The Undercliff Walk has been closed following fears over safety following a rock fall.
Brighton and Hove City Council have temporarily closed the pathway from Brighton Marina to Saltdean following “constant and significant chalk fall” in the area.
The path will not reopen until there is no longer a “risk to public safety”.
A council spokesman urged the public to obey signs and fencing in the area.
He said: “Due to constant and significant chalk fall, we have taken the decision to temporarily close the Undercliff Walk to protect the health and safety of those who use it.
“For your own safety, please obey the signs and fencing in the area.
“Although most of Undercliff Walk is closed, the public can still access the beach, Molly’s Cafe and Whitecliffs Cafe via the Rottingdean Ramp and Saltdean subway.
“We will reopen the Undercliff as soon as possible, but only when there is no longer a risk to public safety.”
It comes as a visitor centre at an eroding cliff at Birling Gap is being moved before part of the building falls into the sea.
