distance from other trekking parties entirely.
For travellers with the time, fitness, and appetite to go where the Park stops being an ecozone and becomes wilderness proper.
Tirthan Valley · 5–9 Days · up to ~4,300m
The trek to Tirth itself — the sacred spring at Hanskund Peak that gives the Tirthan River, and this valley, its name. A pilgrimage as much as a trek, through every habitat transition the Park has to offer.
Sainj Valley · 7–8 Days · ~3,900m · up to ~80km
Deep into the Sainj Valley's least-visited reaches — a longer, wilder counterpart to the Tirthan-side treks, for those who want to feel truly far from a road.
Tirthan Valley · 7–10 Days · up to ~50–65km
Among the longest and least-frequented routes in the ecozone — for travellers who have trekked with us before, or who arrive already fit and unhurried.
Tirthan Valley · 5–7 Days · up to ~4,050m
A demanding, high-altitude route not commonly walked — recommended for groups who've trekked with us before or arrive with prior high-altitude experience.
GHNP is a protected core zone — entry is only by permit, only on foot, and only with certified local guides, which is exactly how we'd choose to do it anyway. Multi-day treks here involve real climbing and require genuine preparation; a good general benchmark is that a reasonably fit trekker can comfortably manage altitudes up to around 4,000m.
Dress in layers you can add and remove through the day. Broken-in trekking boots with ankle support are non-negotiable — this is not the trek to wear new shoes on. A warm hat, gloves, insulated jacket, and a light waterproof layer cover you for the Park's fast-changing weather, even in summer.
The best trekking windows are April–June and September–November. We avoid the monsoon months, when trails wash out and leeches and slippery rock make the going genuinely unsafe, and deep winter, when snow closes the higher routes entirely.
For your specific trek, our guides will share an exact packing list and altitude briefing before you arrive.
Tell us your dates, your fitness, and what you're hoping to feel at the end of it. We'll match you to a valley and a pace, not the other way around.
