People planning to visit the coast this Easter are being warned to be on their guard after a couple were cut off when a cliff suddenly collapsed on the Jurassic Coast.

The rescue mission at Charmouth beach has prompted a warning from HM Coastguard.

The Dorset couple were enjoying a quiet afternoon walk when part of a cliff collapsed, blocking their way back to the car park.

As their only other option was to go through the sea they decided to raise the alarm, and ended up being winched to safety by a search and rescue helicopter.

They were told that another half an hour and the tide would have covered the beach where they found themselves trapped.

One of the people rescued, who wanted to remain anonymous, said: “We didn’t want to make the situation worse than it already was by putting ourselves in further danger and called 999 and requested assistance from the Coastguard.

“Afterwards you question whether there’s anything you could have done differently, but we’re not the kind of people to take unnecessary risks.

“This sort of thing could happen to anyone and is a reminder of why you always need to have your wits about you at the coast.

“We now always make sure our mobile phones are fully charged before we head out and that we’re aware of tide times.”

People are being warned that conditions at sea or on coastal land can change very quickly and unexpectedly - making it unpredictable and dangerous.

Director of HM Coastguard, Claire Hughes said: “Never think it won’t happen to you.

“We’ve heard stories from so many people who have been out for walks or who are strong swimmers and experts in their watersports, who found themselves suddenly needing help because something has changed.

“The sea can still catch you out, the cliffs can prove treacherous and even a momentary lapse of concentration can put you in difficulty.

“We will always respond to those in need, but all we ask is that you think twice about what you do and where you go.”

If you get into trouble at sea or on the coast call 999 and ask for the Coastguard.
