Best months for Roopkund (Mystery Lake)
Curated season (May–Jun, Sep–Oct), with the off-months reasoned from the region’s monsoon and winter.
Day by day
Reconstructed from real per-day distance, ascent and camp altitudes. The line between points is a straight approximation — not a surveyed terrain profile.

Walking times are computed(Naismith’s rule, slowed for altitude) and scaled to your pace — plan generously. Exact camps and stage distances vary by operator.
Field notes
Water, last mobile signal, shelters, river crossings and bail-out points — the safety infrastructure of this route, plus the ground you actually walk on.
- Roadhead· Lohajung
Roadhead and last town. Nearest ATM is well below at Dewal/Tharali.
- Mobile signal· Lohajung
Last reliable signal. Ridges (Ali/Bedni) sometimes catch a bar — do not rely on it.
- Water source· Bedni Bugyal
Streams at Didna, Ali and Bedni. Carry full above Bhagwabasa — the summit push has none.
- Bail-out· Patar Nachauni
Descend via Bedni to Wan (nearest alternate road) or back to Lohajung.
- Medical / hospital· Lohajung
Nearest hospital is down-valley at Dewal/Gwaldam; evacuation runs on foot/pony to the roadhead.
- Care point· Bhagwabasa
5,029 m summit is reached fast — AMS is common. The climb to Junargali is steep hard snow.
Derived from the terrain above — confirm exact requirements with your operator for the season you go.
Curated from well-documented accounts of this route and anchored to named places on it — approximate, not GPS-surveyed. Conditions change with season and year; treat all water, and never rely on mobile signal.
Offline trek card
Emergency numbers, bail-out points and camp altitudes on one page — for when the signal (and your battery) is gone.
Print this or save it offline before you lose signal.
These reach a control room only where there’s a mobile signal — often nowhere on the trail. Carry your operator’s number and a satellite messenger for the high sections.

The GPX holds APPROXIMATE camp waypoints and a SCHEMATIC line — not a surveyed trail. Load it into OsmAnd, Gaia or Locus (which carry real offline topo maps) and walk with a guide. Do not navigate by the line itself.

Where to get your gear
What to buy, what to rent at the roadhead, and where to find each online — so you don’t overspend on a one-off trek.
- Trekking bootsBuy
Buy and break in weeks ahead — rented, ill-fitting boots are the #1 cause of a ruined trek. Waterproof, ankle-support.
- Base & mid layersBuy
Buy — they're personal, reusable and cheap. Moisture-wicking base + fleece/down mid.
- Down jacket (deep cold)Rent at roadhead
Rent at the roadhead for a one-off winter trek — bulky and expensive to own. −10 °C or better.
- Microspikes / crampons + gaitersRent at roadhead
Rent — snow-trek specific and rarely reused. Confirm they fit your boots before you leave the trailhead.
- Trekking polesBuy or rent
Cheap to buy, easy to rent — a pair saves your knees on icy descents.
- Sleeping bagRent at roadhead
Usually provided by your operator, or rent at the roadhead. If buying, match the season rating (−5 to −20 °C).
- Backpack + rain coverBuy
Buy — fit matters. 40–55 L for a self-carry trek, or a 20 L daypack if porters take the load.
- Sun & UV kitBuy
Buy — category-4 glacier sunglasses, SPF 50+, lip balm. UV is brutal on snow; skimping here causes snow-blindness.
- Headlamp + power bankBuy
Buy — headlamp for pre-dawn summit starts, insulated bottle, and a power bank (cold drains batteries fast).
Retailer links are plain searches (no affiliate) to help you find each item — compare prices and read reviews before buying. For a single trek, renting the big items is usually the cheaper, lighter call.
Train for it
- Serious base needed: 5 km under 30 min, weekly long hikes with a loaded pack; train 8–12 weeks out.
- Expect ~7 km of walking a day — train on stairs and inclines, not just flat ground.
- Do a few hikes carrying your actual daypack weight so your legs and shoulders are used to it.
- Add interval/cardio work — summit days at this altitude are long and relentless.
Acclimatise safely
- Know the AMS golden rules: don't ascend with symptoms; if worse, descend; HAPE/HACE = descend now.
- Carry a pulse oximeter and take a daily resting reading — a falling trend that doesn't recover means stop.
- Discuss acetazolamide (Diamox) with a doctor before you go — Shikhar never prescribes medication.
- This profile ascends fast (AMS: high) — build in a spare acclimatisation day if you can.
- Stay hydrated (3–4 L/day), eat well even without appetite, and avoid alcohol at altitude.
- Carry a personal first-aid kit; tell your operator about any medical conditions in advance.
