 When Chaitanya Mahaprabhu did parikrama (circumambulation) of Govardhana Hill while visiting Vrindavana in 1515 AD, he did not walk on the hill because he considered Govardhana as non-different from Lord Krishna.Therefore, traditionally Vaishnavas don’t step on Govardhan hill.It is believed that thousands of years ago, Lord Krishna picked up a hill and held it above His head, with his pinky finger, for 7 days to protect his kinsfolk from the wrath of rain God Indra.
