Kedarnath Temple is a pilgrimage site among Hindus located 14 kms from Gaurikund and can be reached by foot or horse (please use your feet and not the poor horses).
A 7-minute helicopter services are also available by paying Rs. 7000 for two way, Rs. 4000 going up and Rs. 3000 coming down.
We went there one week before it closed for winter when people and traffic are less, hotels (lodging) are cheaper but food variety is less which could end you eating daal-chawal-sabzi.
Air is definitely colder and chillier so get all those wind/cold cheaters ready.
