Dehradun is the capital of Uttarakhand at about 640 m in the Doon valley, and most visitors treat it as the hour-long stop before Mussoorie. It deserves a day of its own: the Forest Research Institute is one of the largest brick buildings in the world and among the finest colonial structures in India, Robber's Cave is a walk up a stream through a limestone gorge, and Sahastradhara's sulphur springs are the local Sunday outing. It is 35 km from Mussoorie, 55 from Rishikesh and 250 from Delhi.
The Forest Research Institute, which is the reason to stop
The FRI main building was completed in 1929 in Greco-Roman revival style, is over 150 metres long, and is claimed as one of the largest purely brick structures in the world. The scale is genuinely startling — long arcaded corridors, a vast lawn with the Himalayan foothills behind, and a building that looks as though it was transplanted from somewhere else entirely.
It is a working research institution and a deemed university, with six museums inside covering pathology, silviculture, entomology and timber. The museums are dusty and old-fashioned in the best way, with specimens from the 1920s still in their original cases.
Entry is ticketed and the grounds are open to walk. An hour and a half covers the building and one or two museums. Morning light on the facade is better than afternoon.
| Where | Time needed | |
|---|---|---|
| Morning | Forest Research Institute and museums | about 90 minutes |
| Late morning | Robber's Cave (Guchhupani) | about an hour |
| Afternoon | Mindrolling Monastery and the Great Stupa | about an hour |
| Evening | Paltan Bazaar, or Sahastradhara | as long as you like |
Robber's Cave
Guchhupani, usually called Robber's Cave, is a limestone gorge about 8 km from the centre where a stream runs through a narrow cleft. You walk up the streambed itself — ankle to knee deep in places, over stones — between walls perhaps two metres apart in the narrowest section, where at one point the water disappears underground and resurfaces.
It is a genuinely fun hour and it is not a dry sightseeing stop. You will get wet to the knee at minimum. Footwear that can be soaked is essential, and there are stalls at the entrance renting and selling exactly that.
It is busy at weekends and in summer holidays, when the gorge can be shoulder to shoulder. A weekday morning is a different place.
Mindrolling Monastery
Mindrolling at Clement Town is one of the largest Buddhist centres in India, rebuilt here after 1965, with the Great Stupa rising about 60 metres — among the tallest in the world. The stupa holds shrine rooms on several floors and a terrace with views across the valley.
It is quiet, free to enter, and almost entirely absent from Dehradun itineraries. Along with the FRI it is the strongest argument for giving the city a day rather than an hour.
Sahastradhara, and an honest note
Sahastradhara — the thousandfold spring — is 14 km out, where sulphur-bearing water drips through limestone into a series of pools and small falls. The water is cool and the sulphur content is held to be therapeutic.
It is extremely popular locally and on a summer weekend it is crowded, loud and commercialised, with a ropeway, food stalls and a lot of litter. Visitors arriving expecting a serene natural spring are usually disappointed.
Early morning on a weekday, or the off-season, is when it is pleasant. If the schedule only allows a weekend afternoon, it is reasonable to skip it in favour of Mindrolling.
The city itself
Dehradun was a colonial hill-adjacent town and the architecture survives in patches: the clock tower, the older parts of Rajpur Road, the cantonment. Paltan Bazaar is the main market and the place to buy the local basmati and the bakery goods the town is known for.
Dehradun is also an education town — the Doon School, the Indian Military Academy, the Survey of India — which gives the centre a different character from most Uttarakhand towns.
Getting there and onward
From Delhi it is about 250 km and five to six hours, with an airport at Jolly Grant 25 km out and good rail connections. From Haridwar it is 55 km and from Rishikesh about 45.
Mussoorie is 35 km and about an hour and a half up the hill, which is why Dehradun gets skipped. The better arrangement is a night in Dehradun with the FRI and Robber's Cave in the morning, then up to Mussoorie in the afternoon.
October to March is comfortable; summer in the Doon valley is hot and humid, and monsoon brings heavy rain with landslide risk on the roads up to Mussoorie.
Questions people ask
Is Dehradun worth stopping for?
A day, yes — the Forest Research Institute alone justifies it, and Mindrolling and Robber's Cave fill the rest. Most people give it an hour on the way to Mussoorie and miss all three.
Do I get wet at Robber's Cave?
Yes. You walk up the streambed, ankle to knee deep. Wear footwear you can soak — they are sold and rented at the entrance.
Is Sahastradhara worth visiting?
On a quiet weekday morning, yes. On a summer weekend it is crowded and commercialised, and Mindrolling Monastery is a better use of the afternoon.
How far is Mussoorie from Dehradun?
About 35 km and an hour and a half up the hill, which makes Dehradun a natural overnight before going up rather than a place to rush through.
