Essential Planning Guide
Tirthan Valley Trek — Complete Guide (2026)
Introduction
This is the flagship multi-day trek directly into the UNESCO-certified 'Core Zone' of the Great Himalayan National Park (GHNP). Starting at the Gushaini roadhead, trekkers follow the pristine Tirthan river deep into one of the most protected, biodiverse, and untouched temperate forest ecosystems left on the planet. The trail leads through Rolla up to the high-altitude meadow of Shilt Hut. From Shilt Hut, you are presented with a staggering, vertical wall of snow peaks that form the inner sanctuary of the park. It is the premier trek in India for sighting the elusive Snow Leopard (in deep winter), Himalayan Brown Bears, and the spectacular iridescent Monal pheasant.

Frequently Asked Questions
Will I definitely see a Snow Leopard?
If you trek in summer or monsoon, chances are absolute zero. In deep winter (Feb/March), if you camp at high altitudes in extreme conditions, you have a 10% chance.
Can I trek this without a local guide?
Absolutely NOT. The forest department strictly prohibits entering the core zone without a registered GHNP guide. The trails are deliberately kept unpaved to deter poachers.
What is the best time to do the GHNP Tirthan Trek?
The best time is from March to June for blooming flora and pleasant weather, and September to November for clear skies and autumn colors. July and August should be avoided due to heavy monsoon rains.
Do I need a permit to enter the Great Himalayan National Park?
Yes, permits are mandatory to enter the GHNP core zone. You can obtain them at the park gate at Sai Ropa or Rolla. The cost varies for Indian nationals and foreigners.
Are there any homestays inside the GHNP core zone?

Yes! The hike from Gushaini to Rolla is relatively flat and extremely well-marked, making it perfect for beginners, families, and nature enthusiasts.
