Know before you go

Good to know

Mobile network
BSNL and Jio work up to Sankri; other networks stop at Mori. BSNL is patchy around Osla and there is no signal at Seematra or Har Ki Dun.
Last ATM
Mori (one SBI ATM, often out of cash); carry cash from Dehradun or Purola
Nearest hospital
Mori and Purola for first care; Mussoorie or Dehradun (8-9 hours away) for serious cases
Water
The Supin (Thamsa) river and side streams run along the whole trail; boil or treat all water.

Highlights

  • Swargarohini, Black Peak and Hata peak rising straight from the head of a wide glacial valley
  • Centuries-old wooden villages like Osla and Gangaad with carved temples and stone-slab roofs
  • Walking beside the Supin (Thamsa) river through fir, pine, walnut and rhododendron forest in Govind Pashu Vihar
  • Optional side walk from Har Ki Dun towards Marinda Tal and the Jaundhar glacier valley

Risks

  • The forest department shuts the trek after December until mid-March; first heavy snow from mid-December can block the trail beyond Kalkatiyadhar.
  • The Sankri-Taluka road is landslide-prone and often closed in the monsoon.
  • Nights at Seematra and Har Ki Dun drop below freezing outside summer, and Har Ki Dun at about 3,566 m carries a real risk of altitude sickness.
  • Medical help is far away: serious cases need an 8-9 hour drive to Dehradun or Mussoorie.

Know before you go

Questions

Is Har Ki Dun suitable for beginners?

Yes. Operators rate it easy to moderate and suitable for first-time trekkers: the trail is well marked and has no technical sections. Trekking days are 4-10 km and the highest point is about 3,566 m, so you still need to be able to jog 5 km in about 35-45 minutes.

When is the best time to do the Har Ki Dun trek?

April to June for spring flowers and snow patches, and September to November for clear autumn views. The trek is closed in the July-August monsoon, and the forest department shuts it after December until mid-March.

How long is the Har Ki Dun trek?

Most operators run it in 7 days from Dehradun, with 5 trekking days and about 35-38 km on foot from the Dharkot or Taluka road head. Longer versions that start walking from Taluka or add Marinda Tal come to 44-50 km.

How do I reach Sankri, the base village?

Sankri is about 190-220 km from Dehradun, a 9-10 hour drive via Mussoorie, Purola and Mori. Buses and shared jeeps run from Dehradun; from Sankri a local jeep takes you about 20-24 km to the road head at Taluka, Dhatmeer or Dharkot.

Is there mobile network and an ATM on the trek?

BSNL and Jio work up to Sankri, with patchy BSNL near Osla and no signal higher up. The last ATM is in Mori and often runs out of cash, so carry enough from Dehradun.
