Kedarnath is named in honor of King Kedar who ruled in the Satya Yuga. He had a daughter named Vrinda who was a partial incarnation of Goddess Lakshmi. She performed austerities for 60000 years. In honour of her, the land is named Vrindavan. However, Kedarnath and its temple exist from the Mahabharata Era when the Pandavas are supposed to have pleased Lord Shiva by doing penance there.
There are 2 ways to reach Kedarnath: 1) By foot for a steep 14 km trek through a paved path (horses or palanquins are available for rent) from Gaurikund, which is connected by road from Rishikesh, Haridwar, Dehradun and other known hill stations of Garhwal and Kumaon regions in Uttarakhand 2) Through helicopter service.
