Pachmarhi is a hill station in Madhya Pradesh state of central India. It has been the location of a cantonment since British Raj. It is widely known as Satpura ki Rani (The name Pachmarhi is believed to be derived from the Hindi words Panch ("five") and Marhi ("caves"). According to a legend, these caves were built by five Pandava brothers of Mahabharatha era during their thirteen years of exile. The caves are situated on a hilltop and provide an excellent vantage point.
At the time of the British arrival, the Pachmarhi region came under the kingdom of the Gond king Bhawut Singh, although it was not a populated village or town at that time. Captain James Forsyth of the British Army along with Subhedar Major Nathoo Ramji Powar who was later made the Kotwal (Incharge of the armoury (Koth)of Pachmarhi, spotted the plateau in the Pachmarhi region in 1857, while leading his troops on the way to Jhansi. It quickly developed into hill station and sanatorium for British troops in the Central Provinces of India.
The population in 1901 was 3,020, rising to double that number in the hot summer months. Pachmarhi also served as the summer capital for the Central Provinces.
The forest around the town is home to many rare varieties of plants. UNESCO added Pachmarhi park to its list of Biosphere Reserves in May 2009.
