Gangotri, Yamunotri, Kedarnath and Badrinath are collectively known as the "Chaar Dham". Gangotri, Yamunotri are origins of holy rivers Ganga and Yamuna where as Kedarnath and Badrinath are one of the holiest places of worship for Lord Shiva and Lord Vishnu devotees respectively.
All Chaar Dhams lie in different corners of Garhwal region and are generally done as part of what's termed as Chaar Dham circuit itineraries. These itineraries typically are ex-Haridwar or Ex-Delhi.
Gangotri (277 kms from Haridwar) is the origin of the holy river Yamuna and therefore very significant Hindu Pilgrimage.
Typically only Yamunotri itinerary guests stay at Barkot and from here Yamunotri can be approached.
Duration: 2 nights ex-Haridwar
