High in the Garhwal Himalayas, at 16,499 feet, sits Roopkund Skeleton Lake — a small glacial lake ringed by the bones of several hundred people. This mystery has puzzled scientists, trekkers, and storytellers since the remains were first reported in 1942. For eight years, you couldn’t legally trek there at all. That’s just changed.

Why You Can Only Just Trek Here Again
In 2018, the Uttarakhand High Court banned overnight camping in the state’s high-altitude bugyals (alpine meadows) to protect these fragile ecosystems. Bedni Bugyal, a key acclimatization campsite on the route to Roopkund, fell under that ban — effectively closing the trek for eight years, since there was no safe way to complete the route without camping there.
In July 2026, the Supreme Court set aside the ban, and trekking operations to Roopkund resumed. If you’ve had this trek on your list for years, this is genuinely the first real window to do it since 2018.
The Mystery That Made Roopkund Skeleton Lake Famous
British forest ranger H.K. Madhwal first documented the skeletons in 1942, and for decades the leading theory was simple: a group of pilgrims, caught in a sudden hailstorm around 800 CE, died together in one catastrophic event. It made for a tidy story — and it turned out to be substantially wrong.
In 2019, an international team of 28 researchers, including scientists from Harvard’s ancient DNA labs, published a genome-wide study of 38 skeletons in the journal Nature Communications. Their findings upended the single-event theory entirely. The skeletons actually belong to at least three genetically distinct groups, who died in separate incidents roughly a thousand years apart:
- 23 individuals with South Asian ancestry, who died sometime between the 7th and 10th centuries CE — consistent with the original hailstorm-era timeline, though possibly across several separate events rather than one
- 14 individuals with ancestry tied to the eastern Mediterranean — genetically similar to modern populations from Crete and the Aegean — who died roughly 1,800 CE, nearly a thousand years after the first group
- One individual with Southeast Asian-related ancestry, who died alongside the Mediterranean group
None of the individuals studied were related to each other, and isotope analysis showed the two main groups ate noticeably different diets. The genuinely strange part: researchers still can’t explain what a group of 19th-century Mediterranean travelers was doing at 16,499 feet in the Indian Himalayas, with no historical record of any such expedition. As the study’s co-author put it, they’ve tried to trace every plausible explanation and come up short — the presence of the Mediterranean group remains a real, unresolved puzzle.
The Trek Route
Most itineraries begin at Lohajung (accessible by road from Dehradun, roughly 9-10 hours away) and follow a route through:
- Didna / Ali Bugyal / Bedni Bugyal — lush alpine meadows, among the most scenic stretches of the trek, now reopened for camping
- Patthar Nachauni (“dancers turned to stone,” per local legend) and Bhagwabasa — higher camps as the trail gets more exposed and rocky
- Roopkund Lake itself, at 15,756-16,499 feet depending on the exact measurement point
- Junargali Pass, the trek’s highest point at around 16,156 ft, offering views of Nanda Devi, Trishul, and Chaukhamba
Daily distances vary widely — as little as 4 km on the final push to Roopkund, up to 15 km on descent days — which is part of why total trek duration ranges from 6 to 9 days depending on the operator and pace.
When Can You Actually See the Skeletons at Roopkund Lake?
Unlike most Himalayan treks, when you go genuinely changes what you’ll see:
- May-June: Lower sections are green and blooming, but higher camps like Bhagwabasa can still be under several feet of snow, and Roopkund Lake itself may be frozen solid — meaning the skeletons aren’t visible at all
- September-October: Skies are typically clearer, and this window offers the best chance of actually seeing the exposed skeletons at the lake’s edge
If witnessing the skeletons is part of why you’re going, September-October is the safer bet.
Difficulty and Preparation
This isn’t a beginner trek. Multiple operators recommend 30-45 days of dedicated fitness preparation beforehand, including cardiovascular training — being able to comfortably run 5 km is a commonly cited benchmark. Trekkers with prior experience at 12,000-14,000 ft altitudes will manage more comfortably; if this is your first or second trek ever, expect the summit day and high-altitude sections to be genuinely difficult.
How to Reach Lohajung (Base Camp)
- By air: Nearest airport is Pantnagar (Jolly Grant), roughly 220-250 km away
- By train: Nearest railhead is Kathgodam, approximately 210-235 km from Lohajung
- By road: Most trekkers drive from Dehradun (approx. 9-10 hours) via Rishikesh, Devprayag, and Karnaprayag

Frequently Asked Questions
Is the Roopkund trek open in 2026? Yes — after an 8-year ban on high-altitude camping (imposed in 2018), the Supreme Court set aside the restriction in July 2026, and trekking operations have resumed.
What is the mystery of Roopkund Skeleton Lake? Hundreds of human skeletons lie around this Himalayan lake. A 2019 genetic study found they belong to at least three distinct groups who died roughly a thousand years apart — including a group with Mediterranean ancestry from around 1800 CE, whose presence in the Himalayas remains scientifically unexplained.
How difficult is the Roopkund trek? Moderate to difficult. It covers roughly 53 km round trip over 6-9 days, reaching a maximum altitude of about 16,499 ft. Prior high-altitude trekking experience is recommended, though prepared beginners can complete it.
When can you actually see the skeletons at Roopkund? September-October generally offers the best visibility, since the lake can still be frozen and snow-covered during the May-June window.
Do I need a permit to trek to Roopkund? Yes, forest department permits are mandatory for the Roopkund trek.
How do I get to the Roopkund trek’s base camp? Lohajung is the standard base camp, reachable by road from Dehradun (approx. 9-10 hours) or via the nearest airport (Pantnagar) and railhead (Kathgodam).
