Black Peak — locally Kalanag or Kala Nag — is a 6,387m (20,955 ft) climbing peak in the Bandarpunch massif of the Garhwal Himalayas, graded Alpine AD-AD- · Assez DifficileEasier end of "fairly hard". One genuinely steep technical pitch — typically a fixed-rope ice wall or short rock step at UIAA III. Black Peak's 70° ice wall sits here. Read the grading glossary → . The Vertical Tribe runs it as a 15-day Dehradun-to-Dehradun expedition: a drive to Sankri, a three-day trek (Days 2–4) through Devsu and Ruinsara Lake to Kyarkoti base camp, an acclimatisation-and-skills day, load-ferry rotations through Advance Base Camp and Camp 1 to a summit camp at ~5,500m, and a pre-dawn summit push that includes a 75-foot fixed-rope ice wall at roughly 70°. Two buffer days are built in at the end. Dates and booking live on the Black Peak expedition page.
First climbed in 1955 by Jack Gibson and students of The Doon School, Dehradun — one of the earliest civilian-led first ascents in the Indian Himalayas, and the reason Black Peak still appears on Indian mountaineering school syllabi.
This guide covers the route phase by phase, the season windows, the technical bar, training benchmarks drawn from NIM Uttarkashi's published standards, equipment, costs, and the permit picture. TVT founders and lead guides are NIM Uttarkashi and HMI Darjeeling alumni; the operational detail below comes from running this peak across multiple seasons, not from the brochure.
What is Black Peak?
This guide covers Kalanag — the 6,387m Black Peak in Uttarakhand, India. Several unrelated mountains share the name Black Peak, including summits in Utah (USA), Pakistan, and Bhutan. If you are looking for the black mountain of the Indian Himalayas, you are in the right place.
The Mountain
Black Peak is the highest peak in the Bandarpunch massif at 6,387m (20,955 ft), a dramatic mountain group in the western Garhwal Himalayas of Uttarakhand, India. The massif comprises three major peaks:
| Peak | Altitude | Alternative Names |
|---|---|---|
| Black Peak (Kalanag) | 6,387m (20,955 ft) | Kala Nag |
| Bandarpunch I | 6,316m (20,722 ft) | Saraswati Devi Parbat |
| Bandarpunch II (White Peak) | 6,102m (20,020 ft) | Hanuman Parbat |
The Name
The name Kalanag literally translates to "Black Cobra" or "Black Serpent" in Hindi (काला नाग). The name has two commonly cited origins:
- The West Face: A wall of solid black rock that dominates one side of the mountain
- Serpentine Appearance: The black rock formation resembles the raised hood of a giant cobra—religiously significant as Lord Shiva's necklace in Hindu mythology
That dark west face is also why Kalanag reads as the black mountain of the Indian Himalayas: from the Har Ki Dun and Ruinsara valleys in Uttarakhand it stands visibly darker than the snow-covered Bandarpunch peaks beside it.
Location
The peak sits within the Govind Pashu Vihar National Park & Wildlife Sanctuary, a protected reserve spanning 958 square kilometers, established on March 1, 1955. Named after prominent Indian freedom fighter and politician Govind Ballabh Pant. The reserve holds Himalayan tahr, bharal and, rarely, snow leopard.
The Historic First Ascent
First Summit: 1955
By Jack Gibson and students from The Doon School, Dehradun, via the northwest flank.
Jack Gibson: The Pioneer
John Travers Mends Gibson OBE (1908-1994) was an English schoolmaster, scholar, and distinguished British Himalayan mountaineer who joined The Doon School in 1937 as a housemaster. Gibson taught at The Doon School from 1937 to 1953 and focused on teaching mountain skills to Indian students rather than on summit-bagging — the work that seeded post-Independence Indian mountaineering.
The 1937 Bandarpunch Expedition
Gibson's Himalayan legacy began even earlier. In 1937—his very first summer in India—he and colleague John Martyn reached the summit ridge of Bandarpunch alongside a young Sherpa named Tenzing Norgay—the same Tenzing who would later become the first person (along with Edmund Hillary) to summit Mount Everest in 1953.
This expedition sparked a lifelong friendship between Gibson and Tenzing. The Doon School returned to Bandarpunch in 1946 and 1950; the main peak was first climbed in 1950 by an expedition led by Maj. Gen. Harold Williams that included Tenzing (Wikipedia, accessed 2026-06-24). Tenzing dubbed it "the Doon School mountain" in his autobiography.
Legacy: The Doon School and Indian Mountaineering
The Doon School played a foundational role in post-Independence Indian mountaineering. From the 1940s onwards, masters and students including Gurdial Singh, Aamir Ali, Hari Dang, and Nandu Jayal were among the first Indians to undertake major Himalayan expeditions. Gibson's work at Black Peak and throughout the Garhwal region helped establish the traditions and training that would develop generations of Indian mountaineers.
Why Climb Black Peak?
A 6,000er with a real summit day
A 75-foot fixed-rope ice wall at roughly 70° is the crux — short, but the kind of pitch that makes Black Peak feel like a climb, not a snow walk.
An approach worth doing on its own
Three trail days from Sankri — through the oak-and-rhododendron forests above Taluka, the alpine meadows of Devsu, and a camp on the shore of Ruinsara Lake under the Bandarpunch range.
