Cheddar Gorge and Caves will be undertaking the work in the Lower Gorge from today until Friday, May 26.
The work follows recent inspections of the rock face throughout the lower gorge.
A spokesperson for Cheddar Gorge and Caves said: “The section of rock of concern is located mid-tier above the loading bay, between the Gorge Bear Shop and the entrance to Cox’s cave.”
They added: “All attractions and businesses will remain open and we look forward to welcoming all visitors.
“During this period, the road will be closed between the Gorge Bear Shop and the entrance to Cox’s Cave from Monday to Friday between 8.30am and 5.30pm to pedestrians, vehicles and cyclists.
“However, there is an alternative footpath available and car parking accessibility plan.”
During the days when the road is closed, the Riverside and Cox’s Cave car parks will only be accessible from the Cheddar village end of the gorge to the west.
The car parks in the upper gorge above Gough’s Cave will only be accessible by car by driving down through the gorge from the east.
The spokesperson said: “If you are visiting for the day, it may be advisable to arrive in the gorge from the east, as there is a larger quantity of car parking available in the upper gorge.”
