The coaches have been forbidden to park or leave passengers at BIRLING GAP, confirmed the National Trust.
More than 600,000 people visit Birling GAP and the Seven Sisters Cliffs in East Sussex every year.
The coast guard recently urged people to stay away from the edges and basis of cliffs after a Great crack opened near Belle Tout’s lighthouse In Beachy Head.
However, visitors were seen looking at the edges of the cliff last week.
The National Trust said that coaches were no longer allowed to take tourists to BIRLING GAP and seven seven, as it tries to reduce the number of visitors.
A spokesman for The Trust said: “In Birling Gap, we welcome more than 600,000 visitors every year to this small rural cliff location that is vulnerable to coastal erosion.
“We have seen a significant increase in visits to the coach in recent years, with which the site cannot face.
“We are continuous to welcome visitors for car service, motorcycles, minibus and buses.”