Summit views across Garhwal
From the top, Swargarohini, the rest of the Bandarpunch massif, and the Gangotri group to the east. Clear-air mornings are the norm in the post-monsoon window.
Still weighing options? Black Peak is one of several open Indian 6,000ers — the full comparison, with grade, season, and cost for each, is in our first 6,000m peak guide.
The Route: Sankri to Summit
The expedition moves through five distinct phases — approach, acclimatisation, higher-camp rotations, summit day, and descent.
Approach Trek (Days 1-4)
Dehradun → Sankri → Devsu Thatch → Ruinsara Tal → Base Camp
The journey begins with an 8-9 hour drive from Dehradun through the scenic Mussoorie-Purola-Mori route. Sankri village (1,950m) serves as the gateway—the same launching point for famous treks like Har Ki Dun, Kedarkantha, and Bali Pass.
Acclimatization & Training (Day 5)
At Kyarkoti Base Camp (4,050m), a full day dedicated to acclimatisation and technical skills training: crampon walking, ice-axe self-arrest, rope work, fixed-rope ascent, and glacier travel basics. Everything practised here is used again on summit day.
Higher Camps (Days 6-10)
Base Camp → ABC → Camp 1 → Summit Camp
The expedition runs the classic carry-high/sleep-low rotation. A load ferry to ABC then a move up; a load ferry to Camp 1 through crevassed glacier terrain then a move up; finally the move to a summit camp at ~5,500m.
Summit Day (Day 11)
The summit push starts around 2 AM. The route climbs steepening snow to the 75-foot fixed-rope ice wall at roughly 70°, then onto the upper snow slopes and the summit ridge. Top out at sunrise; descend the fixed line and drop back to ABC the same day.
Total duration: 10–12 hours round trip to ABC.
Descent (Days 12-15)
The descent retraces the approach route with buffer days built in for weather delays, recovery time, celebrating success with teammates, and certificate distribution at Sankri.

Buffer days / drive back to Dehradun
Reserved for weather delays or rest. If not needed for the expedition, these days can be used for exploring Sankri village, additional rest, or departure to Dehradun. Drive back to Dehradun when expedition concludes.
Best Time to Climb
The best time to climb Black Peak is May–June (pre-monsoon) or September–October (post-monsoon). These are the two windows TVT runs; the July–August monsoon and the November–February winter are out.
How cold does it get on Black Peak?
| Window | Day (base camp) | Night (base camp) |
|---|---|---|
| May–June (pre-monsoon) | 0°C to 10°C | Sub-zero |
| September–October (post-monsoon) | −5°C to 5°C | Well below freezing |
Both figures are base-camp readings. It gets materially colder with height: the summit camp sits 1,450m above base camp at ~5,500m, and the summit push starts around 2 AM, which is the coldest part of the day. Plan your sleep system and summit-day layers for the night column, not the day column.
Pre-Monsoon
May - June- Weather: Generally stable with occasional afternoon clouds
- Temperature: 0°C to 10°C (day), sub-zero at night
- Snow Conditions: Good consolidated snow, reliable ice wall
- Visibility: Clear mornings, possible afternoon haze
Post-Monsoon
September - October- Weather: Very stable, clear skies predominate
- Temperature: -5°C to 5°C (day), significantly colder at night
- Snow Conditions: Fresh snow possible, icier conditions
- Visibility: clearest skies of the year in the post-monsoon window
Seasons to Avoid
- Monsoon (July-August): Heavy rainfall, dangerous conditions, zero visibility
- Winter (November-February): Extreme cold, heavy snow, avalanche danger
Technical Difficulty & Requirements
Looking for a trek rather than a climb? Black Peak is a technical mountaineering objective — Alpine AD-AD- · Assez DifficileEasier end of "fairly hard". One genuinely steep technical pitch — typically a fixed-rope ice wall or short rock step at UIAA III. Black Peak's 70° ice wall sits here. Read the grading glossary → , with a 70° fixed-rope ice wall on summit day. It is not a trek and cannot be walked. The trekking routes into the same valley — Har Ki Dun and Ruinsara Tal — share the Sankri trailhead and reach the meadows below the peak without any climbing; both are covered in our guide to beginner treks in India.

Frequently asked
Which peak is called the black mountain of India?
Black Peak (Kalanag), 6,387m in the Bandarpunch massif of Garhwal, Uttarakhand. Its west face is a wall of dark rock that stands visibly darker than the snow-covered Bandarpunch peaks beside it — the origin of both the English name and the Hindi Kalanag ("black cobra"). It is a different place from the Black Mountains of Bhutan and from Kala Patthar in Nepal.
What is the best time to climb Black Peak?
The best seasons are May–June (pre-monsoon) and September–October (post-monsoon).
What happens if weather prevents the summit attempt?
We have 2 buffer days built into the itinerary for weather delays. If conditions don't permit a safe summit attempt, the team leader will make the final call. Safety is always our priority. Refunds for weather-related cancellations follow our cancellation policy.
Is the expedition suitable for solo travellers?
Yes. Most batches include solo climbers; we pair them in shared tents (same gender by default) and the group climbs as one rope team. Tell us if you want a single supplement.
What technical equipment do I need to bring?
All technical climbing equipment is provided including harness, helmet, crampons, ice axe, ascender, and carabiners. You need to bring personal gear like trekking boots, warm layers, and sleeping bag liner (optional).
