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 Advanced 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.
This guide covers the route phase by phase, the season windows, the technical bar, training, equipment, costs, and permits.

What is Black Peak?
This guide covers Kalanag (6,387m) in Uttarakhand's Bandarpunch massif — distinct from Kala Patthar in Nepal or mountains sharing similar Anglicised names.
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) | — |
| Bandarpunch II | 6,102m (20,020 ft) | White Peak |
The Name
The name Kalanag translates to "Black Cobra" in Hindi (काला नाग), named for two defining features:
- The West Face: A sheer wall of dark rock that dominates one side of the mountain and stands visibly darker than the snow-blanketed Bandarpunch peaks beside it, earning its title as the black mountain of the Indian Himalayas.
- Serpentine Appearance: From several approach angles, the black summit ridge resembles the flared hood of a cobra.

The Historic First Ascent
- First summit
- June 1955
- Party
- Jack Gibson and students of The Doon School, Dehradun
- Line
- Northwest flank
Jack Gibson (John Travers Mends Gibson, 1908–1994) was a schoolmaster at The Doon School in Dehradun from 1937 to 1953. Rather than pursuing high-altitude summit records, Gibson used the Garhwal Himalaya to teach self-reliance, expedition logistics, and technical skills to young Indian mountaineers.
Gibson had earlier climbed to the summit ridge of neighbouring Bandarpunch in 1937 alongside a young Sherpa named Tenzing Norgay (sixteen years before Tenzing's first ascent of Everest). In June 1955, Gibson led a team of Doon School staff and students to the first recorded ascent of Kalanag via its northwest flank. That expedition cemented Black Peak's status as one of India's foundational civilian mountaineering objectives.
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
Drive from Dehradun to Sankri (1,950m) along the Yamuna and Tons rivers (~220 km / 8–9 hrs). From Sankri, drive ~12 km along the Supin river to the roadhead at Taluka, then trek up the valley via Devsu Thatch (2,600m) and Ruinsara Lake (3,500m) to reach Kyarkoti Base Camp (4,050m) over three trail days.
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)
Descend from ABC past base camp to Ruinsara (Day 12), then trek ~14 km to Taluka and drive back to Sankri (Day 13). Days 14 and 15 serve as built-in buffer for weather delays or the drive back to Dehradun.

Day 14–15 Buffer days / drive back to Dehradun
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.
The two windows compared
| Factor | Pre-monsoon May–June | Post-monsoon September–October |
|---|---|---|
| Weather | Generally stable with occasional afternoon clouds | Very stable, clear skies predominate |
| Temperature | 0°C to 10°C by day, sub-zero at night | −5°C to 5°C by day, significantly colder at night |
| Snow conditions | Good consolidated snow, reliable ice wall | Fresh snow possible, icier conditions |
| Visibility | Clear mornings, possible afternoon haze | Clearest skies of the year |
| Best for | Warmer temperatures, longer daylight, wildflowers on approach | Crystal-clear views, autumn colours, fewer climbers |
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. We run Dev Kyara as a meadow trek under the same massif, without the summit ice wall.
Technical Skills Required
The qualifying bar
- One prior Himalayan trek above 4,000m

TVT files the IMF peak permit and the Govind Pashu Vihar forest entry; both sit inside the expedition cost. The IMF peak-fee schedule (foreign-team handling charges) lists below-6,500m peaks at US$500 for a party of two as of 10 Sep 2026. The IMF does not publish an Indian-team INR royalty on indmount.org. See the IMF permit cost estimator for the published dollar bands.
Realistic all-in budget
TVT's Black Peak fee is ₹80,000 per climber, Dehradun to Dehradun (brochure, 2026). IMF and forest permits sit inside that fee. Travel to Dehradun, insurance, and personal kit do not.
| Expense | Expected cost | Notes |
|---|---|---|
| Expedition fee (TVT) | ₹80,000 | Dehradun to Dehradun. IMF and Govind Pashu Vihar forest entry included. |
| Travel to Dehradun | ₹1,000–₹8,000 | Train, bus, or flight depending on city. Not a TVT quote. |
| Personal equipment | ₹15,000–₹60,000 | One-time if buying. Technical climbing gear is provided. Same band as our post-BMC cost note (2026-06-24). |
| Adventure insurance to 6,000m+ | ₹3,000–₹8,000 | Mandatory on this trip. Confirm the altitude ceiling in the policy wording. |
| Tips / buffer | ₹3,000–₹10,000 | Customary tips, a spare night in Dehradun, or a delayed train. |
| Realistic all-in budget | ₹1,00,000–₹1,60,000 | Lower end if you already own boots and travel cheap to Dehradun. |
What shapes the expedition fee
The fixed-rope ice wall, multiple high camps (ABC, Camp 1, Summit Camp), and mandatory IMF permit filing require a heavier operational footprint than a single-camp trekking peak. Transport from Dehradun, all permits, group climbing gear, and high-camp logistics are included in the ₹80,000 fee.

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 sheer 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 distinct from the Black Mountains of Bhutan and from Kala Patthar in Nepal.
What happens if a climber cannot pass the 70° ice wall on summit day?
Our 1:3 guide-to-climber ratio ensures that if a climber exhausts themselves or feels unsafe on the 75-foot ice wall, a lead guide ropes up to assist their safe descent back to Summit Camp or ABC, while the rest of the team continues the push. No climber is left unaccompanied on the mountain.
What is the toilet and waste setup above Base Camp?
Base camp at Kyarkoti has dry-pit toilet tents with bio-degradable covers. Above Advanced Base Camp (Camp 1 and Summit Camp), there are no permanent tents or pits; climbers use designated snow trenches and pack out all sanitary waste and non-biodegradable trash down to base camp under strict Leave No Trace protocols.
Where does drinking water come from at higher camps?
Fresh running stream water is available up to Advanced Base Camp (4,600m). At Camp 1 (5,200m) and Summit Camp (5,500m), all water is produced by melting clean snow and glacier ice using expedition stoves.
Is mobile network or charging available on the expedition?
The last cellular connectivity (Airtel and Jio) and mains electricity are in Sankri. From Taluka through the entire 12 days on the mountain, there is zero mobile signal and no charging facilities. Carry at least two 20,000mAh power banks and keep them inside your sleeping bag at night to protect batteries from the sub-zero cold.
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.
How do I reach Dehradun for the expedition?
Dehradun is reachable by train (Dehradun Railway Station), air (Jolly Grant Airport), and overnight bus from Delhi. Arrive a day early to allow for travel delays.
Book the Black Peak Expedition
Run by TVT with two NIM/HMI-alumni guides. Dehradun-to-Dehradun, 15 days, ₹80,000. Pre-monsoon (May–June) and post-monsoon (September–October) windows. Insurance, evacuation, and tips are extra.
