The hike will come into effect from October 1.
"99 per cent of the people in Himachal rely on public transport only and this hike can be a blow to them," Kapoor said in a press briefing here.
He said employees, elderly citizens and agricultural community will be the worst hit by the hike.
"Most of the commuters of the state travel within the 5 km radius to earn their livelihood. The increase in the bus fare from Rs 2 to 5 is a blow to them," he said.
He said BJP will keep pressing the government to roll back the bus fare hike.
