Warning over climbing on St Oswald's Bay landslip debris
Visitors to a beach in Dorset are continuing to ignore warnings to stay away from the cliff and debris from a landslip which happened last month.
A 20m (65ft) section of the cliff above St Oswald's Bay, east of Durdle Door, fell away overnight on 30 April.
Witness Mark Probin said teenagers were seen on Saturday scrambling up the bank, effectively "dicing with death".
Portland Coastguard said warning signs had been put up but it could not force people to take the advice.
The South West Coast Path above has been diverted and large signs advise people not to go near the cliff, which could be unstable in places.
Mr Probin, a local resident and photographer, said: "These two lads, mid to late teens, thought it would be fun to climb this land-slip.
"Rocks etc started to fall and those on the beach shouted comments to them, telling them to be careful as rocks are falling.
"Their reply was they are not throwing them so it's not their fault."
A spokeswoman for Portland Coastguard said the advice to people was not to climb on the rock, to act sensibly and to stay away from the landslip debris.
"That's our advice, if they ignore it that's up to them," she added.
