Atok has a land area of 21,499 hectares (53,130 acres). The land is characterized as mountainous with many steep cliffs. The highest point in the Philippine Highway System is located at Barangay Paoay along Halsema Highway, at 2,255 metres (7,400 ft) above sea level.
Atok is about 46 kilometres (29 mi) from Baguio City.
During the cold months of the year, the municipality experiences very low temperatures reaching 9 degrees Celsius. This causes frost to settle on the ground, causing millions of damage to crops, but drawing tourists to the town.
The area of Atok was previously referred to by the natives and Spanish colonizers as "Chontog", an Ibaloi word for "mountainous". Spanish military officials and missionaries arrived at Chontog in 1892, establishing precedencias (tax collection stations) in the area and its surrounding settlements.
The Ibaloi phrase "Nay patok shi Chontog", which means "on the mountain top", was later shortened to "Atok".
In August 13, 1908, Benguet was established as a sub-province of the newly-created Mountain Province with the enactment of Act No. 1876. As a result, six townships of Benguet were abolished, but Atok remained a constituent town of Benguet sub-province.
World War II
During the Second World War, Atok was the scene of fierce pitch battles between the military forces of the 1st, 2nd, 11th, 12th, 13th, 15th and 16th Infantry Division of the Philippine Commonwealth Army, 1st Infantry Regiment of the Philippine Constabulary, the USAFIP-NL 66th Infantry Regiments, the Igorot and Cordilleran guerrilla fighters and the Japanese Imperial Army forces. This is so because of the terrain along the Halsema road which is suited and ideal for the Filipino troops and guerrillas to mount ambushes and use the Philippine Commonwealth military and recognized guerrilla’s strategy of fighting. The place is now called the “Guerrilla Saddle” located at km. 26, Caliking, Atok.
On June 25, 1963, then-President Diosdado Macapagal issued Executive Order No. 42 converting eight (8) of the thirteen (13) towns (designated as municipal districts) of Benguet into regular municipalities. Atok was among them.
On June 18, 1966, the sub-province of Benguet was separated from the old Mountain Province and was converted into a regular province. Atok remained to be a component municipality of the newly established province.
